(red) and
Venetian (green) maritime trade routes in the Mediterranean and
Black Sea From the 8th until the 15th century, the
Republic of Venice and neighboring
maritime republics held the monopoly of European trade with the Middle East. The
silk and
spice trade, involving spices,
incense, herbs, drugs, and
opium, made these Mediterranean city-states phenomenally rich. Spices were among the most expensive and demanded products of the Middle Ages, as they were used in
medieval medicine, religious rituals, cosmetics, perfumery, and food additives and preservatives. They were imported from Asia and Africa. Muslim traders dominated maritime routes throughout the Indian Ocean, tapping source regions in the
Far East and shipping for trading emporiums in India, mainly
Calicut, westward to
Hormuz in the
Persian Gulf and
Jeddah in the
Red Sea. From there, overland routes led to the Mediterranean. Afterwards, the routes into Asia through the Black Sea and through Armenia and Persia became blocked by wars and banditry as the Mongol states disintegrated. The trade route from the Persian Gulf to the Mediterranean by land is also dangerous due to the unstable territorial control of the Mamluk. The trade from India went almost entirely into the Red Sea. Nevertheless, European spices have not become more expensive as a result. Forced to reduce activity in the Black Sea, and at war with Venice, the
Genoese had turned to North African trade of wheat, olive oil and a search for silver and gold. Europeans had a constant
deficit in silver and gold, as it only went out, spent on eastern trade now cut off. Several European mines were exhausted, The lack of
bullion led to the development of a complex banking system to manage the risks in trade (the first state bank,
Banco di San Giorgio, was founded in 1407 at Genoa). Sailing into the ports of
Bruges and England, Genoese communities were then established in Portugal, who profited from their enterprise and financial expertise. European sailing had been primarily close to land
cabotage, guided by
portolan charts. These charts specified proven ocean routes guided by coastal landmarks: sailors departed from a known point, followed a compass heading, and tried to identify their location by its landmarks. For the first oceanic exploration Europeans used the compass, and advances in
cartography and astronomy. Arab navigational tools like the
astrolabe and
quadrant were used for
celestial navigation. The Muslim lands in Asia were more economically developed, had better infrastructure, despite Europe's economic changes brought by the
Black Death, allowing for more freedoms. The Islamic
gunpowder empires concealed knowledge from European Christian traders about where lucrative locations such as
Indonesia were. Outbreaks of
bubonic plague led to depopulation in the second half of the 14th century: only the sea offered alternatives, with most population settling in fishing and trading coastal areas. Between 1325 and 1357,
Afonso IV of Portugal encouraged maritime commerce and ordered the first explorations. The
Canary Islands, already known to the Genoese, were claimed as officially discovered under the patronage of the Portuguese, but in 1344 Castile disputed them. To ensure their trade monopoly, Europeans, beginning with the Portuguese, attempted to install a Mediterranean system of trade which used military intimidation, to divert trade through ports they controlled; there it could be taxed. In 1415,
Ceuta, in North Africa, was
conquered by the Portuguese aiming to control navigation of the African coast. Young prince
Henry the Navigator became aware of profit possibilities in the
trans-Saharan trade routes. For centuries
slave and gold trade routes linking West Africa with the Mediterranean passed over the Western Sahara Desert, controlled by the Moors. Henry wished to know how far Muslim territories in Africa extended, hoping to bypass them and trade directly with West Africa by sea, find allies in legendary Christian lands like the supposed long-lost kingdom of
Prester John and probe whether it was possible to reach the
Indies by sea, the source of the lucrative
spice trade. He invested in sponsoring voyages down the coast of
Mauritania, gathering merchants, shipowners and stakeholders interested in new sea lanes. Soon the Atlantic islands of
Madeira (1419) and the
Azores (1427) were reached. The expedition leader who established settlements on Madeira, was explorer
João Gonçalves Zarco. Europeans did not know what lay beyond Cape Non (
Cape Chaunar) on the African coast, and whether it was possible to return once crossed. Nautical myths warned of monsters or an edge of the world, but Henry's navigation challenged such beliefs: starting in 1421, systematic sailing overcame it, reaching the difficult
Cape Bojador that in 1434 one of Henry's captains,
Gil Eanes, finally passed. From 1440,
caravels were extensively used for the exploration of the coast of Africa. This was an Iberian ship type, used for fishing, commerce and military purposes. It had a sternpost-mounted rudder, a shallow draft helpful in exploring coastlines, a good sailing performance, with a
windward ability. The lateen rig was less useful when sailing downwind – which explains
Christopher Columbus () re-rigging the with
square rig. For
celestial navigation the Portuguese used the
ephemerides, which experienced a remarkable diffusion in the 15th century. These were astronomical charts plotting the location of the stars. Published in 1496 by Jewish astronomer and mathematician
Abraham Zacuto, the Almanac Perpetuum included some of these tables for the movements of stars. These revolutionized navigation, allowing the calculation of
latitude. Exact
longitude remained elusive from mariners for centuries. Using the caravel, systematic exploration continued southerly, advancing one degree a year.
