Ferdinand Magellan, the renowned Portuguese explorer, is best known for his expedition that resulted in the first circumnavigation of the Earth. Magellan undertook one significant voyage, which began in 1519 and ended in 1522.
This voyage was commissioned by Spain and aimed to establish a westward route to the Spice Islands (the Moluccas). Although Magellan did not complete the journey himself—he was killed in the Philippines in 1521—his fleet continued under the command of Juan Sebastián Elcano. The expedition ultimately returned to Spain, proving the massive scale of the Earth and opening up new routes for global trade.
In summary, while Magellan personally embarked on just one major expedition, it had profound implications for navigation and exploration, reshaping our understanding of the world.
