Final answer:
Spanish explorer Ferdinand Magellan led the first expedition around the world but was killed before completing it. His crew, however, managed to finish the journey under the leadership of Juan Sebastian Elcano.
Step-by-step explanation:
The Spanish explorer who led the first expedition around the world was Ferdinand Magellan, although he was killed during the expedition and did not complete the journey himself. After setting out in 1519, Magellan's expedition faced various obstacles including starvation, diseases and conflict with native tribes. Magellan himself was killed in the Philippines in 1521 during a conflict with local people. Nevertheless, his crew managed to continue the expedition and completed the first circumnavigation of the globe under the leadership of Juan Sebastian Elcano in 1522.
