King Pachacutec was the king of the Incan Empire for a time. He was the fourth in the Hanan dynasty ( In the Incan culture, rule was passed from father to son. Pachactuec had two sons himself; they were named Amaru Yupanqui, and Tupac Inca Yupanqui. Usually, the older son is chosen to be the next ruler; however, this is not the case with Pachacutec’s two sons.

The Incan culture dwelled on the warriors. Being strong and courageous was held in high esteem. Pachacutec felt that he wanted a warrior to rule after him. To him, Amaru was not a warrior and Tupac was then chosen to be the next ruler.

Pachacutec was not supposed to be the next ruler. However, during a battle with an enemy tribe, he was able to demonstrate his talent. His father saw that he, Pachacutec was a true warrior and could lead the empire. Therefore, Pachacutec was chosen to be the next emperor of the Incan Empire.
