Ferdinard Magellan (1480-1521) leaded the Spanish expedition that was able, for the first time, to circumnavigate around the Earth between 1519 and 1522. Magellan was not able to finish the trip as he died in a battle in Phillipines in 1521, and therefore the voyage was completed by another Spanish sailor called Juan Sebastian Elcano.
The initial aim of the Spanish King Charles I when organizing the expedition was to find a westward route to arrive to the Spice Islands, which was actually fulfilled.
