World Ocean


An ocean (from Greek Ὠκεανὸς, "okeanos" Oceanus) is a major body of saline water, and a principal component of the hydrosphere. Approximately 70.9% of the Earth's surface (~3.61 X 1014 m2) is covered by ocean, a continuous body of water that is customarily divided into several principal oceans and smaller seas.
More than half of this area is over 3,000 metres (9,800 ft) deep. Average oceanic salinity is around 35 parts per thousand (ppt) (3.5%), and nearly all seawater has a salinity in the range of 30 to 38 ppt. Scientists estimate that 230,000 marine life forms of all types are currently known, but the total could be up to 10 times that number.
Though generally described as several 'separate' oceans, these waters comprise one global, interconnected body of salt water sometimes referred to as the World Ocean or global ocean. This concept of a continuous body of water with relatively free interchange among its parts is of fundamental importance to oceanography.
The major oceanic divisions are defined in part by the continents, various archipelagos, and other criteria. These divisions are (in descending order of size):
  • Pacific Ocean, which separates Asia and Australia from the Americas
  • Atlantic Ocean, which separates the Americas from Eurasia and Africa
  • Indian Ocean, which washes upon southern Asia and separates Africa and Australia
  • Southern Ocean (proposed) or Antarctic Ocean, sometimes considered an extension of Pacific, Atlantic and Indian Oceans, which covers the waters that surround Antarctica.
  • Arctic Ocean, sometimes considered a sea of the Atlantic, which covers much of the Arctic and washes upon northern North America and Eurasia.
The Pacific and Atlantic may be further subdivided by the equator into northern and southern portions. Smaller regions of the oceans are called seas, gulfs, bays, straits and other names.
Geologically, an ocean is an area of oceanic crust covered by water. Oceanic crust is the thin layer of solidified volcanic basalt that covers the Earth's mantle. Continental crust is thicker but less dense. From this perspective, the earth has three oceans: the World Ocean, the Caspian Sea, and Black Sea. The latter two were formed by the collision of Cimmeria with Laurasia. The Mediterranean Sea is at times a discrete ocean, because tectonic plate movement has repeatedly broken its connection to the World Ocean through the Strait of Gibraltar. The Black Sea is connected to the Mediterranean through the Bosporus, but the Bosporus is a natural canal cut through continental rock some 7,000 years ago, rather than a piece of oceanic sea floor like the Strait of Gibraltar.
Despite their names, smaller landlocked bodies of saltwater that are not connected with the World Ocean, such as the Aral Sea, are actually salt lakes.

Ocean Exploration
Ocean exploration is a term of oceanography describing the exploration of ocean surfaces. It is also the period when people explored the ocean boundaries. Notable explorers include: the Greeks, the Egyptians, the Polynesians, the Phoenicians, Phytheas, Herodotus, the Vikings, The Portuguese, and Christopher Columbus. Travel on the surface of the ocean through the use of boats dates back to prehistoric times, but only in modern times has extensive underwater exploration become possible. Scientific investigations began with such early scientists as James Cook, Charles Darwin and Edmund Halley.

Marine Biology
Marine biology is the scientific study of organisms in the ocean or other marine or brackish bodies of water. Given that in biology many phyla, families and genera have some species that live in the sea and others that live on land, marine biology classifies species based on the environment rather than on taxonomy. Marine biology differs from marine ecology as marine ecology is focused on how organisms interact with each other and the environment, and biology is the study of the organisms themselves.

Scientific investigations began with such early scientists as James Cook, Charles Darwin and Edmund Halley. Ocean exploration itself coincided with the developments in shipbuilding, diving, navigation, depth measurement, exploration and cartography.


Early Exploration
  • 4500 B.C. Around this time, coastal cultures like those in Greece and China began diving into the sea as a source of food gathering, commerce, and possibly even warfare.
  • 4000 Egyptians developed sailing vessels, which were probably used only in the eastern Mediterranean near the mouth of the Nile River.
  • 4000 B.C. - 1000 A.D. Polynesian colonization of South Pacific Islands.
  • 1800 Basic measuring of the depths is done in Egypt.
  • 600 Phoenicians developed sea routes around the entire Mediterranean and into the Red Sea and the Indian Ocean. Going around Africa they reached England by sailing along the western European coast. Although they understood celestial navigation, they probably stayed within sight of land whenever possible.
  • 500-200 Greeks developed trade routes in the Mediterranean using the length of the day (corrected for the time of the year) to estimate latitude.
  • 450 Herodotus publishes a map of the Mediterranean region.

  • 200 Eratosthenes determines fairly accurately the circumference of the Earth using angles of shadows in Syene and Alexandria.
  • 150 B.C. Ptolemy produces a map of the Roman world, including lines of latitude and longitude, the continents of Asia, Europe, and Africa and the surrounding oceans.
  • 900 A.D. -1430 A.D. Vikings explore and colonize Iceland, Greenland, Newfoundland.
  • 1405-1433 Chinese send seven voyages to extend Chinese influence and impress their neighbor states. These expensive voyages are ended after a short time. See Zheng He (1371 - 1433).
  • 1410 Ptolemy's map of the oceans is published once more after European crusades capture Roman libraries from Arab peoples.

Age Of Exploration
Age of Exploration, was a period in history starting in the 15th century and continuing into the early 17th century during which Europeans engaged in intensive exploration of the world, establishing direct contacts with Africa, the Americas, Asia and Oceania and mapping the planet. Historians often refer to the 'Age of Discovery' as the pioneer Portuguese and Spanish long-distance maritime travels in search of alternative trade routes to "the Indies", moved by the trade of gold, silver and spices.

The Portuguese began systematically exploring the Atlantic coast of Africa from 1418, under the sponsorship of Prince Henry, reaching the Indian Ocean by this route in 1488. In 1492, racing to find a trade route to Asia, the Spanish monarchs funded Christopher Columbus’ plan to sail west to reach the “Indies” by crossing the Atlantic. He landed on an uncharted continent, then seen by Europeans as a “new world”, America. To prevent conflict between Portugal and Spain, a treaty was signed dividing the world into two regions of exploration, where each had exclusive rights to claim newly discovered lands. In 1498, a Portuguese expedition commanded by Vasco da Gama finally achieved the dream of reaching India by sailing around Africa, opening up direct trade with "Asia". Soon, the Portuguese sailed further eastward, to the valuable “spice islands” in 1512, landing in China one year later. East and west exploration overlapped in 1522, when Ferdinand Magellan led a Spanish expedition west, achieving the first circumnavigation of the world, while Spanish conquistadors explored inland the Americas, and later, some of the South Pacific islands. In 1595, the Dutch, French and English, who entered the race of exploration shortly after learning of these exploits, defied the Iberian monopoly on maritime trade by searching for new routes, first to the north, and into the Pacific Ocean around South America, but eventually by following the Portuguese around Africa into the Indian Ocean; discovering Australia in 1606, New Zealand in 1642, and Hawaii in 1778. Meanwhile, from the 1580s to the 1640s Russians explored and conquered almost the whole of Siberia.