Senegal and
Cape Verde Peninsula were reached in 1445 and in 1446,
Álvaro Fernandes pushed on almost as far as present-day
Sierra Leone. In 1453, the
fall of Constantinople to the
Ottomans was a perceived blow to Christendom and established business links with the East. In 1455,
Pope Nicholas V issued the
bull Romanus Pontifex reinforcing the
Dum Diversas (1452), granting all lands and seas discovered beyond Cape Bojador to King
Afonso V of Portugal and successors, as well as cutting off trade to and permitting increased war against Muslims and pagans, initiating a
mare clausum policy in the Atlantic, declaring it close to other states. The king, who had been inquiring of Genoese experts about a seaway to India, commissioned the
Fra Mauro world map, which arrived in Lisbon in 1459. In 1456,
Diogo Gomes reached the
Cape Verde archipelago. In the next decade captains at the service of Prince Henry, discovered the remaining islands which were occupied during the 15th century. The Gulf of Guinea was reached in the 1460s.
After Prince Henry In 1460,
Pedro de Sintra reached Sierra Leone. Prince Henry died in November after which, given the meagre revenues, exploration was granted to Lisbon merchant
Fernão Gomes in 1469, who in exchange for the monopoly of trade in the Gulf of Guinea had to explore each year for five years. With his sponsorship, explorers
João de Santarém,
Pedro Escobar, Lopo Gonçalves,
Fernão do Pó, and Pedro de Sintra made it beyond those goals. They reached the Southern Hemisphere and islands of the Gulf of Guinea, including
São Tomé and Príncipe and
Elmina in 1471. There, in what came to be called the "Gold Coast", in today's
Ghana, a thriving alluvial gold trade was found among the natives, Arab and
Berber traders. In 1478, during the
War of the Castilian Succession, near the coast at
Elmina a
large battle was fought between a Castilian armada of 35 caravels, and a Portuguese fleet for the hegemony of the Guinea trade. The war ended with a Portuguese victory, followed by official recognition by the Catholic Monarchs of Portuguese sovereignty over most of the disputed West African territories embodied in the Treaty of Alcáçovas, 1479. In 1481,
João II decided to build
São Jorge da Mina factory. In 1482, the
Congo River was explored by
Diogo Cão, who in 1486 continued to
Cape Cross (modern
Namibia). The next crucial breakthrough was in 1488, when
Bartolomeu Dias rounded the southern tip of Africa, which he named Cabo das Tormentas, "Cape of Storms", then sailing east as far as the mouth of the
Great Fish River, proving the Indian Ocean was accessible from the Atlantic.
