The Portuguese Empire (Portuguese: Império Português) was the first global empire in history, with territories in South America, Africa, India and South East Asia that were reached during Portuguese overseas exploration of the Age of Discovery. It was also the longest lived of the modern European colonial empires, spanning almost six centuries, from the capture of Ceuta in 1415 to the handover of Macau in 1999.

Portuguese sailors began exploring the coast of Africa in 1419, making use of the latest developments in navigation, cartography and maritime technology such as the caravel, in order that they might find a sea route to the source of the lucrative spice trade. In 1488, Bartolomeu Dias rounded the Cape of Good Hope, and in 1498, Vasco da Gama reached India. In 1500, by an accidental landfall on the South American coast for some, by the crown's secret design for others, Pedro Álvares Cabral would find and lead to the establishment of the colony of Brazil. Over the following decades, Portuguese sailors continued to explore the coasts and islands of East Asia, establishing forts and factories as they went. By 1571, a string of outposts connected Lisbon to Nagasaki: the empire had become truly global, and in the process brought great wealth to Portugal.

Between 1580 and 1640 Portugal became the junior partner to Spain in the union of the two countries' crowns. Though the empires continued to be administered separately, Portuguese colonies became the subject of attacks by three rival European powers hostile to Spain and envious of Iberian successes overseas: The Netherlands (which was engaged in a war of independence against Spain), England and France. With a smaller population, Portugal was unable to effectively defend its overstretched network of trading posts, and so the empire began its long and gradual decline.

With the end of the Portuguese trade monopoly in the Indian Ocean, after significant losses in Portuguese India and Southeast Asia, it turned to Brazil. The independence of Brazil in 1822, by then Portugal's largest and most profitable colony, at a time when independence movements were sweeping the Americas, was a blow from which Portugal and its empire would never recover.

The Scramble for Africa which began in the late 19th century left Portugal with a handful of colonies on the continent. Most of these African territories were under Portuguese administration and influence for centuries. Cities like Luanda and Benguela, and dozens of other settlements, ports and forts, had been founded and ruled by Portugal since the 16th century. After World War II, Portugal's leader, António Salazar, attempted to keep the Portuguese Empire intact at a time when other European countries were beginning to withdraw from their colonies. In 1961 the handful of Portuguese troops garrisoned in Goa were unable to prevent Indian troops marching into the colony. Salazar began a long and bloody war to quell anti-colonialist forces in the African colonies. The unpopular war lasted until the overthrow of the regime in 1974, known as the Carnation Revolution. The new government immediately changed policy and recognised the independence of all its colonies, except for Macau, which by agreeement with the Chinese government was returned to China in 1999, marking the end of the Portuguese overseas empire.

The Community of Portuguese Language Countries (CPLP) is the cultural successor of the Empire.

Origins (1139–1415)

The origins of the Portuguese Empire, and of Portugal itself, lay in the reconquista—the gradual Christian reconquest of the Iberian peninsula from the Moors. After establishing itself as a separate kingdom in 1139, Portugal completed its reconquista by 1249, but its independence continued to be threatened by neighbouring Castile until the signing of the Treaty of Ayllón in 1411. Free from threats to its existence, Portuguese attention turned overseas and towards a military expedition to the Muslim lands of North Africa.Newitt, p. 19 There were several probable motives for an attack on the Marinid Sultanate in present-day Morocco. It offered the opportunity to continue the Christian crusade aspect of the reconquista against Islam. To the military class, it promised glory on the battlefield and the spoils of war.Boxer, p. 19 It was also a chance to expand Portuguese trade and to address Portugal's economic decline.
In 1415 an attack was made on Ceuta, a strategically located Muslim city at the mouth of the Mediterranean Sea, and one of the terminal ports of the trans-Saharan gold and slave trades. The Battle of Ceuta was a military success, and marked one of the first steps in Portuguese expansion beyond the Iberian Peninsula, but it proved costly to defend against the Muslim forces that soon besieged it. The Portuguese were unable to use it as a base for further expansion into the hinterland, and the trans-Saharan trade routes shifted to use alternative Muslim ports.Diffie, p. 55