The Age of Discovery is seen as a bridge between the Middle Ages and the Modern era, along with its contemporary Renaissance movement, triggering the early modern period and the rise of European nation-states. Accounts from distant lands and maps spread with the help of the new printing press fed the rise of humanism and worldly curiosity, ushering in a new age of scientific and intellectual inquiry. European overseas expansion led to the rise of colonial empires, with the contact between the Old and New Worlds producing the Columbian Exchange: a wide transfer of plants, animals, foods, human populations (including slaves), communicable diseases, and culture between the Eastern and Western hemispheres, in one of the most significant global events concerning ecology, agriculture, and culture in history. European exploration spanned until accomplishing the global mapping of the world, resulting in a new world-view and distant civilizations acknowledging each other, reaching the most remote boundaries much later.

Global Impact


European overseas expansion led to the contact between the Old and New Worlds producing the Columbian Exchange, named after Columbus. It involved the transfer of goods unique to one hemisphere to another. Europeans brought cattle, horses, and sheep to the New World, and from the New World Europeans received tobacco, potatoes and maize. Other items becoming important in global trade were the sugarcane and cotton crops of the Americas, and the gold and silver brought from the Americas not only to Europe but elsewhere in the Old World.

The new trans-oceanic links and their domination by the European powers led to the Age of Imperialism, where European colonial powers came to control most of the planet. The European appetite for trade, commodities, empire and slaves greatly affected many other areas of the world. Spain participated in the destruction of aggressive empires in America, only to substitute for its own and forcibly replaced the original religions. The pattern of territorial aggression was repeated by other European empires, most notably the Dutch, Russian, French and British. New religions replaced older "pagan" rituals, as were new languages, political and sexual cultures, and in some areas like North America, Australia, New Zealand and Argentina, the indigenous peoples were abused and driven off most of their lands, being reduced to small, dependent minorities.

Similarly, in coastal Africa, local states supplied the appetite of European slave traders, changing the complexion of coastal African states and fundamentally altering the nature of African slavery, causing impacts on societies and economies deep inland.

Aboriginal Peoples were living in North America at this time and still do today. There were many conflicts between Europeans and Natives. The Europeans had many advantages over the Natives. They gave them diseases that they had not been exposed to before and this wiped out 50–90% of their population.

Since being introduced by Portuguese in the 16th century, maize and manioc have replaced traditional African crops as the continent's most important staple food crops. Alfred W. Crosby speculated that increased production of maize, manioc, and other American crops "enabled the slave traders drew many, perhaps most, of their cargoes from the rain forest areas, precisely those areas where American crops enabled heavier settlement than before."

During the 16th century Chinese economy, under the Ming Dynasty, was stimulated by trade with the Portuguese, Spanish, and Dutch. China became involved in a new global trade of goods, plants, animals, and food crops known as the Columbian Exchange. Trade with European powers and the Japanese brought in massive amounts of silver, which then replaced copper and paper banknotes as the common medium of exchange in China. During the last decades of the Ming the flow of silver into China was greatly diminished, thereby undermining state revenues and indeed the entire Ming economy. This damage to the economy was compounded by the effects on agriculture of the incipient Little Ice Age, natural calamities, crop failure, and sudden epidemics. The ensuing breakdown of authority and people's livelihoods allowed rebel leaders such as Li Zicheng to challenge Ming authority.

New crops that had come to Asia from the Americas via the Spanish colonizers in the 16th century contributed to the Asia's population growth. Although the bulk of imports to China were silver, the Chinese also purchased New World crops from the Spanish Empire. This included sweet potatoes, maize, and peanuts, foods that could be cultivated in lands where traditional Chinese staple crops—wheat, millet, and rice—couldn't grow, hence facilitating a rise in the population of China. In the Song Dynasty (960–1279), rice had become the major staple crop of the poor; after sweet potatoes were introduced to China around 1560, it gradually became the traditional food of the lower classes.

The arrival of the Portuguese to Japan in 1543 initiated the Nanban trade period, with the Japanese adopting several technologies and cultural practices, like the arquebus, European-style cuirasses, European ships, Christianity, decorative art, and language. After the Chinese had banned direct trade by Chinese merchants with Japan, the Portuguese filled this commercial vacuum as intermediaries between China and Japan. The Portuguese bought Chinese silk and sold it to the Japanese in return for Japanese-mined silver; since silver was more highly valued in China, the Portuguese could then use Japanese silver to buy even larger stocks of Chinese silk. However, by 1573—after the Spanish established a trading base in Manila—the Portuguese intermediary trade was trumped by the prime source of incoming silver to China from the Spanish Americas.

Italian Jesuit Matteo Ricci (1552–1610), was the first European allowed into the Forbidden City, taught the Chinese how to construct and play the spinet, translated Chinese texts into Latin and vice versa, and worked closely with his Chinese associate Xu Guangqi (1562–1633) on mathematical work.


Economic impact in Europe
As a wider variety of global luxury commodities entered the European markets by sea, previous European markets for luxury goods stagnated. The Atlantic trade largely supplanted pre-existing Italian and German trading powers which had relied on their Baltic, Russian and Islamic trade links. The new commodities also caused social change, as sugar, spices, silks and chinawares entered the luxury markets of Europe.

The European economic center shifted from the Mediterranean to Western Europe. The city of Antwerp, part of the Duchy of Brabant, became "the center of the entire international economy, and the richest city in Europe at this time. Centered in Antwerp first and then in Amsterdam, "Dutch Golden Age" was tightly linked to the Age of Discovery. Francesco Guicciardini, a Venetian envoy, stated that hundreds of ships would pass Antwerp in a day, and 2,000 carts entered the city each week. Portuguese ships laden with pepper and cinnamon would unload their cargo. With many foreign merchants resident in the city and governed by an oligarchy of banker-aristocrats forbidden to engage in trade, the economy of Antwerp was foreigner-controlled, which made the city very international, with merchants and traders from Venice, Ragusa, Spain and Portugal and a policy of toleration, which attracted a large orthodox Jewish community. The city experienced three booms during its golden age, the first based on the pepper market, a second launched by American silver coming from Seville (ending with the bankruptcy of Spain in 1557), and a third boom, after the Treaty of Cateau-Cambresis, in 1559, based on the textiles industry.

Despite initial hostilities, by 1549 the Portuguese were sending annual trade missions to Shangchuan Island in China. In 1557 they managed to convince the Ming court to agree on a legal port treaty that would establish Macau as an official Portuguese trade colony. The Portuguese friar Gaspar da Cruz (c. 1520 February 5, 1570) wrote the first complete book on China and the Ming Dynasty that was published in Europe; it included information on its geography, provinces, royalty, official class, bureaucracy, shipping, architecture, farming, craftsmanship, merchant affairs, clothing, religious and social customs, music and instruments, writing, education, and justice.

