As early as 1569, Governor Perafán de Rivera gave extensive plots of land, Indians included, in Matina to aristocrats (hidalgos) that helped to finance and support early conquest. Because these aristocrats found out that only a few Indians were available to exploit, they acquired African slaves to plant these lands with cocoa trees (the only feasible crop in these lands). These lands provided the only source of income to the absentee owners from the capital city of Cartago. Matina gained importance because of the cacao and the presence of African slaves, which made them attractive to pirate incursions.
