With the arrival from Spain in 1532 of Francisco Pizarro and his entourage of mercenaries or Conquistadores, the Inca empire was seriously threatened for the first time. Duped into meeting with the conquistadors in a peaceful gathering, an Inca emperor, Atahualpa, was kidnapped and held for ransom. After paying over $50 million in gold by today's standards, Atahualpa, who was promised to be set free, was strangled to death by the Spaniards who then marched straight for Cuzco and its riches.
