Cusi Chimbo
Chronicles describe Cusi Chimbo as a daughter of an Ayarmaca lord, given to the Sapa Inca Cápac Yupanqui as a concubine who became his second wife. She was the mother of Inca Roca.
Around 1350, the same chronicles relate, she poisoned Cápac Yupanqui at Cusco: his death let her son's Hanan Cusco faction storm the Inticancha palace, overthrow the Hurin dynasty and place Inca Roca on the throne, founding the Hanan dynasty.
