This celebrated man was a Portuguese noble who had received the most complete education in the palace of King John II. Having studied mathematics and navigation, at an early age he joined the Portuguese fleet which left for India in 1505 under the command of Almeida. He was present at the siege of Malacca under the famous Albuquerque, and accompanied another expedition to the rich Moluccas, or Spice Islands, when the Islands of Banda, Tidor, and Ternate were discovered. It was here he obtained the information which led him to contemplate the voyage which he subsequently realized. On his return to Portugal he searched the Crown Archives to see if the Moluccas were situated within the demarcation accorded to Spain. [14] In the meantime he repaired to the wars in Africa, where he was wounded in the knee, with the result that he became permanently lame. He consequently retired to Portugal, and his companions in arms, jealous of his prowess, took advantage of his affliction to assail him with vile imputations. The King Emmanuel encouraged the complaints, and accused him of feigning a malady of which he was completely cured. Wounded to the quick by such an assertion, and convinced of having lost the royal favour, Maghallanes renounced for ever, by a formal and public instrument, his duties and rights as a Portuguese subject, and henceforth became a naturalized Spaniard. He then presented himself at the Spanish Court, at that time in Valladolid, where he was well received by the King Charles I., the Bishop of Burgos, Juan Rodriguez Fonseca, Minister of Indian Affairs, and by the King's chancellor. They listened attentively to his narration, and he had the good fortune to secure the personal protection of His Majesty, himself a well-tried warrior, experienced in adventure. The Portuguese Ambassador, Alvaro de Acosta, incensed at the success of his late countryman, and fearing that the project under discussion would lead to the conquest of the Spice Islands by the rival kingdom, made every effort to influence the Court against him. At the same time he ineffectually urged Maghallanes to return to Lisbon, alleging that his resolution to abandon Portuguese citizenship required the sovereign sanction. Others even meditated his assassination to save the interests of the King of Portugal. This powerful opposition only served to delay the expedition, for finally the King of Portugal was satisfied that his Spanish rival had no intention to authorize a violation of the Convention of Demarcation.