From China the major exports were silk and porcelain, adapted to meet European tastes. The Chinese export porcelains were held in such great esteem in Europe that, in English, china became a commonly–used synonym for porcelain. Kraak porcelain (believed to be named after the Portuguese carracks in which it was transported) was among the first Chinese ware to arrive in Europe in mass quantities. Only the richest could afford these early imports, and Kraak often featured in Dutch still life paintings. Soon the Dutch East India Company established a lively trade with the East, having imported 6 million porcelain items from China to Europe between the years 1602 to 1682. The Chinese workmanship impressed many. Between 1575 and 1587 Medici porcelain from Florence was the first successful attempt to imitate Chinese porcelain. Although Dutch potters did not immediately imitate Chinese porcelain, they began to do it when the supply to Europe was interrupted, after the death of Wanli Emperor in 1620. Kraak, mainly the blue and white porcelain, was imitated all over the world by potters in Arita, Japan and Persia— where Dutch merchants turned when the fall of the Ming Dynasty rendered Chinese originals unavailable—and ultimately in Delftware. Dutch and later English Delftware inspired by Chinese designs persisted from about 1630 to the mid-18th century alongside European patterns.

Antonio de Morga (1559–1636), a Spanish official in Manila, listed an extensive inventory of goods that were traded by Ming China at the turn of the 17th century, noting there were "rarities which, did I refer to them all, I would never finish, nor have sufficient paper for it". After noting the variety of silk goods traded to Europeans, Ebrey writes of the considerable size of commercial transactions: In one case a galleon to the Spanish territories in the New World carried over 50,000 pairs of silk stockings. In return China imported mostly silver from Peruvian and Mexican mines, transported via Manila. Chinese merchants were active in these trading ventures, and many emigrated to such places as the Philippines and Borneo to take advantage of the new commercial opportunities.

The increase in wealth experienced by Spain coincided with a major inflationary cycle both within Spain and Europe, known as price revolution. Spain had amassed large quantities of gold and silver from the New World In the 1520s large scale extraction of silver from Mexico's Guanajuato began. With the opening of the silver mines in Zacatecas and Bolivia's Potosí in 1546 large shipments of silver became the fabled source of wealth. During the 16th century, Spain held the equivalent of US$1.5 trillion (1990 terms) in gold and silver from New Spain. Being the most powerful European monarch at a time full of war and religious conflicts, Philip II squandered wealth in arts and wars across Europe. "I learnt a proverb here", said a French traveler in 1603: "Everything is dear in Spain except silver". The spent silver, suddenly spread throughout a previously cash starved Europe, caused widespread inflation. The inflation was worsened by a growing population but a static production level, low salaries and a rising cost of living. Increasingly Spain became dependent on the revenues flowing in from the mercantile empire in the Americas, leading to Spain's first bankruptcy in 1557 due to rising military costs. Philip II of Spain, defaulted on their debt several times, had to declare four state bankruptcies in 1557, 1560, 1575 and 1596, becoming the first sovereign nation in history to declare bankruptcy. The increase in prices as a result of currency circulation fueled the growth of the commercial middle class in Europe, the bourgeoisie, which came to influence the politics and culture of many countries.



Russians Reach the Pacific

In 1639 a group of explorers led by Ivan Moskvitin became the first Russians to reach the Pacific Ocean and to discover the Sea of Okhotsk, having built a winter camp on its shore at the Ulya River mouth. The Cossacks learned from the locals about the proximity of the Amur River. In 1640 they apparently sailed south, explored the south-eastern shores of the Okhotsk Sea, perhaps reaching the mouth of the Amur River and possibly discovering the Shantar Islands on their way back. Based on Moskvitin's account, Kurbat Ivanov draw the first Russian map of the Far East in 1642.

Baikal Sea Map

In 1643, Vasily Poyarkov crossed the Stanovoy Range and reached the upper Zeya River in the country of the Daurs, who were paying tribute to the Manchu Chinese. After wintering, in 1644 Poyarkov pushed down the Zeya and became the first Russian to reach the Amur River. He sailed down the Amur and finally discovered the mouth of that great river from land. Since his Cossacks provoked the enmity of the locals behind, Poyarkov chose a different way back. They built boats and in 1645 sailed along the Sea of Okhotsk coast to the Ulya River and spent the next winter in the huts that had been built by Ivan Moskvitin six years earlier. In 1646 they returned to Yakutsk.

In 1644 Mikhail Stadukhin discovered the Kolyma River and founded Srednekolymsk. A merchant named Fedot Alekseyev Popov organized a further expedition eastward, and Semyon Dezhnyov became a captain of one of the kochi. In 1648 they sailed from Srednekolymsk down to the Arctic and after some time they rounded Cape Dezhnyov, thus becoming the first explorers to pass through the Bering Strait and to discover Chukotka and the Bering Sea. All their kochi and most of their men (including Popov himself) were lost in storms and clashes with the natives. A small group led by Dezhnyov reached the mouth of the Anadyr River and sailed up it in 1649, having built new boats from the wreckage. They founded Anadyrsk and were stranded there, until Stadukhin found them, coming from Kolyma by land. Subsequetly Stadukhin set off south in 1651 and discovered Penzhin Bay on the northern coast of the Okhotsk Sea. He also may have explored the western shores of Kamchatka.

In 1649–50 Yerofey Khabarov became the second Russian to explore the Amur River. Through Olyokma, Tungur and Shilka Rivers he reached Amur (Dauria), returned to Yakutsk and then back to Amur with a larger force in 1650–53. This time he was met with armed resistance. He built winter quarters at Albazin, then sailed down Amur and found Achansk, which preceded the present-day Khabarovsk, defeating or evading large armies of Daurian Manchu Chinese and Koreans on his way. He charted the Amur in his Draft of the Amur river. Subsequently Russians held on to the Amur Region until 1689, when by the Treaty of Nerchinsk this land was assigned to Chinese Empire (it was returned, however, by the Treaty of Aigun in 1858).

In 1659–65 Kurbat Ivanov was the next head of Anadyrsky ostrog after Semyon Dezhnyov. In 1660 he sailed from Anadyr Bay to Cape Dezhnyov. Atop his earlier pioneering charts, Ivanov is credited with creation of the early map of Chukotka and Bering Strait, which was the first to show on paper (very schematically) the yet undiscovered Wrangel Island, both Diomede Islands and Alaska, based on the data collected from the natives of Chukotka.

So, by the mid-17th century Russians established the borders of their country close to modern ones, and explored almost the whole of Siberia, except the eastern Kamchatka and some regions north of the Arctic Circle. The conquest of Kamchatka later would be achieved in the early 1700-s by Vladimir Atlasov, while the discovery of the Arctic coastline and Alaska would be completed by the Great Northern Expedition in 1733–1743.



