Portuguese Colonization

Portuguese maritime exploration resulted in the numerous territories and maritime routes recorded by the Portuguese as a result of their intensive maritime journeys during the 15th and 16th centuries. Portuguese sailors were at the vanguard of European exploration, chronicling and mapping the coasts of Africa and Asia, then known as the East Indies, and Canada and Brazil (the West Indies), in what came to be known as the Age of Discovery.

Methodical expeditions started in 1419 along West Africa's coast under the sponsorship of prince Henry the Navigator, with Bartolomeu Dias reaching the Cape of Good Hope and entering the Indian Ocean in 1488. Ten years later, in 1498, Vasco da Gama led the first fleet around Africa to India, arriving in Calicut and starting a maritime route from Portugal to India. Portuguese explorations then proceeded to southeast Asia, where they reached Japan in 1542, forty-four years after their first arrival in India. In 1500, the Portuguese nobleman Pedro Álvares Cabral became the first European to discover Brazil.

History

Origins

In 1139 the Kingdom of Portugal achieved independence from León and under the leadership of Afonso Henriques doubled its area with the Reconquista.

In 1297, King Dinis of Portugal took personal interest in the development of exports and organized the export of surplus production to European countries. On May 10, 1293, he instituted a maritime insurance fund for Portuguese traders living in the County of Flanders, which were to pay certain sums according to tonnage, accrued to them when necessary. Wine and dried fruits from Algarve were sold in Flanders and England, salt from Setúbal and Aveiro was a profitable export to northern Europe, and leather and kermes, a scarlet dye, were also exported. Portugal imported armor and munitions, fine clothes, and several manufactured products from Flanders and Italy.

In 1317, King Dinis made an agreement with Genoese merchant sailor Manuel Pessanha (Pessagno), appointing him first Admiral with trade privileges with his homeland in return for twenty warships and crews, with the goal of defending the country against Muslim pirate raids, thus laying the basis for the Portuguese Navy and establishment of a Genoese merchant community in Portugal. Forced to reduce their activities in the Black Sea, the Republic of Genoa had turned to North Africa for trade in wheat and olive oil and a search for gold – navigating also into the ports of Bruges (Flanders) and England. Genoese and Florentine communities were established in Portugal, which profited from the enterprise and financial experience of these rivals of the Republic of Venice.

In the second half of the fourteenth century outbreaks of bubonic plague led to severe depopulation: the economy was extremely localized in a few towns, and migration from the country led to the abandonment agricultural land and an increase in rural unemployment. Only the sea offered opportunities, with most people settling in fishing and trading areas along the coast. Between 1325 and 1357 Afonso IV of Portugal granted public funding to raise a proper commercial fleet and ordered the first maritime explorations, with the help of Genoese, under command of admiral Manuel Pessanha. In 1341 the Canary Islands, already known to Genoese seafarers, were officially discovered under the patronage of the Portuguese king, but in 1344 Castile disputed ownership of them, further propelling the Portuguese naval efforts.

Atlantic exploration (1418–1488)

In 1415, the Portuguese occupied the North African city of Ceuta to gain a foothold on Morocco and control shipping through the Strait of Gibraltar. They also hoped to extend Christianity and provide an outlet for Portuguese nobles looking to gain riches and honor in war. Among the participants of the action was the young Prince Henry the Navigator. Appointed governor of the Order of Christ in 1420, while personally holding profitable monopolies on resources in Algarve, he took the lead role in encouraging Portuguese maritime exploration until his death in 1460. He invested in sponsoring voyages down the coast of Mauritania, gathering a group of merchants, shipowners, and other stakeholders interested in new opportunities for maritime trade. Later his brother Prince Pedro granted him a royal monopoly of all profits from trading within the areas discovered.

In 1418, two of Henry's captains, João Gonçalves Zarco and Tristão Vaz Teixeira were driven by a storm to Porto Santo an uninhabited island off the coast of Africa which may have been known to Europeans since the 14th century. In 1419 Zarco and Teixeira made a landfall on Madeira. They returned with Bartolomeu Perestrelo and Portuguese settlement of the islands began. There, wheat and later sugarcane were cultivated, as in Algarve, by the Genoese, becoming profitable activities. This helped both them and Prince Henry become wealthier.

