Ferdinand Magellan ( 1480-1521) was born in Portugal.
He found that no one wanted to employ him, so he offered his services to the king of Spain, setting out an ambitious plan to reach the Spice Islands of Indonesia by sailing west instead of east—somethingwhich had never been done before.
He left Spain in 1519 with five ships and 265 men. In this harsh journey, all but one of the ships was lost and most of the men died.
Magellan himself was killed in a fight with the natives in the Philippines in 1521.Finally, in 1522, one of the ships was ableto return to Spain with less than twentymen aboard.