Conquest of the Khanate of Sibir

In the mid-16th century the Tsardom of Russia conquered the Tatar khanates of Kazan and Astrakhan, thus annexing the entire Volga Region and opening the way to the Ural Mountains. The colonisation of the new easternmost lands of Russia and further onslaught eastward was led by the rich merchants Stroganovs. Tsar Ivan IV granted vast estates near the Urals as well as tax privileges to Anikey Stroganov, who organized large scale migration to these lands. Stroganovs developed farming, hunting, saltworks, fishing, and ore mining on the Urals and established trade with Siberian tribes.


Around 1577, Semyon Stroganov and other sons of Anikey Stroganov hired a Cossack leader called Yermak to protect their lands from the attacks of Siberian Khan Kuchum. By 1580 Stroganovs and Yermak came up with the idea of the military expedition to Siberia, in order to fight Kuchum in his own land. In 1581 Yermak began his voyage into the depths of Siberia. After a few victories over the khan's army, Yermak's people defeated the main forces of Kuchum on Irtysh River in a 3-day Battle of Chuvash Cape in 1582. The remains of the khan's army retreated to the steppes, and thus Yermak captured the Siberia Khanate, including its capital Qashliq near modern Tobolsk. Kuchum still was strong and suddenly attacked Yermak in 1585 in the dead of night, killing most of his people. Yermak was wounded and tried to swim across the Wagay River (Irtysh's tributary), but drowned under the weight of his own chain mail. The Cossacks had to withdraw from Siberia completely, but thanks to Yermak's having explored all the main river routes in West Siberia, Russians successfully reclaimed all his conquests just several years later.


Siberian river routes
In the early 17th century the eastward movement of Russians was slowed by the internal problems in the country during the Time of Troubles. However, very soon the exploration and colonization of the huge territories of Siberia was resumed, led mostly by Cossacks hunting for valuable furs and ivory. While Cossacks came from the Southern Urals, another wave of Russians came by the Arctic Ocean. These were Pomors from the Russian North, who already had been making fur trade with Mangazeya in the north of the Western Siberia for quite a long time. In 1607 the settlement of Turukhansk was founded on the northern Yenisey River, near the mouth of Lower Tunguska, and in 1619 Yeniseysky ostrog was founded on the mid-Yenisey at the mouth of the Upper Tunguska.

Between 1620-1624 a group of fur hunters led by Demid Pyanda left Turukhansk and explored some 1,430 miles (2,300 km) of the Lower Tunguska, wintering in the proximity of the Vilyuy and Lena rivers. According to later legendary accounts (folktales collected a century after the fact), Pyanda discovered the Lena River. He allegedly explored some 1,500 miles (2,400 km) of its length, reaching as far as central Yakutia. He returned back up the Lena until it became too rocky and shallow, and portaged to the Angara. In this way, Pyanda may have become the first Russian to meet Yakuts and Buryats. He built new boats and explored some 870 miles (1,400 km) of the Angara, finally reaching Yeniseysk and discovering that the Angara (a Buryat name) and Upper Tunguska (Verkhnyaya Tunguska, as initially known by Russians) are one and the same river.

In 1627 Pyotr Beketov was appointed Yenisey voevoda in Siberia. He successfully carried out the voyage to collect taxes from Zabaykalye Buryats, becoming the first Russian to step in Buryatia. He founded the first Russian settlement there, Rybinsky ostrog. Beketov was sent to the Lena River in 1631, where in 1632 he founded Yakutsk and sent his Cossacks to explore the Aldan and farther down the Lena, to found new fortresses, and to collect taxes.

Yakutsk soon turned into a major starting point for further Russian expeditions eastward, southward and northward. Maksim Perfilyev, who earlier had been one of the founders of Yeniseysk, founded Bratsky ostrog on the Angara in 1631, and in 1638 he became the first Russian to step into Transbaikalia, travelling there from Yakutsk.
In 1643 Kurbat Ivanov led a group of Cossacks from Yakutsk to the south of the Baikal Mountains and discovered Lake Baikal, visiting its Olkhon Island. Later Ivanov made the first chart and description of Baikal.



Dutch, Australia and New Zealand

 Tasman Routes
Terra Australis Ignota (Latin, "the unknown land of the south") was a hypothetical continent appearing on European maps from the 15th to the 18th centuries, with roots in a notion introduced by Aristotle. It was depicted on the mid-16th-century Dieppe maps, where its coastline appeared just south of the islands of the East Indies; it was often elaborately charted, with a wealth of fictitious detail. The discoveries reduced the area where the continent could be found; however, many cartographers held to Aristotle's opinion, like Gerardus Mercator (1569) and Alexander Dalrymple even so late as 1767 argued for its existence, with such arguments as that there should be a large landmass in the south as a counterweight to the known landmasses in the Northern Hemisphere. As new lands were discovered, they were often assumed to be parts of this hypothetical continent.

Juan Fernandez, sailing from Chile in 1576, claimed he had discovered the Southern Continent. Luis Váez de Torres, a Galician navigator working for the Spanish Crown, proved the existence of a passage south of New Guinea, now known as Torres Strait. Pedro Fernandes de Queirós, a Portuguese navigator sailing for the Spanish Crown, saw a large island south of New Guinea in 1606, which he named La Australia del Espiritu Santo. He represented this to the King of Spain as the Terra Australis incognita.

Duyfken replica, Swan River, Australia

Dutch navigator and colonial governor, Willem Janszoon was the first European known to have seen the coast of Australia. Janszoon sailed from the Netherlands for the East Indies for the third time on December 18, 1603, as captain of the Duyfken (or Duijfken, meaning "Little Dove"), one of twelve ships of the great fleet of Steven van der Hagen. Once in the Indies, Janszoon was sent to search for other outlets of trade, particularly in "the great land of Nova Guinea and other East and Southlands." On November 18, 1605, the Duyfken sailed from Bantam to the coast of western New Guinea. Janszoon then crossed the eastern end of the Arafura Sea, without seeing the Torres Strait, into the Gulf of Carpentaria. On February 26, 1606, he made landfall at the Pennefather River on the western shore of Cape York in Queensland, near the modern town of Weipa. This is the first recorded European landfall on the Australian continent. Janszoon proceeded to chart some 320 km of the coastline, which he thought was a southerly extension of New Guinea. In 1615, Jacob le Maire and Willem Schouten's rounding of Cape Horn proved that Tierra del Fuego was a relatively small island.

In 1642–1644 Abel Tasman, also a Dutch explorer and merchant in the service of the VOC, circumnavigated New Holland proving that Australia was not part of the mythical southern continent. He was the first known European expedition to reach the islands of Van Diemen's Land (now Tasmania) and New Zealand and to sight the Fiji islands, which he did in 1643. Tasman, his navigator Visscher, and his merchant Gilsemans also mapped substantial portions of Australia, New Zealand and the Pacific Islands.