Age of discovery (1415–1542)

thumb|right|150px|Prince Henry the Navigator, generally credited as the driving force behind Portuguese maritime exploration.
Although Ceuta proved to be a disappointment for the Portuguese, the decision was taken to hold it while exploring along the Atlantic African coast. A key supporter of this policy was Prince Henry the Navigator, who had been involved in the capture of Ceuta, and who took the lead role in encouraging Portuguese maritime exploration until his death in 1460. At the time, Europeans did not know what lay beyond Cape Bojador on the African coast. Henry wished to know how far the Muslim territories in Africa extended, and whether it was possible to reach Asia by sea, both to reach the source of the lucrative spice trade and perhaps to join forces with the long-lost Christian kingdom of Prester John that was rumoured to exist somewhere in the "Indies".
In 1419 two of Henry's captains, João Gonçalves Zarco and Tristão Vaz Teixeira were driven by a storm to Madeira, an uninhabited island off the coast of Africa which had probably been known to Europeans since the 14th century. In 1420 Zarco and Teixeira returned with Bartolomeu Perestrelo and began Portuguese settlement of the islands. 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.
thumb|left|200px|The caravel ship introduced in the mid-15th century which aided Portuguese exploration
At around the same time as the unsuccessful attack on the Canary Islands, the Portuguese began to explore the North African coast. Sailors' fears of what lay beyond Cape Bojador, and whether it was possible to return once it was passed. 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. Westward exploration continued over the same period: Diogo Silves discovered the Azores island of Santa Maria in 1427 and in the following years Portuguese discovered and settled the rest of the Azores. Within two decades of exploration, Portuguese ships bypassed the Sahara.

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

In 1443 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 enforced by the Papal bulls Dum Diversas (1452) and Romanus Pontifex (1455), granting Portugal the trade monopoly for the newly discovered countries, > laying the basis for the Portuguese empire.

A major advance which accelerated this project was the introduction of the caravel in the mid-15th century, a ship that could be sailed closer to the wind than any other in operation in Europe at the time. Using this new maritime technology, 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. The first feitoria trade post overseas was established then under Henry directions, in 1445 on the island of Arguin off the coast of Mauritania, 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, António Fernandes pushed on almost as far as present-day Sierra Leone and the Gulf of Guinea was reached in the 1460s.

As a result of the first meager returns of the African explorations, in 1469 king Afonso V granted the monopoly of trade in part of the Gulf of Guinea to merchant Fernão Gomes against an annual income of 200,000 reis. Gomes had to explore 100 miles of the coast each year for five years. In collaboration with explorers João de Santarém, Pedro Escobar, Lopo Gonçalves, Fernão do Pó, and Pedro de Sintra, he made it even beyond the hired. With his sponsorship, the Portuguese reached the Southern Hemisphere and found the islands of the Gulf of Guinea, including São Tomé and Príncipe and Elmina on the Gold Coast in 1471.

Upon reaching present day Elmina, Gomes discovered a thriving gold trade among the natives and visiting Arab and Berber traders. He established his own trading post, that became known as “A Mina” (the Mine). Trade between Elmina and Portugal grew throughout a decade. In 1481, the recently-crowned João II decided to build São Jorge da Mina fort (Elmina Castle) and factory in order to ensure the protection of this trade, which was then held again as a royal monopoly.

The Equator was crossed by navigators under Fernão Gomes exploration in 1473 and the Congo River by Diogo Cão in 1482. 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 on the southern tip of Africa, proving false the view that had existed since Ptolemy that the Indian Ocean was land-locked. Simultaneously Pêro da Covilhã, traveling secretly overland, had reached Ethiopia, suggesting that a sea route to the Indies would soon be forthcoming.

As the Portuguese explored the coastlines of Africa, they left behind a series of padrões, stone crosses enscribed 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 on the African seaborne slave trade for over a century, importing around 800 slaves annually. Most were brought to the Portuguese capital Lisbon, where it is estimated black Africans came to constitute 10 per cent of the population.

Division of the world (1492)

The 1494 Tordesilhas Treaty meridian dividing the world between Portugal and Castille/Spain (purple) and the Moluccas antimeridian (green), set at the Treaty of Zaragoza, 1529

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 370 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.

