Ferdinand Magellan sought to prove that the spice islands could be reached by a western route.

Explanation:

Ferdinand Magellan was a Portuguese explorer that believed the spice islands could be reached by the west sea if the world was surrounded. So, he started a trip with 5 ships from Spain to explore the sea and reach the islands. He died in the attempt but the quest was successful thanks to his contributions and records. And after three years the 18 remaining members of the fleet reached home to show them the Magallan stretch. He was the first European to cross the pacific ocean.
