Magellan's expedition became historically significant for what reason?

Magellan's expedition is historically significant because it achieved the first successful circumnavigation of the globe. This monumental journey provided crucial evidence that the Earth is round and offered a new understanding of global geography. By sailing westward from Spain in search of a western route to the Spice Islands, the expedition faced numerous challenges, including treacherous seas, conflicts with indigenous peoples, and the loss of ships and crew. Although Magellan himself did not complete the journey, as he was killed in the Philippines, the remnants of his fleet continued the voyage and ultimately returned to Spain in 1522, thus successfully completing the first full voyage around the world. This expedition significantly impacted exploration, trade routes, and the relationship between different parts of the world during that period, making it historically important.
