Almagro, Diego d', born 1475, joined Pizarro, in 1525, in his first abortive attempt to penetrate into Peru, and afterwards shared with him in the conquest of that country, though jealousies had long since prevailed between the two leaders. Almagro was charged with murdering the Inca, Atahualpa. In 1534 he commenced the subjugation of Chili. A little later he rescued Pizarro's brothers from the Indians who besieged them at Cuzco, but when he was refused entrance into the city stormed it himself. Pizarro sent a force which defeated him and took him prisoner. After long incarceration he was strangled in 1538. His son avenged his death by killing Pizarro, but was himself executed at Cuzco in 1541.
