Christopher Columbus discovered the Caribbean islands while Ferdinand Magellan was the first to circumnavigate the earth.
Explanation:
Christopher Columbus was the earlier one of the two great explorers and his exploration was to the west of Spain where he eventually discovered the Caribbean islands and led o the discovery of the Americas.
Ferdinand Magellan was also a very ambitious sailor and he tried to circumnavigate the earth with his expedition of six ships.
HE did this around 1520 and was eventually successful and in the process had discovered the Magellan straights too.
Maybe the better question to ask him is why he appointed his own bishop when the Pope is who does that. Why he thought could be more than the leader of the Church. What he intended, and why he turned back on his actions.
