Explored Puerto Rico
He might have started his exploration career in 1493 as a member of Christopher Columbus's second voyage to the New World.
When Ponce Leon was governor of the eastern province of Hispaniola, he made the decision to explore a nearby island that would later become known as Puerto Rico. When it was discovered, it was loaded with gold. Ponce de León explored and colonized Puerto Rico in 1508–1509 after receiving repeated reports that gold might be discovered there. He founded Caparra, the colony's first settlement, close to the present-day city of San Juan. He afterwards went back to Hispaniola and was appointed governor of Puerto Rico, but was quickly ousted from office due to rivals' political scheming. Juan returned to the King of Spain following the discovery, where he investigated and settled the island.
The US territory of Puerto Rico is unorganized and is situated in the northeastern Caribbean Sea. There is one main island and numerous smaller ones, like Culebra, Vieques, and Mona. During the time of Christopher Columbus, it was colonized.
