Sapa

The Sapa Inca (Hispanicized spelling) or Sapa Inka (Quechua for "the only Inca"), also known as Apu ("divinity"), Inka Qhapaq ("mighty Inca"), or simply Sapa ("the only one"), was the ruler of the Kingdom of Cusco and, later, the Emperor of the Inca Empire (Tawantinsuyu) and the Neo-Inca State. While the origins of the position are mythical and tied to the legendary foundation of the city of Cusco, historically it seems to have come into being around 1100. The position was hereditary, with son succeeding father. The emperor was viewed as a god. The principal wife of the Inca was known as the Coya. There were two known dynasties, led by the Hurin and Hanan moieties respectively. The latter was in power at the time of Spanish conquest. The last effective Sapa Inca of Inca Empire was Atahual