Pero da Covilhã, sent out travelling secretly overland, had reached
Ethiopia having collected important information about the Red Sea and Quenia coast, suggesting a sea route to the Indies would soon be forthcoming. Soon the cape was renamed by King
John II of Portugal the
Cape of Good Hope, because of the optimism engendered by the possibility of a sea route to India, proving false the view that had existed since
Ptolemy that the Indian Ocean was
land-locked. Based on later stories of the
phantom island known as
Bacalao and the carvings on
Dighton Rock some have speculated that Portuguese explorer
João Vaz Corte-Real discovered
Newfoundland in 1473, but the sources are considered unreliable.
Spanish exploration: Columbus's landfall in the Americas , 1492–1503 Portugal's Iberian rival,
Castile, had begun to establish its rule over the Canary Islands in 1402, but became distracted by internal Iberian politics and the repelling of Islamic invasion attempts through most of the 15th century. Following the unification of the crowns of Castile and Aragon, an emerging modern Spain became committed to the search for new trade routes overseas. The
Crown of Aragon had been an important maritime power, controlling territories in eastern Spain, southwestern France, major islands like
Sicily,
Malta, and the
Kingdom of Naples and
Sardinia, with mainland possessions as far as Greece. In 1492 the
joint rulers conquered the
Moorish kingdom of Granada, which had been providing Castile with African goods through tribute, and decided to fund
Christopher Columbus's expedition in the hope of bypassing Portugal's monopoly on West African sea routes, to reach "the Indies" (East and South Asia) by travelling west. In 1485 and 1488, Columbus had presented the project to king
John II of Portugal, who rejected it. On 3 August 1492, Columbus departed from
Palos de la Frontera. Land was sighted on 12 October, and Columbus called the island
San Salvador (
Guanahani now in
The Bahamas), in what he thought to be the
East Indies. Columbus explored the north coast of
Cuba and
Hispaniola, by 5 December. He was received by the native
cacique Guacanagari, who gave him permission to leave some men behind.
, Pinta, and Santa María'' at
Palos de la Frontera, Spain Columbus left 39 and founded the settlement of
La Navidad in what is now
Haiti. Before returning to Spain, he kidnapped 10-25 natives. Only 7-8 of the 'Indians' arrived alive, but they made an impression on
Seville. On 15 March 1493, he arrived in
Barcelona, where he reported to Isabella and Ferdinand. Word of his discovery of new lands
spread throughout Europe. Columbus and other Spanish explorers were initially disappointed with their discoveries—unlike Africa or Asia, the Caribbean islanders had little to trade. The islands thus became the focus of colonization efforts. It was not until the continent was explored that Spain found the wealth it had sought.
Treaty of Tordesillas (1494) meridian (purple) and the later
Spice Islands antimeridian (green), set at the
Treaty of Zaragoza (1529) Shortly after Columbus's return from what would be called the "West Indies", a division of influence became necessary to avoid conflict between the Spaniards and Portuguese. On 4 May 1493, two months after Columbus's arrival, the
Catholic Monarchs received a
bull (
Inter caetera) from
Pope Alexander VI stating all lands west and south of a pole-to-pole line 100 leagues west and south of the
Azores or the Cape Verde Islands should belong to Castile and, later, all mainlands and islands then belonging to India. It did not mention Portugal, which could not claim newly discovered lands east of the line. King
John II of Portugal was displeased with the arrangement, feeling it gave him too little land—preventing him from reaching India, his goal. He negotiated directly with Ferdinand and Isabella to move the line west, allowing him to claim newly discovered lands east of it. In 1494, the
Treaty of Tordesillas divided the world between Portugal and Spain. Portugal gained control over Africa, Asia, and eastern South America (Brazil), encompassing everything outside Europe east of a line drawn 370
leagues west of the
Cape Verde islands. The Spaniards received everything west of this line, including the islands discovered by Columbus on
his first voyage. The dividing line, situated about halfway between Portuguese Cape Verde and Spanish discoveries in the Caribbean, split the known world of Atlantic islands evenly. In 1500,
Pedro Álvares Cabral, initially considering the Brazilian coast as a large island, claimed it for Portugal east of the dividing line. This claim was acknowledged by the Spaniards. Cabral, heading towards India, followed a corridor in the Atlantic negotiated by the treaty for favorable winds. Later the Spanish territory would prove to include huge areas of the continental mainland of North and South America, though Portuguese-controlled Brazil would expand across the line, and settlements by other European powers ignored the treaty.