The squadron of Vasco da Gama left Portugal in 1497, rounded the Cape and continued along the coast of East Africa, where a local pilot was brought on board who guided them across the Indian Ocean, reaching Calicut in western India in May 1498. The second voyage to India was dispatched in 1500 under Pedro Álvares Cabral. While following the same south-westerly route as da Gama across the Atlantic Ocean, 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 travel led by Vasco da Gama to Calicut was the starting point for deployment of Portuguese in the African east coast and in the Indian Ocean. The first contact occurred on 20 May 1498. After some conflict, he got an ambiguous letter for trade with the Zamorin of Calicut, leaving there some men to establish a trading post. Since then explorations lost the private nature, taking place under the exclusive of the Portuguese Crown. Shortly after, was established in Lisbon the Casa da India to administer the royal monopoly of navigation and trade.

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 and 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, Brava, Sofala and Mombasa were destroyed, or became either subjects or allies of Portugal. Pêro da Covilhã had reached Ethiopia, 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 who came to discover Brazil explored the East African coast, where Diogo Dias discovered the island that he named St. Lawrence, later known as Madagascar. This fleet, commanded by Pedro Alvares Cabral, arrived at Calicut in September, where was signed the first trade agreement in India. For a short time a Portuguese factory was installed there, but was attacked by Muslims on December 16, having died several Portuguese, including the scribe Pero Vaz de Caminha. After bombarding Calicut, Cabral went to rival 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 (Fort Manuel) and a trading post that were the first European settlement in India. There in 1503 they built the St. Francis ChurchAyub, Akber (ed), Kerala: Maps & More, Fort Kochi, 2006 edition 2007 reprint, pp. 20-24, Stark World Publishing, Bangalore, ISBN 81-902505-2-3. In 1502 Vasco da Gama took the island of Kilwa on the coast of Tanzania, where in 1505 was built the first fort of Portuguese East Africa to protect ships from 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. 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 in 1507, having failed to conquer Ormuz, following a strategy intended to close the entrances to the Indian Ocean. That same year were built fortresses 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 against the combined forces of the Ottoman Sultan Beyazid II, Sultan of Gujarat, Mamlûk Sultan of Cairo, Samoothiri Raja of Kozhikode, Venetian Republic, and Ragusan Republic (Dubrovnik). The Portuguese victory was critical for its strategy of control of the Indian Sea: Turks and Egyptians withdraw 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 marked also the beginning of the European colonial dominance in the Asia. A second 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 Bijapur sultanate in 1510 with the help of Hindu privateer Timoji. Coveted for being the best port in the region, mainly for the commerce of Arabian horses for the Deccan sultanates, it allowed to move on from the initial guest stay in Cochin. Despite constant attacks, Goa became the seat of the Portuguese government, under the name of Portuguese India, with the conquest triggering compliance of neighbour kingdoms: Gujarat and Calicut sent embassies, offering alliances and grants to fortify. Albuquerque began that year in Goa the first Portuguese mint in India, taking the opportunity to announce the achievement.

Initially king Manuel I and his council tried to distribute power from Lisbon, creating three areas of jurisdiction in the Indian Ocean: Albuquerque followed to the Red Sea, Diogo Lopes de Sequeira was sent to Southeast Asia, seeking an agreement with the Sultan of Malacca, Jorge de Aguiar and Duarte de Lemos were sent to the area between the Cape of Good Hope and Gujarat. However, such posts were centralised by Afonso de Albuquerque, and remained so.

In April 1511 Albuquerque sailed to Malacca in Malaysia, the most important east point in the trade network where Malay met Gujarati, Chinese, Japanese, Javanese, Bengali, Persian and Arabic traders, among others, described by Tomé Pires as of invaluable values. [29] the peninsula 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 was erected a strong gate which, called the "A Famosa", still remains. Knowing of Siamese ambitions over Malacca, Albuquerque sent immediately Duarte Fernandes on a diplomatic mission to the kingdom of Siam (modern Thailand), where he was the first European to arrive, establishing amicable relations between both kingdoms. In November that year, getting to know the location of the so-called "Spice Islands" in the Moluccas, he sent an expedition led by António de Abreu to find them, arriving in early 1512. Abreu went by Ambon while deputy commander Francisco Serrão came forward to Ternate, were 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 was followed the arrival in Guangzhou, where trade was established and later would be established Macau trade post.