A Portuguese attempt to capture Grand Canary, one of the nearby Canary Islands, which had been partially settled by Spaniards in 1402 was unsuccessful and met with protestations from Castile. Although the exact details are uncertain, cartographic evidence suggests the Azores were probably discovered in 1427 by Portuguese ships sailing under Henry's direction, and settled in 1432, suggesting that the Portuguese were able to navigate at least from the Portuguese coast.

At around the same time as the unsuccessful attack on the Canary Islands, the Portuguese began to explore the North African coast. Sailors feared what lay beyond Cape Bojador at the time, as Europeans did not know what lay beyond on the African coast, and did not know whether it was possible to return once it was passed. Henry wished to know how far the Muslim territories in Africa extended, and whether it was possible to reach the source of the lucrative tran-Saharan caravan gold trade and perhaps to join forces with the long-lost Christian kingdom of Prester John that was rumoured to exist somewhere to the east.Rafiuddin Shirazi, Tazkiratul Mulk.

In 1434, one of Prince Henry's captains, Gil Eanes, passed this obstacle. Once this psychological barrier had been crossed, it became easier to probe further along the coast. Within two decades of exploration, Portuguese ships had bypassed the Sahara. Westward exploration continued over the same period: Diogo de Silves discovered the Azores island of Santa Maria Island, Santa Maria in 1427 and in the following years Portuguese mariners discovered and settled the rest of the Azores.

Henry suffered a serious setback in 1437 after Battle of Tangier (1437), the failure of an expedition to capture Tangier, having encouraged his brother, King Edward of Portugal, Edward, to mount an overland attack from Ceuta. The Portuguese army was defeated and only escaped destruction by surrendering Ferdinand the Holy Prince, Prince Ferdinand, the king's youngest brother. After the defeat at Tangier, Henry retired to Sagres (Vila do Bispo), Sagres on the southern tip of Portugal where he continued to direct Portuguese exploration until his death in 1460.

In 1443, Prince Pedro, Duke of Coimbra, Prince Pedro, Henry's brother, granted him the monopoly of navigation, war, and trade in the lands south of Cape Bojador. Later this monopoly would be backed by the Papal bulls ''Dum Diversas'' (1452) and ''Romanus Pontifex'' (1455), granting Portugal a trade monopoly for the newly discovered countries.

The caravel, an existing ship type, was used in exploration from about 1440. It had a number of advantageous characteristics. These included shallow draft, which was suitable for approaching unknown coasts, and an efficient combination of hull shape (including a rudder attached to the sternpost, unlike some other contemporary types with side-mounted steering oars) and lateen rig, which gave a fast-sailing vessel which had better Windward and leeward, windward sailing ability than other vessels of the time.

Portuguese navigators reached ever more southerly latitudes, advancing at an average rate of one degree a year. Senegal and Cape Verde Peninsula were reached in 1445. In the same year, the first overseas ''feitoria'' (trading post) was established under Henry's direction, on the island of Arguin off the coast of Mauritania. It was created to attract Muslim traders and monopolize the business in the routes traveled in North Africa, starting the chain of Portuguese ''feitorias'' along the coast. In 1446, Álvaro Fernandes pushed on almost as far as present-day Sierra Leone, and the Gulf of Guinea was reached in the 1460s.

Exploration after Prince Henry

As a result of the first meager returns of the African explorations, in 1469 king Afonso V of Portugal, Afonso V granted the monopoly of trade in part of the Gulf of Guinea to merchant Fernão Gomes, for an annual payment of 200,000 Portuguese real, reals. Gomes was also required to explore of the coast each year for five years. He employed explorers João de Santarém, Pedro Escobar, Lopes Gonçalves, Lopo Gonçalves, Fernão do Pó, and Pedro de Sintra, and exceeded the requirement. Under his sponsorship, Portuguese explorers crossed the equator into the Southern Hemisphere and found the islands in the Gulf of Guinea, including São Tomé and Príncipe.

In 1471, Gomes' explorers reached Elmina on the Gold Coast (present day Ghana), and discovered a thriving overland gold trade between the natives and visiting Arab and Berber traders. Gomes established his own trading post there, which became known as “A Mina” ("The Mine"). Trade between Elmina and Portugal grew in the next decade. In 1481, the recently crowned John II of Portugal, João II decided to build São Jorge da Mina fort (Elmina Castle) and factory to protect this trade, which was then held again as a royal monopoly.

