Ferdinand Magellan was a Portuguese explorer who organized the Spanish expedition to the East Indies from 1519 to 1522, resulting in the first circumnavigation of the Earth. Magellan sought a western route to the 'Spice Islands' (Maluku Islands). Although he was killed in the Philippines during the Battle of Mactan, one of his ships, the 'Victoria,' completed the journey under the command of Juan Sebastián Elcano. The expedition proved that the Earth was much larger than previously thought and that all its oceans were connected. Magellan also gave the Pacific Ocean its name, 'Mar Pacífico' (Peaceful Sea), due to its calm waters upon his arrival.
