Huayna Capac
Huayna Capac relied on his sons to support his reign. While he had many legitimate and illegitimate children (legitimate meaning born of his sister-wife, under the Inca system), two sons are historically important. Prince Túpac Cusi Hualpa, also known as Huáscar, was the son of Coya Mama Rahua Occllo of the royal line. The second was Atahualpa, an illegitimate son who was likely born of a daughter of the last independent King of Quitu, one of the states conquered by Huayna Capac during the expansion of the Inca Empire. These two sons would play pivotal roles in the final years of the Inca Empire.