In 1482, Diogo Cão discovered the mouth of the Congo River. In 1486, Cão continued to Cape Cross, in present-day Namibia, near the Tropic of Capricorn.

In 1488, Bartolomeu Dias rounded the Cape of Good Hope near the southern tip of Africa, disproving the view that had existed since Ptolemy that the Indian Ocean was separate from the Atlantic. Also at this time, Pêro da Covilhã reached India via Egypt and Yemen, and visited Madagascar. He recommended further exploration of the southern route.

As the Portuguese explored the coastlines of Africa, they left behind a series of Padrão, padrões, stone crosses inscribed with the Portuguese coat of arms marking their claims, and built forts and trading posts. From these bases, the Portuguese engaged profitably in the slave and gold trades. Portugal enjoyed a virtual monopoly of the Atlantic slave trade for over a century, exporting around 800 slaves annually. Most were brought to the Portuguese capital Lisbon, where it is estimated black Africans came to constitute 10 percent of the population.

Tordesillas division of the world (1492)

In 1492 Christopher Columbus's discovery for Spain of the New World, which he believed to be Asia, led to disputes between the Spanish and Portuguese. These were eventually settled by the Treaty of Tordesillas in 1494 which divided the world outside of Europe in an exclusive duopoly between the Portuguese and the Spanish, along a north–south Meridian (geography), meridian 370 League (unit), leagues, or , west of the Cape Verde islands. However, as it was not possible at the time to correctly measure longitude, the exact boundary was disputed by the two countries until 1777.

The completion of these negotiations with Spain is one of several reasons proposed by historians for why it took nine years for the Portuguese to follow up on Dias's voyage to the Cape of Good Hope, though it has also been speculated that other voyages were, in fact, taking place in secret during this time. Whether or not this was the case, the long-standing Portuguese goal of finding a sea route to Asia was finally achieved in a ground-breaking voyage commanded by Vasco da Gama.

Reaching India and Brazil (1497–1500)

Vasco da Gama's squadron left Portugal on 8 July 1497, consisting of four ships and a crew of 170 men. It rounded the Cape and continued along the coast of Southeast Africa, where a local pilot was brought on board who guided them across the Indian Ocean, reaching Calicut in western India in May 1498. After some conflict, da Gama got an ambiguous letter for trade with the Zamorin of Calicut, leaving there some men to establish a trading post.

Vasco da Gama's voyage to Calicut was the starting point for deployment of Portuguese ''feitoria'' posts along the east coast of Africa and in the Indian Ocean. Shortly after, the Casa da Índia was established in Lisbon to administer the royal monopoly of navigation and trade. Exploration soon lost private support, and took place under the exclusive patronage of the Portuguese Crown.

The second voyage to India was dispatched in 1500 under Pedro Álvares Cabral. While following the same south-westerly route across the Atlantic Ocean as da Gama (to take advantage of the most favorable winds), Cabral made landfall on the Brazilian coast. This was probably an accidental discovery, but it has been speculated that the Portuguese secretly knew of Brazil's existence and that it lay on their side of the Tordesillas line. Cabral recommended to the Portuguese King that the land be settled, and two follow-up voyages were sent in 1501 and 1503. The land was found to be abundant in ''pau-brasil'', or brazilwood, from which it later inherited its name, but the failure to find gold or silver meant that for the time being Portuguese efforts were concentrated on India.

Indian Ocean explorations (1497–1542)

The aim of Portugal in the Indian Ocean was to ensure the monopoly of the spice trade. Taking advantage of the rivalries that pitted Hindus against Muslims, the Portuguese established several forts and trading posts between 1500 and 1510. In East Africa, small Islamic states along the coast of Mozambique, Kilwa Kisiwani, Kilwa, Barawa, Brava, Sofala and Mombasa were destroyed, or became either subjects or allies of Portugal. Pêro da Covilhã had reached Ethiopia (via the Indian Ocean coast in Somalia, traveling secretly overland, as early as 1490; a diplomatic mission reached the ruler of that nation on October 19, 1520.

