the "Spice Islands" in the Moluccas, where he remained. He married a woman from Amboina and became a military advisor to the Sultan of Ternate, Bayan Sirrullah. His letters to Magellan later proved decisive, giving information about the spice-producing territories. After taking a leave without permission, Magellan fell out of favour. Serving in Morocco, he was wounded, resulting in a permanent limp. He was accused of trading illegally with the Moors. The accusations were proven false, but he received no further offers of employment after 15 May 1514. Later in 1515, he was offered employment as a crew member on a Portuguese ship, but rejected this. In 1517, after a quarrel with Manuel I of Portugal, who denied his persistent requests to lead an expedition to reach the Spice Islands from the east (i.e., while sailing westwards, thus avoiding the need to sail around the tip of Africa), he left for Spain. In Seville he befriended his countryman Diogo Barbosa and soon married the daughter of Diogo's second wife, Maria Caldera Beatriz Barbosa. They had two children: Rodrigo de Magallanes and Carlos de Magallanes, both of whom died at a young age. His wife died in Seville around 1521. Meanwhile, Magellan devoted himself to studying the most recent charts, investigating, in partnership with cosmographer Rui Faleiro, a gateway from the Atlantic to the South Pacific and the possibility that the Moluccas were Spanish under the demarcations of the Treaty of Tordesillas. Voyage of circumnavigation Background and preparations After having his proposed expeditions to the Spice Islandsthe Moluccas beside New Guinearepeatedly rejected by King Manuel I of Portugal, Magellan renounced his Portuguese nationality and turned to Charles I, the young king of Spain (later emperor CharlesV of the Holy Roman Empire). Under the terms of the 1494 Treaty of Tordesillas, Portugal was to control the eastern routes to Asia that went around the Cape of Good Hope in Africa. Magellan instead proposed to seek a southwestern passage around South America to reach the Spice Islands by a western route, a feat never before accomplished. Bergreen further states that Magellan claimed to Charles that his Malaccan or Sumatran slave Enrique had been a native of the Spice Islands and used Enrique and letters from Serrão to "prove" that the islands were so far east that they would fall within the Spanish sphere of influence if the world were truly to be divided
