Ferdinand Magellan led a fleet of five ships on an expedition to explore a western route to the Spice Islands in 1519. The expedition faced many hardships including mutiny, storms that destroyed one ship, lack of food, and disease that killed most of the crew. Only 18 crew members survived to return on the single remaining ship, though Magellan did not survive as he was killed in the Philippines in 1521. The expedition proved that the world was round and was the first to circumnavigate it, starting a debate on territorial claims in Southeast Asia.