In 1500, the second fleet to India (which also made landfall in Brazil) explored the East African coast in Southeast Africa, where Diogo Dias discovered the island that he named St. Lawrence, later known as Madagascar. This fleet, commanded by Pedro Álvares Cabral, arrived at Calicut in September, where the first trade agreement in India was signed. For a short time a Portuguese factory was installed there, but it was attacked by Muslims on December 16 and several Portuguese, including the scribe Pêro Vaz de Caminha, died. After bombarding Calicut as a retaliation, Cabral went to rival Kochi, India, Kochi.

Profiting from the rivalry between the Maharaja of Kochi and the Zamorin of Calicut, the Portuguese were well received and seen as allies, getting a permit to build a Fort Kochi, fort (Fort Manuel) and a trading post that was the first European settlement in India. There in 1503 they built the St. Francis Church, Kochi, St. Francis Church. In 1502 Vasco da Gama took the island of Kilwa on the coast of Tanzania, where in 1505 the first fort of Portuguese East Africa was built to protect ships sailing in the East Indian trade.

In 1505, king Manuel I of Portugal appointed Francisco de Almeida first Viceroy of Portuguese India for a three-year period, starting the Portuguese government in the east, headquartered at Kochi. That year the Portuguese conquered Kannur where they founded St. Angelo Fort. The Viceroy's son Lourenço de Almeida arrived in Ceylon (modern Sri Lanka), where he discovered the source of cinnamon. Finding it divided into seven rival kingdoms, he established a defense pact with the kingdom of Kotte and extended the control in coastal areas, where in 1517 was founded the fortress of Colombo.

In 1506, a Portuguese fleet under the command of Tristão da Cunha and Afonso de Albuquerque, conquered Socotra at the entrance of the Red Sea and Muscat, Oman, Muscat in 1507, having failed to conquer Ormuz, following a strategy intended to close those entrances into the Indian Ocean. That same year, fortresses were built in the Island of Mozambique and Mombasa on the Kenyan coast. Madagascar was partly explored by Tristão da Cunha and in the same year Mauritius was discovered.

In 1509, the Portuguese won the sea Battle of Diu (1509), Battle of Diu against the combined forces of the Ottoman Empire, Ottoman Sultan Beyazid II, the Gujarat Sultanate, Sultan of Gujarat, the Mamluk, Mamlûk Sultan of Cairo, the Samoothiri Raja of Kozhikode, the Venetian Republic, and the Ragusan Republic (Dubrovnik). The Portuguese victory was critical for its strategy of control of the Indian Ocean: the Turks and Egyptians withdrew their navies from India, leaving the seas to the Portuguese, setting its trade dominance for almost a century, and greatly assisting the growth of the Portuguese Empire. It also marked the beginning of European colonial dominance in Asia. A second Siege of Diu, Battle of Diu in 1538 finally ended Ottoman ambitions in India, and confirmed Portuguese hegemony in the Indian Ocean.

Under the government of Albuquerque, Goa was taken from the Adil Shahi dynasty, Bijapur sultanate in 1510 with the help of Hindu privateer Timoji. Coveted for being the best port in the region, mainly for the commerce in Arabian horses for the Deccan sultanates, it allowed the Portuguese to move on from their initial guest stay in Cochin. Despite constant attacks, Goa became the seat of the Portuguese government, under the name of Portuguese India, ''Estado da India'' (State of India), with the conquest triggering compliance of neighbor kingdoms: Gujarat and Calicut sent embassies, offering alliances and grants to fortify. Albuquerque began that year in Goa the first Portuguese Mint (coin), mint in India, taking the opportunity to announce the achievement.

Southeast Asia expeditions

In April 1511 Albuquerque sailed to Malacca in modern-day Malaysia, the most important eastern point in the trade network, where Malay met Gujarati, Chinese, Japanese, Javanese, Bengali, Persian and Arabic traders, described by Tomé Pires as invaluable. The port of Malacca became then the strategic base for Portuguese trade expansion with China and Southeast Asia, under the Portuguese rule in India with its capital at Goa. To defend the city a strong fort was erected, called the "A Famosa", where one of its gates still remains today. Learning of Siamese ambitions over Malacca, Albuquerque immediately sent Duarte Fernandes on a diplomatic mission to the Ayutthaya Kingdom, kingdom of Siam (modern Thailand), where he was the first European to arrive, establishing amicable relations between the two kingdoms. In November that year, getting to know the location of the so-called "Maluku Islands, Spice Islands" in the Moluccas, Albuquerque sent an expedition to find them. Led by António de Abreu, the expedition arrived in early 1512. Abreu went by Ambon, while his deputy commander Francisco Serrão advanced to Ternate, where a Portuguese fort was allowed. That same year, in Indonesia, the Portuguese took Makassar, reaching Timor in 1514. Departing from Malacca, Jorge Álvares came to southern China in 1513. This visit followed the arrival in Guangzhou, where trade was established. Later a trading post at Macau would be established.

