alongside its military and trade outposts, at the height of the reign of King John III of Portugal.
Luso-African relations In John III's time, trade between the Portuguese and Africans was extremely intense in
feitorias such
Arguim,
Mina,
Mombasa,
Sofala or
Mozambique. Under John III, several expeditions started in coastal Africa and advanced to the interior of the continent. These expeditions were formed by groups of
navigators,
merchants, adventurers and
missionaries. Missions in Africa were established by the College of Arts of Coimbra. The objective was to increase the king's
dominion, develop peaceful relations and to
Christianize the
indigenous peoples. Relations with local rulers were often complicated by trade in
slaves, as shown by John's correspondence with them. John III refused to abandon all of the Portuguese North African strongholds, but he had to make choices based on the economic or strategic value of each possession. John III decided to leave
Safim and
Azamor in 1541, followed by
Arzila and
Alcácer Ceguer in 1549. The fortresses of
Ceuta,
Tangiers and
Mazagan were strengthened "to face the new military techniques, imposed by the generalization of heavy artillery, combined with light fire weapons and blades". John III's
court jester was
João de Sá Panasco, a black African, who was eventually admitted to the prestigious
Order of Saint James based on his service in the
Conquest of Tunis (1535).
Luso-Asian relations asking King John III for the Evangelization of Asia'';
Avelar Rebelo, 1635. Before the reign of John III, the Portuguese had already reached
Siam (1511), the
Maluku Islands (1512), the Chinese littoral (1513),
Canton (1517) and
Timor (1515). During John's rule the Portuguese reached Japan, and at the end of John's reign
Macau was offered to Portugal by China. From India, John III imported an amazing variety of spices, herbs, minerals, and fabrics; from Malacca, exotic woods and spice; from Bengala, fabrics and exotic foodstuffs; from Alexandria and Cairo, exotic woods, metals, minerals, fabrics, and boullion; and from China, musk, rhubarb and silk in exchange for gromwells, pearls, horses from Arabia and Persia, non-worked silk, silk embroidery threads, fruits of the date palm, raisins, salt, sulphur and many other goods. As Muslims and other peoples constantly attacked Portuguese
fleets in India, and because it was so far away from mainland Portugal, it was extremely difficult for John III to secure Portuguese dominion in this area. A
viceroy (or Governor-General with extensive powers) was nominated, but it was not enough to defend the Portuguese possessions in India. The Portuguese started by creating
feitorias – commercial strongholds in
Cochin,
Cannanore,
Coulão,
Cranganore and Tanor – with the initial objective of establishing just a commercial dominion in the region. The hostility of many Indian kingdoms and alliances between
sultans and
zamorins with the intent of expelling the Portuguese made it necessary for the Europeans to establish a
sovereign state. Portugal thus militarily occupied some key cities on the Indian coast and Goa became the headquarters of the Portuguese Empire in the East as of 1512. Goa became a starting point for the introduction of European cultural and religious values in India, and churches, schools and hospitals were built. Goa remained an overseas possession of Portugal until
India reclaimed it in 1961. The Portuguese arrived in Japan in 1543. Japan had been known in Portugal since the time of
Marco Polo, who called it "Cipango". Whether Portuguese nationals were the first Europeans to arrive in Japan is debated. Some say the first Portuguese arrival was the writer
Fernão Mendes Pinto, while others say it was the navigators António Peixoto,
António Mota, and
Francisco Zeimoto. Portuguese traders started negotiating with Japan as early as of 1550 and established a base there in
Nagasaki. By then, trade with Japan was a Portuguese monopoly under the rule of a
captain. Because the Portuguese established themselves in Macau, Chinese commercial relations and the silver trade with Japan were improved under John III's rule. After the voyage of
Ferdinand Magellan, the
Crown of Castile claimed the recently discovered
Maluku Islands. In 1524, a conference of experts (
cartographers,
cosmographers, pilots, etc.) was held to solve the dispute caused by the difficulty of determining the
meridian agreed to in the
Treaty of Tordesillas. The Portuguese delegation sent by John III included names such as António de Azevedo Coutinho,
Diogo Lopes de Sequeira,
Lopo Homem and Simão Fernandes. The dispute was settled in 1529 by the
Treaty of Zaragoza, signed by John III and Charles I of Spain. The Portuguese paid 350,000 gold
ducados to Spain and secured their presence in the islands, which was not actually necessary, since Portugal was actually entitled to the islands according to the Treaty of Tordesillas. In 1553, Leonel de Sousa obtained authorization for the Portuguese to establish themselves in Canton and Macau. Macau was later offered to John III as a reward for Portuguese assistance against
maritime piracy in the period between 1557 and 1564.
Portuguese America During the reign of King John III the Portuguese Empire established itself in South America with the foundation of the twelve
Captaincy Colonies of Brazil (from 1534 onwards). Each with its own
donatary captain, the twelve colonies worked independently. In 1549, John III established the
Governorate General of Brazil, and the twelve captaincy colonies became subordinate to it. The first Governor-General appointed by John III,
Tomé de Sousa, founded the city of
Salvador, Bahia (São Salvador da Bahia de Todos os Santos) in 1549. For his role in the colonization of South America, John III has been referred to as The Colonizer (
Portuguese: "o Colonizador"). Immediately following the discovery of Brazil in 1500, the Portuguese imported
brazilwood, Indian slaves and exotic birds from there. Brazilian wood was a very appreciated product in Europe because it could be used to produce a type of red dye. During John III's rule, after the initial
colonization, Portuguese explorers intensified the search for brazilwood and began the cultivation of
sugarcane, which was well suited to the climate of Brazil and especially around
Recife and
Bahia. In the final years of John's reign Portugal's colony of Brazil was just beginning its rapid development as a producer of sugar that compensated for the gradual decline of revenues from Asia, a development that would continue during the reign of his grandson and successor,
Sebastian (1557–1578). Since Brazil lacked a large native population and the ones who lived there weren't adapted to the strenuous work required in the plantation fields, the Portuguese colonists began importing African slaves to strengthen the workforce present in the territory. The first slaves, from the region of
Guinea, arrived in Brazil in 1539. Most of them worked in the sugarcane fields or served as house servants. ==Death and dynastic issue==