Barentsz' Arctic Exploration

5 June 1594, Dutch cartographer Willem Barentsz departed from Texel in a fleet of three ships to enter the Kara Sea, with the hopes of finding the Northeast passage above Siberia. At Williams Island the crew encountered a polar bear for the first time. They managed to bring it on board, but the bear rampaged and was killed. Barentsz reached the west coast of Novaya Zemlya and followed it northward, before being forced to turn back in the face of large icebergs.

The following year, Prince Maurice of Orange named him Chief Pilot of a new expedition of six ships, loaded with merchant wares that the Dutch hoped to trade with China. The party came across Samoyed "wild men" but eventually turned back upon discovering the Kara Sea frozen. In 1596, the States-General offered a high reward for anybody who successfully navigated the Northeast Passage. The Town Council of Amsterdam purchased and outfitted two small ships, captained by Jan Rijp and Jacob van Heemskerk, to search for the elusive channel, under the command of Barents. They set off on May, and on June discovered Bear Island and Spitsbergen, sighting its northwest coast. They saw a large bay, later called Raudfjorden and entered Magdalenefjorden, which they named Tusk Bay, sailing into the northern entrance of Forlandsundet, which they called Keerwyck, but were forced to turn back because of a shoal. On 28 June they rounded the northern point of Prins Karls Forland, which they named Vogelhoek, on account of the large number of birds, and sailed south, passing Isfjorden and Bellsund, which were labelled on Barentsz's chart as Grooten Inwyck and Inwyck.

The ships once again reached Bear Island on 1 July, which led to a disagreement. They parted ways, with Barentsz continuing northeast, while Rijp headed north. Barentsz reached Novaya Zemlya and, to avoid becoming entrapped in ice, headed for the Vaigatch Strait but became stuck within the icebergs and floes. Stranded, the 16-man crew was forced to spend the winter on the ice. The crew used lumber from their ship to build a lodge they called Het Behouden Huys (The Kept House). Dealing with extreme cold, they used the merchant fabrics to make additional blankets and clothing and caught arctic foxes in primitive traps, as well as polar bears. When June arrived, and the ice had still not loosened its grip on the ship, scurvy-ridden survivors took two small boats out into the sea. Barentsz died at sea on 20 June 1597, while studying charts. It took seven more weeks for the boats to reach Kola where they were rescued by a Russian merchant vessel. Only 12 crewmen remained, reaching Amsterdam in November two of Barentsz' crewmembers later published their journals, Jan Huyghen van Linschoten, who had accompanied him on the first two voyages, and Gerrit de Veer who had acted as the ship's carpenter on the last.

In 1608, Henry Hudson made a second attempt, trying to go across the top of Russia. He made it to Novaya Zemlya but was forced to turn back. Between 1609–1611, Hudson, after several voyages on behalf of English merchants to explore a prospective Northern Sea Route to India, explored the region around modern New York City while looking for a western route to Asia under the auspices of the Dutch East India Company (VOC).



Search for a Northern Route

France, the Netherlands, and England were left without a sea route to Asia, either via Africa or South America. When it became apparent that there was no route through the heart of the American continent, attention turned to the possibility of a passage through northern waters, which English called the Northwest Passage. The desire to establish such a route motivated much of the European exploration of both coasts of North America and in Russia. In Russia the idea of a possible seaway connecting the Atlantic and the Pacific was first put forward by the diplomat Gerasimov in 1525, although Russian settlers on the coast of the White Sea, the Pomors, had been exploring parts of the route as early as the 11th century.


In 1553 English explorer Hugh Willoughby with chief pilot Richard Chancellor were sent out with three vessels in search of a passage by London's Company of Merchant Adventurers to New Lands. During the voyage across the Barents Sea, Willoughby thought he saw islands to the north, and islands called Willoughby's Land were shown on maps published by Plancius and Mercator into the 1640s. The vessels were separated by "terrible whirlwinds" in the Norwegian Sea and Willoughby sailed into a bay near the present border between Finland and Russia. His ships with the frozen crews, including Captain Willoughby and his journal, were found by Russian fishermen a year later. Richard Chancellor was able to drop anchor in the White Sea and trudge his way overland to Moscow and Ivan the Terrible's Court, opening trade with Russia and the Company of Merchant Adventurers became the Muscovy Company.



Exploring North America

The 1497 English expedition led by John Cabot was the first of a series of French and English missions exploring North America. Spain put limited efforts into exploring the northern part of the Americas, as its resources were concentrated in Central and South America where more wealth had been found. These expeditions were hoping to find an oceanic Northwest Passage to Asian trade. This was never discovered, but other possibilities were found and in the early 17th century colonists from a number of Northern European states began to settle on the east coast of North America.

In 1524, Giovanni da Verrazzano, an Italian sailing at the service of king Francis I of France- who was motivated by the "insolence" of the division of the world between the Portuguese and the Spanish- made the first recorded European to visit the Atlantic Coast of the present-day United States, having explored the coast from South Carolina to Nova Scotia, and islands such as Newfoundland. In the same year Estevão Gomes, a Portuguese cartographer who had sailed in the fleet of Ferdinand Magellan, explored Nova Scotia province sailing South through Maine, where he entered New York Harbor, the Hudson River and eventually reached Florida in August 1525. As a result of his expedition, the 1529 Diogo Ribeiro world map outlines the East coast of North America almost perfectly. From 1534 to 1536 French explorer Jacques Cartier, believed to have accompanied da Verrazzano to Nova Scotia and Brazil, was the first European to travel inland in North America, describing the Gulf of Saint Lawrence, which he named "The Country of Canadas", after Iroquois names, claiming what is now Canada for Francis I of France.

Europeans explored the Pacific Coast beginning in the mid- 16th century. Francisco de Ulloa explored the Pacific coast of present-day Mexico including the Gulf of California, proving that Baja California was a peninsula  but in spite of his discoveries the myth persisted in Europe that California was an island. His account provided the first recorded use of the name "California". João Rodrigues Cabrilho, a Portuguese navigator sailing for the Spanish Crown, was the first European to set foot in California, landing on September 28, 1542 on the shores of San Diego Bay and claiming California for Spain. He also landed on San Miguel, one of the Channel Islands, and continued as far as Point Reyes. After his death the crew continued exploring as far north as Oregon.

The English Francis Drake sailed along the coast in 1579 somewhere north of Cabrillo's landing site—the actual location of Drake's landing was secret and is still undetermined—and claimed the land for England, calling it Nova Albion. The term "Nova Albion" was therefore used on many European maps to designate territory north of the Spanish settlements.

Between 1609–1611, English Henry Hudson, after several voyages on behalf of English merchants to explore a prospective Northeast Passage to India, explored the region around modern New York City while looking for a western route to Asia under the auspices of the Dutch East India Company (VOC). He explored the Hudson River and laid the foundation for Dutch colonization of the region. Hudson's final expedition ranged farther north in search of the Northwest Passage, leading to his discovery of the Hudson Strait and Hudson Bay. After wintering in the James Bay, Hudson tried to press on with his voyage in the spring of 1611, but his crew mutinied and they cast him adrift.