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 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, before capturing Bahrain in 1521, when a force led by Antonio 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. With the regular maritime route linking Lisbon to Goa since 1497, the island of Mozambique become a strategic port, and there was built Fort São Sebastião and an hospital. In the Azores, the Islands Armada protected the ships 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. García Jofre de Loaísa expedition reached the Moluccas, docking at Tidore. The 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), atributting the Moluccas to Portugal and the Philippines to Spain.

In 1530, John III organized the colonization of 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, 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 on the coast, and São Paulo on the border of the altiplane. 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 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, Diu, Mumbai and Bassein. In 1538 the fortress of Diu is again surrounded by Ottoman ships. Another siege failed in 1547 puting an end to the Ottoman ambitions, confirming the 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 and other traders arrived in Japan for the first time. 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.. 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 for many years was the port from Japan to the world.

Portugal established trading ports at far-flung locations like Goa, Ormuz, Malacca, Kochi, the Maluku Islands, Macau, and 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. Jesuit missionaries, such as the Basque Francis Xavier, followed the Portuguese to spread Roman Catholic Christianity to Asia with mixed success.

In Brazil, deeming the capitanias system ineffective, Tomé de Sousa, the first Governor-General was sent in 1549. He built the capital of Brazil, Salvador at the Bay of All Saints. The first Jesuits arrived the same year. From 1565 through 1567 Mem de Sá, a Portuguese colonial official and the third Governor General of Brazil, successfully destroyed a ten year-old French colony called France Antarctique, at Guanabara Bay. He and his nephew, Estácio de Sá, then founded the city of Rio de Janeiro in March 1567.

In 1580, King Philip II of Spain invaded Portugal after a crisis of succession brought about by King Sebastian of Portugal's death during a disastrous Portuguese attack on Morocco in 1578. At the Cortes of Tomar in 1581, Philip was crowned Philip I of Portugal, uniting the two crowns and overseas empires under Spanish Habsburg rule in a dynastic Iberian Union. At Tomar Philip promised to keep the empires legally distinct, leaving the administration of the Portuguese Empire to Portuguese nationals, with a Spanish viceroy in Lisbon seeing to his interests.Boyajian, p. 11 All the Portuguese colonies accepted the new state of affairs except for the Azores, which held out for António, a Portuguese rival claimant to the throne who had garnered the support of Catherine de Medici of France in exchange for the promise to cede Brazil. Spanish forces eventually captured the island in 1583.

The union with Spain entailed both benefits and drawbacks as far as the Portuguese Empire was concerned. Spanish imperial trade networks were opened to Portuguese merchants, which was particularly lucrative for Portuguese slave traders who could now sell slaves in Spanish America at a higher price than could be fetched in Brazil. The Tordesillas line demarcating the boundary between Spanish and Portuguese control in South America was increasingly ignored by the Portuguese, who pressed beyond it into the heart of Brazil. However, the union meant that Spain dragged Portugal into its conflicts with England, France and the Dutch Republic, countries which were beginning to establish their own overseas empires. The primary threat came from the Dutch, who had been engaged in a struggle for independence against Spain since 1568. The Dutch took their fight overseas, attacking Spanish and Portuguese colonies and shipping. The Portuguese Empire, consisting primarily of exposed coastal settlements vulnerable to being picked off one by one, proved to be an easier target than the Spanish Empire.