The Portuguese empire expanded into the Persian Gulf as Portugal contested control of the spice trade with the Ottoman Empire. In 1515, Afonso de Albuquerque conquered the Huwala state of Ormus, Hormuz at the head of the Persian Gulf, establishing it as a vassal state. Aden, however, resisted Albuquerque's expedition in that same year, and another attempt by Albuquerque's successor Lopo Soares de Albergaria in 1516. Bahrain was captured in 1521, when a force led by António Correia (admiral), António Correia defeated the Jabrid King, Muqrin ibn Zamil. In a shifting series of alliances, the Portuguese dominated much of the southern Persian Gulf for the next hundred years. The island of Mozambique became a strategic port on the regular maritime route linking Lisbon to Goa, and Fort São Sebastião and a hospital were built there. In the Azores, the Armada of the Islands protected ships from the Indies en route to Lisbon.

In 1525, after Fernão de Magalhães's expedition (1519–1522), Spain under Charles V sent an expedition to colonize the Moluccas islands, claiming that they were in his zone of the Treaty of Tordesillas, since there was not a set limit to the east. Led by Loaísa expedition, García Jofre de Loaísa, the expedition reached the Moluccas, docking at Tidore. Conflict with the Portuguese already established in nearby Ternate was inevitable, starting nearly a decade of skirmishes. An agreement was reached only with the Treaty of Zaragoza (1529), which gave the Moluccas to Portugal and the Philippines to Spain.

In 1530, John III of Portugal, John III organized the colonization of Colonial Brazil, Brazil around 15 ''capitanias hereditárias'' ("hereditary captainships"), that were given to anyone who wanted to administer and explore them, to overcome the need to defend the territory, since an expedition under the command of Gonçalo Coelho in 1503 had found the French making incursions on the land. That same year, there was a new expedition from Martim Afonso de Sousa with orders to patrol the whole Brazilian coast, banish the French, and create the first colonial towns: São Vicente, Brazil, São Vicente on the coast, and São Paulo (city), São Paulo near the edge of the inland plateau (''planalto'') and the Serra do Mar. From the 15 original captainships, only two, Pernambuco and São Vicente, prospered. With permanent settlement came the establishment of the sugar cane industry and its intensive labor demands which were met with Indigenous peoples of the Americas, Native American and later African slaves.

In 1534, Gujarat was occupied by the Mughals and the Sultan Bahadur Shah of Gujarat was forced to sign the Treaty of Bassein (1534) with the Portuguese, establishing an alliance to regain the country, giving in exchange Daman, Daman and Diu, Daman, Diu, India, Diu, Mumbai, and Vasai, Bassein. In 1538 the fortress of Diu was again surrounded by Ottoman ships. Another siege failed in 1547, putting an end to Ottoman ambitions and confirming Portuguese hegemony.

In 1542 Jesuit missionary Francis Xavier arrived in Goa at the service of King John III of Portugal, in charge of an Apostolic Nunciature. At the same time Francisco Zeimoto, António Mota, and other traders arrived in Japan for the first time. According to Fernão Mendes Pinto, who claimed to be in this journey, they arrived at Tanegashima, where the locals were impressed by European Firearms of Japan, firearms, which would be immediately made by the Japanese on a large scale. In 1557 the Chinese authorities allowed the Portuguese to settle in Macau through an annual payment, creating a warehouse in the triangular trade between China, Japan and Europe. In 1570 the Portuguese bought a Japanese port where they founded the city of Nagasaki, thus creating a trading center that for many years was the port from Japan to the world.

