​ALMAGRO, DIEGO DE (1475–1538), Spanish commander, the companion and rival of Pizarro (q.v.), was born at Aldea del Rey in 1475. According to another account he was a foundling in the village from which he derived his name. In 1525 he joined Pizarro and Hernando de Luque at Panama in a scheme for the conquest of Peru (see Peru: History). He was executed by order of Pizarro in 1538 in consequence of a dispute as to their respective territories.
