Step-by-step explanation:
The first person to circumnavigate the world was Ferdinand Magellan, a Portuguese explorer. However, it's important to note that Magellan himself did not complete the entire journey. He set out on an expedition in 1519 with a fleet of five ships and a crew of about 270 men. They sailed from Spain, crossed the Atlantic Ocean, and eventually entered the Pacific Ocean through the southern tip of South America. Magellan was killed in the Philippines in 1521.
The expedition was continued by one of his subordinate commanders, Juan Sebastián Elcano, and the remaining crew members. They sailed across the Indian Ocean, rounded the Cape of Good Hope at the southern tip of Africa, and eventually returned to Spain in 1522. This completion of the circumnavigation of the world marked a significant milestone in the Age of Exploration.
