Atahualpa
On the death of their father, the Emperor Huayna Capac, and their older brother, Ninan Cuyochi, who had been the heir, the empire was divided between the two surviving brothers, Huáscar and Atahualpa. Huascar got the major part of it with the capital Cusco, and Atahualpa the northern parts, including Quito (now the capital of Ecuador). For a couple of years, the two brothers reigned without problems. But Huascar demanded that Atahuallpa swear an oath to him. Atahuallpa refused, and the civil war began.
