Ferdinand Magellan was a Portuguese explorer born in 1480 who led the first expedition to circumnavigate the globe between 1519 and 1522. Though he was killed in the Philippines in 1521, Magellan's voyage established that the Earth was indeed round and proved valuable for increasing trade and knowledge of geography, as his expedition was the first to sail from the Atlantic Ocean into the Pacific Ocean, which he named. Motivated by both wealth and curiosity, Magellan explored on behalf of Portugal and later Spain.
