Ferdinand Magellan was born in Portugal in 1480 and embarked on his first major voyage at age 25 with the Portuguese navy. He had a disagreement with his commanding officer and left Portugal, renouncing his citizenship. He convinced King Charles I of Spain to fund a voyage to reach the Spice Islands by sailing west. In 1521, Magellan led the expedition that became the first to sail across the Pacific Ocean through the straits now named after him. However, Magellan was killed in the Philippines before the voyage was completed. One of his ships, the Victoria, eventually returned to Spain with 18 survivors, having been the first to circumnavigate the globe.