The Dutch–Portuguese War began with an attack on São Tomé and Príncipe in 1597 and lasted until 1663. The war was waged by the Dutch East India Company (established in 1602) and its West India counterpart (1621), commercial ventures whose aim was to take over the trade networks that the Portuguese had established in Asian spices, West African slaves and Brazilian sugar In Asia, the Dutch captured the Spice Islands (1605), Malacca (1641), Colombo (1656), Ceylon (1658), Nagappattinam (1660), Cranganore and Cochin (1662). Although Goa, the capital of Portuguese Asia,

Diu and Macau were successfully defended, the expulsion of the Portuguese from Japan in 1639 excluded Portuguese merchants from the highly profitable China-Japan trade. Having successfully prevented the French from gaining a foothold in Portuguese Brazil at France Équinoxiale in 1615, Salvador da Bahia was lost to the Dutch in 1624 (though recaptured by a joint Spanish-Portuguese force the following year) and Pernambuco in 1630. In need of slaves for the sugar producing regions they had captured in Brazil, the Dutch began attacks on the Portuguese trading posts on the west coast of Africa, successfully taking Elmina (1638), Luanda (1641) and Axim (1642). By 1654, Portugal had succeeded in expelling the Dutch from Brazil and Luanda, though its preeminent position in Asia had been lost forever.

Imperial decline (1663–1822)

Ouro Preto, 18th century colonial city in Minas Gerais, Brazil.

The loss of colonies was one of the reasons that contributed to the end of the personal union with Spain. In 1640 John IV was proclaimed King of Portugal and the Portuguese Restoration War began. In 1668 Spain recognized the end of the Iberian Union and in exchange Portugal ceded Ceuta to the Spanish crown.

In 1661 the Portuguese offered Bombay and Tangier to England as part of a dowry, and over the next hundred years the British gradually became the dominant trader in India, providing the bases from which its empire would grow as the Moghul Empire disintegrated from the middle of the 18th century, gradually excluding the trade of other powers in the later 18th and early 19th centuries. Portugal was able to cling onto Goa and several minor bases through the remainder of the colonial period, but their importance declined as trade was diverted through increasing numbers of English, Dutch and French trading posts.

In 1755 Lisbon suffered a catastrophic earthquake, which together with a subsequent tsunami killed more than 100,000 people out of a population of 275,000. This sharply checked Portuguese colonial ambitions in the late 18th century.

Portuguese empire circa 1810.

Unlike Spain, Portugal did not divide its colonial territory in America. The captaincies created there were subordinated to a centralized administration in Salvador which reported directly to the Crown in Lisbon.

Encouraged by the example of the United States of America, which had won its independence from Britain (1776-1781), an attempt centred in the colonial province of Minas Gerais was made in 1789 to achieve the same objective. However, the Inconfidência Mineira failed, the leaders arrested and, of the participants of the insurrections the one of lowest social position, Tiradentes, was hanged.

In 1808, Napoleon Bonaparte invaded Portugal, and Dom João, Prince Regent in place of his mother, Dona Maria I, ordered the transfer of the royal court to Brazil. In 1815 Brazil was elevated to the status of Kingdom, the Portuguese state officially becoming the United Kingdom of Portugal, Brazil and the Algarves (Reino Unido de Portugal, Brasil e Algarves), and the capital was transferred from Lisbon to Rio de Janeiro, the only instance of a European country being ruled from one of its colonies. There was also the election of Brazilian representatives to the Cortes Constitucionais Portuguesas (Portuguese Constitutional Courts).

Although the royal family returned to Portugal in 1821, the interlude led to a growing desire for independence amongst Brazilians. In 1822, the son of Dom João VI, then prince-regent Dom Pedro I, proclaimed the independence, September 7, 1822, and was crowned emperor. Unlike the Spanish colonies of South America, Brazil's independence was achieved without significant bloodshed.

Portuguese Africa and the overseas provinces (1822–1961)

Fort Jesus, 16th Century Portuguese Fortress, Kenya.

At the height of European colonialism in the 19th century, Portugal had lost its territory in South America and all but a few bases in Asia. During this phase, Portuguese colonialism focused on expanding its outposts in Africa into nation-sized territories to compete with other European powers there. Portuguese territories eventually included the modern nations of Cape Verde, São Tomé and Príncipe, Guinea-Bissau, Angola, and Mozambique.

The Pink Map - Portugal's claim of sovereignty over the land between Portuguese Angola and Portuguese Mozambique.