The Americas: The New World showing the name "America" for the first time. Little of the divided area had actually been seen by Europeans, as it was only divided by a geographical definition rather than control on the ground. The desire to compete with the Ottoman Empire and Columbus's first voyage spurred further maritime exploration and, from 1497, other explorers headed west.
North America That year
John Cabot (), also a commissioned Italian, got
letters patent from King
Henry VII of England. Sailing from
Bristol Cabot crossed the Atlantic from a northerly latitude hoping the voyage to the "West Indies" would be shorter and made landfall in North America, possibly
Newfoundland. Prior to Cabot's voyage, the furthest European expeditions in the North Atlantic had been by Norse explorers, who established settlements in
Newfoundland and
Greenland, which were abandoned in the 11th century and mid-15th century, respectively. Merchants from Bristol had sponsored exploratory voyages in the 1480s, which did not report anything of note. In 1499,
João Fernandes Lavrador was licensed by the King of Portugal and together with
Pero de Barcelos they first sighted
Labrador, which was granted and named after him. Between 1499 and 1502, the brothers
Gaspar and
Miguel Corte Real explored and named the coasts of
Greenland and Newfoundland. Both explorations are noted in the 1502
Cantino planisphere.
The "True Indies" and Brazil In 1497, newly crowned King
Manuel I of Portugal sent an exploratory fleet eastwards, fulfilling his predecessor's project of finding a route to the Indies. In July 1499, news spread that the Portuguese had reached the "true Indies", as a letter was dispatched by the Portuguese king to the Spanish Monarchs. The third expedition by Columbus in 1498 was the beginning of the first successful Spanish colonization in the
West Indies, on the island of
Hispaniola. Despite growing doubts, Columbus refused to accept he had not reached the Indies. He discovered the mouth of the
Orinoco River on the north coast of South America and thought the huge quantity of fresh water coming from it could only be from a continental land mass, which he was certain was Asia. As shipping between
Seville and the West Indies grew, knowledge of the Caribbean islands, Central America and the northern coast of South America increased. One of these Spanish fleets, that of
Alonso de Ojeda and Amerigo Vespucci in 1499–1500 reached land at the coast of what is now
Guyana, where the two seem to have separated in opposite directions. Vespucci sailed southward, discovering the mouth of the
Amazon River in July 1499, and reaching 6°S, in present-day north east Brazil, before turning around.
Vicente Yáñez Pinzon was blown off course and reached what is now the northeast coast of Brazil on 26 January 1500, exploring as far south as the present-day state of
Pernambuco. His fleet was the first to fully enter the Amazon River estuary, which he named ''Saint Mary's River of the Freshwater Sea''. The land was too far east for the Castilians to claim under the Treaty of Tordesillas, but the discovery created Castilian interest, with a second voyage by Pinzon in 1508 (the
Pinzón–Solís voyage) and a voyage in 1515–1516 by a navigator of the 1508 expedition,
Juan Díaz de Solís. The 1515–1516 expedition was spurred on by reports of Portuguese exploration of the region. It ended when de Solís and some of his crew disappeared when exploring the
River Plata in a boat, but what they found reignited Spanish interest, and colonization began in 1531. In April 1500, the
second Portuguese India Armada, headed by
Pedro Álvares Cabral, with a crew of expert captains, encountered the Brazilian coast as it swung westward in the Atlantic while performing a large
volta do mar to avoid becalming in the
Gulf of Guinea. On 21 April, a mountain was seen and named
Monte Pascoal, and on 22 April Cabral landed. On 25 April, the entire fleet sailed into the harbour they named
Porto Seguro. Cabral perceived that the new land lay east of the line of Tordesillas, and sent an envoy to Portugal with the discovery in letters, including the
letter of
