Answer
Executed, Diego de Almagro met his demise after a power struggle with Francisco Pizarro, his former ally in the conquest of Peru. Almagro's ambitions to rule the southern part of the Inca Empire clashed with Pizarro's authority, leading to a civil war. Defeated in the Battle of Las Salinas, Almagro was captured and sentenced to death by Pizarro's brother, Hernando.