New Trade Routes (1542–1565)

Portuguese Trade Route

In 1543 three Portuguese traders, accidentally became the first Westerners to reach and trade with Japan. According Fernão Mendes Pinto, who claimed to be in this journey, they arrived at Tanegashima, where the locals were impressed by firearms, that would be immediately made by the Japanese on a large scale.

The Spanish conquest of the Philippines was ordered by Philip II of Spain, and Andrés de Urdaneta was the designated commander. Urdaneta agreed to accompany the expedition but refused to command and Miguel López de Legazpi was appointed instead. The expedition set sail on November 1564. After spending some time on the islands, Legazpi sent Urdaneta back to find a better return route. Urdaneta set sail from San Miguel on the island of Cebu on June 1, 1565, but was obliged to sail as far as 38 degrees North latitude to obtain favourable winds.

He reasoned that the trade winds of the Pacific might move in a gyre as the Atlantic winds did. If in the Atlantic, ships made the Volta do mar to pick up winds that would bring them back from Madeira, then, he reasoned, by sailing far to the north before heading east, he would pick up trade winds to bring him back to North America. His hunch paid off, and he hit the coast near Cape Mendocino, California, then followed the coast south. The ship reached the port of Acapulco, on October 8, 1565, having traveled 12,000 miles (20,000 km) in 130 days. Fourteen of his crew died; only Urdaneta and Felipe de Salcedo, nephew of López de Legazpi, had strength enough to cast the anchors.

Thus, a cross-Pacific Spanish route was established, between Mexico and the Philippines. For a long time these routes were used by the Manila galleons, thereby creating a trade link joining China, the Americas, and Europe via the combined trans-Pacific and trans-Atlantic routes.



Pizarro's Peru And The Inca Empire

A first attempt to explore western South America was undertaken in 1522 by Pascual de Andagoya. Native South Americans told him about a gold-rich territory on a river called Pirú. Having reached San Juan River (Colombia), Andagoya fell ill and returned to Panama, were he spread news about "Pirú" as the legendary El Dorado. These, along with the accounts of success of Hernán Cortés, caught the attention of Pizarro.

Francisco Pizarro had accompanied Balboa in the crossing of the Isthmus of Panama. In 1524 he formed a partnership with priest Hernando de Luque and soldier Diego de Almagro to explore the south, agreeing to divide the profits. They dubbed the enterprise the "Empresa del Levante": Pizarro would command, Almagro would provide military and food supplies, and Luque would be in charge of finances and additional provisions.

On 13 September 1524, the first of three expeditions left to conquest Peru with about 80 men and 40 horses. The expedition was a failure, reaching no farther than Colombia before succumbing to bad weather, hunger and skirmishes with hostile locals, were Almagro lost an eye. The place names bestowed along their route, Puerto deseado (desired port), Puerto del hambre (port of hunger) and Puerto quemado (burned port), testify these difficulties. Two years later they proceed in a second expedition with reluctant permission from Panama Governor. In August 1526, they left with two ships, 160 men and several horses. Upon reaching San Juan River they separated, Pizarro staying to explore the swampy coasts and Almagro sent back for reinforcements. Pizarro's main pilot sailed south and, after crossing the equator captured a raft from Tumbes. To his surprise, it carried textiles, ceramic and much-desired gold, silver, and emeralds, becoming the central focus of the expedition. Soon Almagro joined with reinforcements and they resumed. After a difficult voyage facing strong winds and currents, they reached Atacames were they found a large native population under Inca rule, but they seemed so dangerous that they didn't enter land.

Pizarro stood at safe near the coast, while Almagro and Luque went back for reinforcements with proof of the found gold. The new governor outright rejected a third expedition and ordered two ships to bring everyone back to Panama. Almagro and Luque grasped the opportunity to join Pizarro. When they arrived at the Isla de Gallo, Pizarro drew a line in the sand, saying: "There lies Peru with its riches; Here, Panama and its poverty. Choose, each man, what best becomes a brave Castilian." Thirteen men decided to stay and became known as The Famous Thirteen. They headed for La Isla Gorgona, where they remained for seven months before the arrival of provisions.

They decided to sail south and, by April 1528, reached the northwestern Peruvian Tumbes Region and were warmly received by local Tumpis. Two of Pizarro's men reported incredible riches, including gold and silver decorations around the chief's house. They saw for the first time a Llama which Pizarro called "little camels". The natives named the Spanish "Children of the Sun" for their fair complexion and brilliant armors. They decided then to return to Panama to prepare a final expedition. Before leaving they sailed south through territories they named such as Cabo Blanco, port of Payta, Sechura, Punta de Aguja, Santa Cruz, and Trujillo, reaching the ninth degree south.

In the spring of 1528 Pizarro sailed for Spain, were he had an interview with king Charles I. The king heard of his expeditions in lands rich in gold and silver and promised to support him. The Capitulación de Toledo authorized Pizarro to proceed with the conquest of Peru. Pizarro convinced then many friends and relatives to join: his brothers Hernándo Pizarro, Juan Pizarro, Gonzalo Pizarro and also Francisco de Orellana, who would later explore the Amazon River, as well as his cousin Pedro Pizarro.

Pizarro's third and final expedition left Panama for Peru on 27 December 1530. With three ships and one hundred and eighty men they landed near Ecuador and sailed to Tumbes, finding the place destroyed. They entered the interior and established the first Spanish settlement in Peru, San Miguel de Piura. One of the men returned with an Incan envoy and an invitation for a meeting. Inca were at a civil war and Atahualpa had been resting in northern Peru following the defeat of his brother Huascar. After marching for two months, they approached Atahualpa. He, however, refused the Spanish by saying he would "be no man's tributary." There were fewer than 200 Spanish to his 80,000 soldiers, but Pizarro attacked and won the Incan army in the Battle of Cajamarca, taking Atahualpa captive at the so-called ransom room. Despite fulfilling his promise of filling one room with gold and two with silver, he was convicted for killing his brother and plotting against Pizarro, and was executed.

In 1533, Pizarro invaded Cuzco with indigenous troops and wrote to the king Charles I: "This city is the greatest and the finest ever seen in this country or anywhere in the Indies... it is so beautiful and has such fine buildings that it would be remarkable even in Spain." After the Spanish had sealed the conquest of Peru, Jauja in fertile Mantaro Valley was established as Peru's provisional capital, but it was too far up in the mountains that Pizarro thus founded the city of Lima on 18 January 1535, considered by himself one of the most important acts in his life.



