João Serrão

João Rodrigues Serrão, also known as Juan Rodríguez Serrano, was a Portuguese and Spanish pilot and explorer. He served in the Portuguese India Armadas that secured control of the Indian Ocean and the Strait of Malacca for the Portuguese but is most well known for his participation in Ferdinand Magellan's 1519–1521 expedition to the Spice Islands for Charles I of Spain, which discovered a path around South America to the Pacific and initiated Spanish involvement in the Philippines. Serrão and Duarte Barbosa became leaders of the expedition after Magellan's death at the Battle of Mactan but did not live to complete the circumnavigation with Elcano. They were both killed shortly thereafter during a massacre of the Spanish by their supposed convert and ally Humabon, raja of Cebu.