Portugal established trading ports at far-flung locations like Goa, Ormuz, Portuguese Malacca, Malacca, Kochi, India, Kochi, the Maluku Islands, Colonial Macau, Macau, and Nagasaki, Nagasaki, Nagasaki. Guarding its trade from both European and Asian competitors, Portugal dominated not only the trade between Asia and Europe, but also much of the trade between different regions of Asia, such as India, Indonesia, China, and Japan. Society of Jesus, Jesuit missionaries, such as the Francis Xavier, followed the Portuguese to spread Christianity to Asia with mixed success.

Besides Magellan, also participated in the trip Diogo and Duarte Barbosa, João Serrão, Álvaro de Mesquita (Magellan's nephew), the pilots João Rodrigues de Carvalho and Estêvão Gomes, Enrique of Malacca, Henrique of Malacca, among others. Many of them cross almost all longitudes or all longitudes reaching the Philippines, Borneo and the Moluccas, because they had previously visited India, Mallacca, the Indonesian Archipelago or the Moluccas (1511-1512), like Ferdinand Magellan in the 7th Portuguese India Armada (Almeida, 1505), 7th Portuguese India Armada under the command of Francisco de Almeida and on the expeditions of Diogo Lopes de Sequeira, Afonso de Albuquerque and his other voyages, sailing eastward from Lisbon (as Magellan in 1505), and then later, in 1521, sailing westward from Seville, reaching that longitude and region once again and then proceeding still further west.
*1525—Aleixo Garcia explored the Rio de la Plata in service to Spain as a member of the expedition of Juan Díaz de Solís in 1516. Solís had left Portugal towards Castile (Spain) in 1506 and would be financed by Christopher de Haro, who had served Manuel I of Portugal until 1516. Serving Charles I of Spain after 1516, Haro believed that Lisboa and Frois had discovered a major route in the Southern New World to west or a ''strait'' to Asia two years earlier. Later (when returning and after a shipwreck on the coast of Brazil), from Santa Catarina, Brazil, and leading an expedition of some European and 2,000 Guaraní people, Guaraní Indians, Aleixo Garcia explored Paraguay and Bolivia using the trail network Peabiru. Aleixo Garcia was the first European to cross the Gran Chaco, Chaco and even managed to penetrate the outer defenses of the Inca Empire on the hills of the Andes (near Sucre), in present-day Bolivia.

*1525—Exploration of the Pacific, Diogo da Rocha and his pilot Gomes de Sequeira reached Sulawesi, Celebes and were blown off course and driven three hundred leagues in a direction constantly towards the east and to ''Ilhas de Gomes de Sequeira'' - most probably the Palau Island or Yap, (Caroline Islands) according to the geographical notes, distance traveled and physical description of the natives in ''Décadas da Ásia'' of João de Barros, or, according to the alleged existence of gold mentioned by the natives, other descriptions of the people and if they were to south and east in one or two voyages made by Gomes de Sequeira (According to the different interpretations of the Chronicles of Barros, Castanheda and Galvão), raises also the hypothesis of Cape York Peninsula in Australia, maybe one of the Prince of Wales Islands. In Gastald's map a group of islands named ''Insul de gomes des queria'' lie in about 8 degrees of south latitude and in the longitude of the Northern Territory of Australia. In the same map the ''Apem insul'' seems to correspond with either Adi Island or the Aru Islands. The (''Islands of the White Men'') correspond, as far as locality is concerned, to the Arru (Aru) Islands. It would appear then that Gomes de Sequeira's Islands, which are the south-easternmost of those represented, must correspond with the Timor Laut group. In the same year, according to the voyages to the ''Banda'' Islands mentioned on ''Decadas'' and according to contemporaneous cartographers, Martim Afonso de Melo (Jusarte) and Garcia Henriques explored the Tanimbar Islands (the archipelago labelled "''aqui invernou Martim Afonso de Melo''" and "''Aqui in bernon Martin Afonso de melo''" [Here wintered Martin Afonso de Melo]) and probably the Aru Islands (the two archipelagos and the navigator mentioned in the maps of Lázaro Luís, 1563, Bartolomeu Velho, c. 1560, Sebastião Lopes, c. 1565 and also in the 1594 map of the East Indies entitled ''Insulce Molucoe'' by the Dutch cartographer Petrus Plancius and in the map of ''Nova Guinea'' of 1600).
