History of Costa Rica History of Costa Rica The first natives in Costa Rica were hunters, and gatherers, and Costa Rica served as an intermediate region between Mesoamerican and Andean native cultures. In 1502, Christopher Columbus made landfall in Costa Rica. Soon after, his forces overcame the indigenous people. He incorporated the territory into the Captaincy General of Guatemala as a province of New Spain in 1524. For the next 300 years, Costa Rica was a colony of Spain.