Mexico And The Aztec Empire

Rumors of undiscovered islands northwest of Hispaniola had reached Spain by 1511 and king Ferdinand II of Aragon was interested in forestalling further exploration. While Portuguese were making huge gains in the Indian Ocean, the Spanish invested in exploring inland in search of gold and valuable resources. The members of these expeditions, the "conquistadors", came from a variety of backgrounds including artisans, merchants, clergy, lesser nobility and freed slaves. They usually supplied their own equipment in exchange for a share in profits, having no direct connection with the royal army, and often no professional military training or experience.


In the Americas the Spanish found a number of empires that were as large and populous as those in Europe. However, small bodies of conquistadors, with large armies of indigenous Americans groups, managed to conquer these states. During this time, pandemics of European disease such as smallpox devastated the indigenous populations. Once Spanish sovereignty was established, the Spanish focused on the extraction and export of gold and silver.

In 1512, to reward Juan Ponce de León for exploring Puerto Rico in 1508, king Ferdinand urged him to seek these new lands. He would become governor of discovered lands, but was to finance himself all exploration. With three ships and about 200 men, Léon set out from Puerto Rico on March 1513. In April they sighted land and named it La Florida—because it was Easter (Florida) season—believing it was an island, becoming credited as the first European to land in the continent. The arrival location has been disputed between St. Augustine, Ponce de León Inlet and Melbourne Beach. They headed south for further exploration and on April 8 encountered a current so strong that it pushed them backwards: this was the first encounter with the Gulf Stream that would soon become the primary route for eastbound ships leaving the Spanish Indies bound for Europe. They explored down the coast reaching Biscayne Bay, Dry Tortugas and then sailing southwest in an attempt to circle Cuba to return, reaching Grand Bahama on July.

In 1517 Cuba's governor Diego Velázquez de Cuéllar commissioned a fleet under the command of Hernández de Córdoba to explore the Yucatán peninsula. They reached the coast where Mayans invited them to land, but were attacked at night and only a remnant of the crew returned. Velázquez then commissioned another expedition led by his nephew Juan de Grijalva, who sailed south along the coast to Tabasco, part of the Aztec empire. In 1518 Velázquez gave the mayor of the capital of Cuba, Hernán Cortés, the command of an expedition to secure the interior of Mexico but, due to an old gripe between them, revoked the charter.

In February 1519 Cortés went ahead anyway, in an act of open mutiny. With about 11 ships, 500 men, 13 horses and a small number of cannons he landed in Yucatán, in Mayan territory, claiming the land for the Spanish crown. From Trinidad he proceeded to Tabasco and won a battle against the natives. Among the vanquished was La Malinche, his future mistress, who knew both (Aztec) Nahuatl language and Maya, becoming a valuable interpreter and counselor. Through her, Cortés learned about the wealthy Aztec Empire.

In July his men took over Veracruz and he placed himself under direct orders of new king Charles V of Spain. There Cortés asked for a meeting with Aztec Emperor Moctezuma II, who repeatedly refused. They headed to Tenochtitlan and on the way made alliances with several tribes. In October, accompanied by about 3,000 Tlaxcaltec they marched to Cholula, the second largest city in central Mexico. Either to instill fear upon the Aztecs waiting for him or (as he later claimed) wishing to make an example when he feared native treachery, they massacred thousands of unarmed members of the nobility gathered at the central plaza and partially burned the city.

Arriving in Tenochtitlan with a large army, on November 8 they were peacefully received by Moctezuma II, who deliberately let Cortés enter the heart of the Aztec Empire, hoping to know them better to crush them later. The emperor gave them lavish gifts in gold which enticed them to plunder vast amounts. In his letters to Charles V, Cortés claimed to have learned then that he was considered by the Aztecs to be either an emissary of the feathered serpent god Quetzalcoatl or Quetzalcoatl himself—a belief contested by a few modern historians. But he soon learned that his men on the coast had been attacked, and decided to hostage Moctezuma in his palace, demanding a ransom as tribute to Charles V.

Meanwhile, Velasquez sent another expedition, led by Pánfilo de Narváez, to oppose Cortès, arriving in Mexico in April 1520 with 1,100 men. Cortés left 200 men in Tenochtitlan and took the rest to confront Narvaez, whom he overcame, convincing his men to join him. In Tenochtitlán one of Cortés's lieutenants committed a massacre in the Main Temple, triggering local rebellion. Cortés speedily returned, attempting the support of Moctezuma but the Aztec emperor was killed, possibly stoned by his subjects. The Spanish fled for the Tlaxcaltec during the Noche Triste, where they managed a narrow escape while their backguard was massacred. Much of the treasure looted was lost during this panicked escape. After a battle in Otumba they reached Tlaxcala, having lost 870 men. Having prevailed with the assistance of allies and reinforcements from Cuba, Cortés sieged of Tenochtitlán and captured its ruler Cuauhtémoc on August 1521. As the Aztec Empire ended he claimed the city for Spain, renaming it Mexico City.



Westward and Eastward Exploration Met


Soon after Magellan's expedition the Portuguese rushed to seize the surviving Spaniards and build a fort in Ternate. In 1525, Charles I of Spain sent another expedition sailing westwards led by García Jofre de Loaísa to colonize the Maluku Islands, claiming that they were in his zone of the Treaty of Tordesillas. The fleet of seven ships and 450 men included the most notable Spanish navigators: Juan Sebastián Elcano and Loaísa, who lost their lives there, and the young Andrés de Urdaneta. Near the Strait of Magellan one of the ships was pushed south by a storm, reaching 56 ° S, where they thought seeing "earth's end": so the Cape Horn was crossed the first time. The expedition reached the islands with great difficulty, docking at Tidore. The conflict with the Portuguese already established in nearby Ternate was inevitable, starting nearly a decade of skirmishes.

As there was not a set eastern Tordesillas limit, both kingdoms organized meetings to resolve the issue. From 1524 to 1529 Portuguese and Spanish experts met at Badajoz-Elvas trying to find the exact location of the antimeridian of Tordesillas, which would divide the world into two equal hemispheres. Each crown appointed three astronomers and cartographers, three pilots and three mathematicians. Lopo Homem, Portuguese cartographer and cosmographer was in the board, along with cartographer Diogo Ribeiro on the Spanish delegation. The board met several times, without reaching an agreement: the knowledge at that time was insufficient for an accurate calculation of longitude, and each group gave the islands to its sovereign. The issue was settled only in 1529, after a long negotiation, with the signing of Treaty of Zaragoza, that attributed the Maluku Islands to Portugal and the Philippines to Spain.

Between 1525 and 1528 Portugal had sent several expeditions around the Maluku Islands. Gomes de Sequeira and Diogo da Rocha were sent north by the governor of Ternate Jorge de Meneses, being the first Europeans to reach the Caroline Islands, which they named "Islands de Sequeira". In 1526, Jorge de Meneses docked on Waigeo island, Papua New Guinea. Based on these explorations stands the theory of Portuguese discovery of Australia, one among several competing theories about the early discovery of Australia, supported by Australian historian Kenneth McIntyre, stating it was discovered by Cristóvão de Mendonça and Gomes de Sequeira.


