Which nationality was Ferdinand Magellan?

Ferdinand Magellan (c. 1480 – 27 April 1521) was a Portuguese explorer who organised the Spanish expedition to the East Indies from 1519 to 1522, resulting in the first circumnavigation of the Earth, completed by Juan Sebastián Elcano.

Born into a family of minor Portuguese nobility in around 1480, Magellan became a skilled sailor and naval officer and was in service of the Portuguese crown in Asia. After King Manuel I of Portugal refused to support his plan to reach India by a new route, by sailing around the southern end of America, he was eventually selected by King Charles I of Spain to search for a westward route to the Maluku Islands (the "Spice Islands"). Commanding a fleet of five vessels, he headed south through the Atlantic Ocean to Patagonia, passing through the Strait of Magellan into a body of water he named the "peaceful sea" (the modern Pacific Ocean). Despite a series of storms and mutinies, the expedition reached the Spice Islands in 1521 and returned home via the Indian Ocean to complete the first circuit of the globe. Magellan did not complete the entire voyage, as he was killed during the Battle of Mactan in the Philippine islands in 1521.

Magellan had already reached the Malay Archipelago in Southeast Asia on previous voyages traveling east (from 1505 to 1511–1512). By visiting this area again but now travelling west, Magellan achieved a nearly complete personal circumnavigation of the globe for the first time in history.
