Diego de Almagro
Spanish conquistador (1475–1538)

Diego de Almagro, also known as El Adelantado and El Viejo, was a Spanish conquistador known for his exploits and killings in western South America. He participated with Francisco Pizarro in the Spanish conquest of Peru. While subduing the Inca Empire he laid the foundation for Quito and Trujillo as Spanish cities in present-day Ecuador and Peru, respectively. From Peru, Almagro led the first Spanish military expedition to central Chile. Back in Peru, a longstanding conflict with Pizarro over the control of the former Inca capital of Cuzco erupted into a civil war between the two bands of conquistadores. In the battle of Las Salinas in 1538, Almagro was defeated by the Pizarro brothers and months later he was executed.
