"Substantially due to the quality and excellence of the horses bred on the island, Puerto Rico played a very important role in the colonization of the New World. In 1521 Ponce de Léon obtained fifty horses for his search of the fountain of youth. In the same time period Francisco Pizarro bought horses needed for the conquest of South America in Puerto Rico and a Don Gaspar Troche imported stock from Puerto Rico for his horse business in Mexico. After the collapse of a short gold rush, horses became the principal export product of Puerto Rico and thousands were shipped to the New World to satisfy the growing demand.
