Atahualpa, ah'ta wahl'pa, the last of the Incas, succeeded his father in 1529 on the throne of Quito, while his brother Huascar obtained the kingdom of Peru. They soon made mar against each other; the latter was defeated and his kingdom fell into the hands of Atahualpa, who took terrible vengeance on his opponents. At this juncture the Spaniards under Pizarro appeared and by a trick seized Atahualpa, who offered a vast ransom in gold. Huascar offered a greater sum, and Atahualpa in retaliation caused his brother to be killed. Pizarro secured the ransom and then, after accusing Atahualpa of treason, had him quickly tried and executed. See INCA; PIZARRO, FRANCISCO.