Pero Vaz de Caminha. Believing the land to be an island, he named it
Ilha de Vera Cruz. Some historians have suggested the Portuguese may have encountered the South American bulge earlier while sailing the "volta do mar", hence the insistence of John II in moving the line west of Tordesillas in 1494—so his landing in Brazil may not have been accidental; although John's motivation may have simply been to claim new lands in the Atlantic more easily. From the east coast, the fleet then turned eastward towards the southern tip of Africa and India. Cabral was the first captain to touch four continents, leading the first expedition that connected and united Europe, Africa, the New World, and Asia. At the invitation of King Manuel I of Portugal, Amerigo Vespucci participated as an observer in the exploratory voyages to the east coast of South America. The expeditions became widely known in Europe after two accounts attributed to him, published between 1502 and 1504, suggested the newly discovered lands were not the Indies but a "New World", the
Mundus novus; this is also the Latin title of a contemporary document based on Vespucci letters to
Lorenzo di Pierfrancesco de' Medici, which had become popular in Europe. It was understood that Columbus had not reached Asia but found a new continent, the Americas. The Americas were named in 1507 by
cartographers Martin Waldseemüller and
Matthias Ringmann, after Amerigo Vespucci. From 1501 to 1502, one of these Portuguese expeditions, led by
Gonçalo Coelho, sailed south along the coast of South America to the bay of present-day
Rio de Janeiro. Vespucci's account states that the expedition reached the latitude "South Pole elevation 52° S", in the "cold" latitudes of what is now southern
Patagonia, before turning back. Vespucci wrote that they headed toward the southwest and south, following "a long, unbending coastline", apparently coincident with the southern South American coast. This seems controversial, since he changed part of his description in the subsequent letter, stating a shift, from about 32° S (Southern Brazil) to the south-southeast, to open sea, maintaining that they reached 50°/52° S. In 1503,
Binot Paulmier de Gonneville, challenging the Portuguese policy of
mare clausum, led one of the earliest
French Normand and
Breton expeditions to Brazil. He intended to sail to the East Indies, but near the Cape of Good Hope, his ship was diverted to the west by a storm, and landed in the present-day state of
Santa Catarina (southern Brazil), on 5 January 1504. '' by

British Library, London. From 1511 to 1512, Portuguese captains
João de Lisboa and Estevão de Fróis reached the
River Plata estuary in present-day
Uruguay and
Argentina, and went as far south as the present-day
Gulf of San Matias at 42°S. The expedition reached a cape extending north to south which they called Cape of "Santa Maria" (
Punta del Este); and after 40°S they found a "Cape" or "a point or place extending into the sea", and a "Gulf". After they had navigated for nearly to round the cape, they again sighted the continent on the other side and steered towards the northwest, but a storm prevented them from making headway. Driven away by the
Tramontane or north wind, they retraced their course.
Christopher de Haro, a
Fleming of
Sephardic origin, who would serve the Spanish Crown after 1516, believed the navigators had discovered a southern
strait to west and Asia. In 1519, an expedition sent by the Spanish Crown to find a way to Asia was led by the experienced Portuguese navigator
Ferdinand Magellan. The fleet explored the rivers and bays as it charted the South American coast, until it found a way to the Pacific Ocean through the
Strait of Magellan. From 1524 to 1525,
Aleixo Garcia, a Portuguese conquistador, led a private expedition of shipwrecked Castilian and Portuguese adventurers, who recruited about 2,000
Guaraní Indians. They explored the territories of present-day southern Brazil,
Paraguay, and
Bolivia, using the native trail network, the
Peabiru. They were the first Europeans to cross the
Chaco and reach the outer territories of the
Inca Empire on the hills of the
Andes. ==Indian Ocean (1497–1513)==