Portugal pressed into the hinterland of Angola and Mozambique, and explorers Serpa Pinto, Hermenegildo Capelo and Roberto Ivens were among the first Europeans to cross Africa west to east. The project to connect the two colonies, the Pink Map, was the Portuguese main objective in the second half of the 19th century. However, the idea was unacceptable to the British, who had their own aspirations of contiguous British territory running from Cairo to Cape Town. The British Ultimatum of 1890 was imposed upon King Carlos I of Portugal and the Pink Map came to an end. The King's reaction to the ultimatum was exploited by republicans. In 1908 King Carlos and Prince Luís Filipe were murdered in Lisbon. Luís Filipe's brother, Manuel, become King Manuel II of Portugal. Two years later Portugal became a republic.

In World War I German troops threatened Mozambique, and Portugal entered the war to protect its colonies.
António de Oliveira Salazar, who took power in 1933, considered Portuguese colonies as overseas provinces of Portugal. In the wake of World War II, the decolonization movements began to gain momentum. In the Portuguese Empire the first major clash occurred in São Tomé in the Batepá massacre of 1953. The Cold War also created instabilities among Portuguese overseas populations, as the United States and Soviet Union tried to increase their spheres of influence. In 1954 India invaded Dadra and Nagar Haveli, and in 1961 Portuguese India came to an end when Goa, Daman and Diu were also invaded. Also in 1961 the tiny Portuguese fort of São João Baptista de Ajudá in Ouidah, a remnant of the West African slave trade, was taken by the new government of Dahomey (now Benin).

But, despite these losses and unlike the other European colonial powers, Salazar attempted to resist the tide of decolonization and maintain the integrity of the empire. As a result, Portugal was the last nation to retain its major colonies.

End of empire (1961–1999)

Portuguese colonies in the 20th century, dates represent loss of territory.

The rise of Soviet influence among the Movimento das Forças Armadas's military (MFA) and working class, and the cost and unpopularity of the Portuguese Colonial War (1961–1974), in which Portugal resisted to the emerging nationalist guerrilla movements in some of its African territories, eventually led to the collapse of the Estado Novo regime in 1974. Known as the "Carnation Revolution", one of the first acts of the MFA-led government which then came into power - the National Salvation Junta (Junta de Salvação Nacional) - was to end the wars and negotiate Portuguese withdrawal from its African colonies. These events prompted a mass exodus of Portuguese citizens from Portugal's African territories (mostly from Angola and Mozambique), creating over a million Portuguese refugees - the retornados. Portugal's new ruling authorities also recognized Goa and other Portuguese India's territories invaded by India's military forces, as Indian territories. Benin's claims over São João Baptista de Ajudá, were also accepted by the Portuguese, and diplomatic relations were restored with both India and Benin.

Civil wars in both independent Mozambique and Angola promptly broke out, with incoming communist governments formed by the former rebels (and backed by the Soviet Union, Cuba, and other communist countries) fighting against insurgent groups supported by nations like Zaire, South Africa, and the United States.

East Timor also declared independence at this time (1975), making an exodus of many Portuguese refugees to Portugal, also known as retornados. But was almost immediately invaded by neighbouring Indonesia, which occupied it until 1999. A United Nations-sponsored referendum that year resulted in East Timorese choosing independence, which was achieved in 2002.

The transfer of the sovereignty of Macau to China on December 20, 1999 under the terms of an agreement negotiated between People's Republic of China and Portugal twelve years earlier marked the end of the Portuguese overseas empire.

Legacy

Members of the Community of Portuguese Language Countries.

The seven former colonies of Portugal that are now independent nations with Portuguese as their official language, together with Portugal, are members of the Community of Portuguese Language Countries.
Today Portuguese is one of the world's major languages, ranked 6th according to number of native speakers (between 177 and 191 million). It is the language of about half of South America, even though Brazil is the only Portuguese-speaking nation in the Americas. It is also a major lingua franca in Portugal's former colonial possessions in Africa. It is an official language in eight countries, also being co-official with Cantonese Chinese in the Chinese special administrative region of Macau.

A legacy of Portuguese intermarriage in Malacca during its time as a Portuguese settlement is the Kristang people.
