Castilla de Oro

1513 CE – 1538 CE (approx.) · capital Panamá

Spain's first mainland colony in the Americas, on the Isthmus of Panama, from which the Pacific was reached and the conquest of Peru launched.

Origins

Vasco Núñez de Balboa founded Santa María la Antigua del Darién in 1510 and crossed the isthmus to sight the Pacific in 1513. That year the Crown named the region Castilla de Oro and appointed Pedrarias Dávila as governor; he arrived in 1514 with a large expedition.

Rule and society

Pedrarias ruled harshly, raiding indigenous communities for gold and slaves. Rivalry with Balboa ended with Balboa's execution in 1519. That year Pedrarias founded Panamá on the Pacific coast, which became the capital. Expeditions from Panama conquered Nicaragua in 1524 and, under Francisco Pizarro, set out for Peru.

Decline and legacy

The indigenous population of the isthmus collapsed. In 1538 the Real Audiencia of Panama was created, replacing the governorship as the main authority on the isthmus.
