Statue of Juan Ponce de Leon

In 1512, Ponce de León founded the first settlement in Puerto Rico, Caparra. He was greeted with open arms by the Taino Cacique Agüeybaná and quickly gained control of the island. As a result, Ponce de León was named Governor of Puerto Rico in 1509. Ponce de León and the other conquistadors forced the Tainos to work in the mines and to construct fortifications. The Tainos died in great numbers after exposure to the European diseases the sailors brought with them, to which they had no immunity. Ponce de León, however, became rich while serving as Governor.

Ponce de León equipped three ships at his own expense, and set out on his voyage of discovery and conquest in 1513. On March 27, 1513, he sighted an island, but sailed on without landing. On April 2 he landed on the east coast of the newly "discovered" land at a point which is disputed, but was somewhere on the northeast coast of the present State of Florida. Ponce de León claimed "La Florida" for Spain. He named the land La Florida, meaning flowery, either because of the vegetation in bloom he saw there, or because he landed there during Pascua Florida, Spanish for Flowery Passover, meaning the Easter season