In 1527 Hernán Cortés fitted out a fleet of three ships to find new land in the "South Sea" (Pacific Ocean) and asked his cousin Alvaro de Saavedra to take charge. On October 31 of 1527 Saavedra sailed from New Spain, crossing the Pacific and touring the north of New Guinea then named Isla de Oro. In October 1528 one of the vessels reached Maluku Islands. In his attempt to return to New Spain he was diverted by the northeast trade winds, which threw him back so he tried sailing back down, to the south. He returned to New Guinea and turned to the northeast, where he sighted groups of the Marshall Islands and the Admiralty Islands and again was surprised by the winds, which brought him a third time to the Moluccas. The westbound return route was harder to find, but was eventually discovered by Andrés de Urdaneta in 1565.



First Circumnavigation


In 1513, about 40 miles south of Acandí, in present day Colombia, Spanish Vasco Núñez de Balboa heard unexpected news of an "other sea" rich in gold, which he received with great interest. With few resources and using information given by caciques, he journeyed across the Isthmus of Panama with 190 Spaniards, a few native guides, and a pack of dogs. Using a small brigantine and ten native canoes, they sailed along the coast and made landfall. On September 6, the expedition was reinforced with 1,000 men, fought several battles, entered a dense jungle and climbed the mountain range along the Chucunaque River from were this "other sea" could be seen. Balboa went ahead and, before noon September 25, he saw in the horizon an undiscovered sea, becoming the first European to have seen or reached the Pacific from the New World. The expedition descended towards the shore for a short reconnaissance trip, thus becoming the first Europeans to navigate the Pacific Ocean. After traveling more than 110 km (68 mi), Balboa named the bay where they ended up San Miguel. He named the new sea Mar del Sur (South Sea), since they had traveled south to reach it. Balboa's main purpose in the expedition was the search for gold-rich kingdoms. To this end, he crossed through the lands of caciques to the islands, naming the largest one Isla Rica (Rich Island, today known as Isla del Rey). He named the entire group Archipiélago de las Perlas, which they still keep today. In 1515–1516 Juan Díaz de Solís sailed as far as Río de la Plata, which he named, having died trying to find a passage to the "South Sea" in South America at the service of Spain.

Since 1516, several Portuguese conflicting with king Manuel I of Portugal gathered in Seville, at the service of the newly crowned Charles I of Spain. Among them were explorers Diogo and Duarte Barbosa, Estevão Gomes, João Serrão and Ferdinand Magellan, the cartographers Jorge Reinel and Diogo Ribeiro, the cosmographers Francisco and Ruy Faleiro and the Flemish merchant Christopher de Haro. Ferdinand Magellan—who had sailed in India for Portugal until 1513, when Maluku Islands were reached, and kept contact with Francisco Serrão living there—developed the theory that the islands were in the Tordesillas Spanish area, supported on studies by Faleiro brothers. Aware of the efforts of the Spanish to find a route to India by sailing west, Magellan presented them a plan to get there.

The Spanish king and Christopher de Haro financed Magellan's expedition. On August 10, 1519, departed from Seville a fleet of five ships—flagship Trinidad under Magellan's command, San Antonio, Concepcion, Santiago and Victoria, the first being a caravel, and all others rated as carracks or "naus"—with a crew of about 237 men from several nations, with the goal of reaching the Maluku Islands by traveling west, trying to reclaim it under Spain's economic and political sphere.

Victoria, the single ship to have completed the first world circumnavigation.

The fleet sailed further and further south, avoiding the Portuguese territories in Brazil, and become the first to reach Tierra del Fuego at the tip of the Americas. On October 21, starting in Cape Virgenes, began an arduous trip through a 373-mile (600 km) long strait that Magellan named Estrecho de Todos los Santos, modern Strait of Magellan. On November 28, three ships entered the Pacific Ocean—then named Mar Pacífico because of its apparent stillness. The expedition managed to cross the Pacific. Magellan died in the battle of Mactan in the Philippines, leaving the Spaniard Juan Sebastián Elcano the task of completing the voyage, reaching the Spice Islands in 1521. On September 6, 1522 Victoria returned to Spain, thus completing the first circumnavigation of the globe. Of the men who set out on five ships, only 18 completed the circumnavigation and managed to return to Spain in this single vessel led by Elcano. Seventeen other arrived later in Spain: twelve captured by the Portuguese in Cape Verde some weeks earlier and between 1525–1527, and five survivors of the Trinidad. Antonio Pigafetta, a Venetian scholar and traveler who had asked to be on board and become a strict assistant of Magellan, kept an accurate journal that become the main source for much of what we know about this voyage.

This round-the-world voyage gave Spain valuable knowledge of the world and its oceans which later helped in the exploration and settlement of the Philippines. Although this was not a realistic alternative to the Portuguese route around Africa (the Strait of Magellan was too far south, and the Pacific Ocean too vast to cover in a single trip from Spain) successive Spanish expeditions used this information to travel from the Mexican coast via Guam to Manila.



The "Spice Islands" And China

In 1511 Afonso de Albuquerque conquered Malacca to Portugal, then the center of Asian trade. East of Malacca, Albuquerque sent several diplomatic missions: Duarte Fernandes as the first European envoy to the kingdom of Siam (modern Thailand).

Getting to know the secret location of the so-called "spice islands"—the Maluku Islands, mainly the Banda, then the single world source of nutmeg and cloves, main purpose for the travels in the Indian sea- he sent an expedition led by António de Abreu to Banda, where they were the first Europeans to arrive in early 1512. Abreu then left for Ambon Island while his vice-captain Francisco Serrão sank off Ternate, where he obtained a license to build a Portuguese fortress-factory: the Fort of São João Baptista de Ternate, which founded the Portuguese presence in the Malay Archipelago.

In May 1513 Jorge Álvares, one of the Portuguese envoys, reached China. Although he was the first to land on Lintin Island in the Pearl River Delta, it was Rafael Perestrello—a cousin of the famed Christopher Columbus—who became the first European explorer to land on the southern coast of mainland China and trade in Guangzhou in 1516, commanding a Portuguese vessel with a crew from a Malaysian junk that had sailed from Malacca. Fernão Pires de Andrade visited Canton in 1517 and opened up trade with China, in 1557 the Portuguese were permitted to occupy Macau.

To enforce a trade monopoly, Hormuz in the Persian Gulf was seized by Afonso de Albuquerque in 1507 and 1515, who also entered into diplomatic relations with Persia. In 1513 while trying to conquer Aden, an expedition led by Albuquerque cruised the Red Sea inside the Bab al-Mandab, and sheltered at Kamaran island. In 1521, a force under Antonio Correia conquered Bahrain ushering in a period of almost eighty years of Portuguese rule of the Gulf archipelago. In the Red Sea, Massawa was the most northerly point frequented by the Portuguese until 1541, when a fleet under Estevão da Gama penetrated as far as Suez.
