In 1513 Juan Ponce de Leon (c. 1 4 60-1521), who had been with Christopher Columbus on his second voyage and had later been governor of Porto Rico, obtained a royal grant authorizing him to discover and settle " Bimini," - a fabulous island believed to contain a marvellous fountain or spring whose waters would restore to old men their youth or at least had wonderful curative powers.
The constitution of Porto Rico is contained in an act of the Congress of the United States (the Foraker Act) which came into operation in May 1900.
About 1520 Caparra was abandoned for a more healthy site, and the city of San Juan de Puerto Rico was founded as the capital of the eastern district.
The buccaneers or filibusters, who during the 17th century were drawn to the West Indies by the prospect of plundering the possessions of decadent Spain, often invaded Porto Rico, but that island escaped the conquest which Haiti experienced.
The unsettled political condition of Spain during the next forty years was reflected in the disturbed political conditions of Porto Rico and Cuba.
