Before the arrival of the Spaniards, the Inca Empire was involved in a civil war. The untimely death of both the heir Ninan Cuchi and the Emperor Huayna Capac, from a European disease that spread into Ecuador, created a power vacuum between two factions. The northern faction headed by Atahualpa claimed that Huayna Capac gave a verbal decree before his death about how the empire should be divided. He gave the territories pertaining to present-day Ecuador and northern Peru to his favorite son Atahualpa, who was to rule from Quito; and he gave the rest to Huáscar, who was to rule from Cuzco. He willed that his heart be buried in Quito, his favorite city, and the rest of his body be buried with his ancestors in Cuzco.
