Inca Yupanqui being in Cuzco with the desire of ennobling it, he determined to go to Colla-suyu, which includes the provinces to the southward of the city, because he had received intelligence that the descendants of Zapana, who reigned in Hatun-colla, were very proud and powerful, and that they had assembled forces to march upon Cuzco. So he ordered his people to prepare. The Indians relate that many men had arrived for the campaign which Inca Yupanqui wanted to undertake, and, being on the point of setting out, some captains of Condesuyo, with their warriors, plotted amongst themselves to kill the Inca. For they said that if he returned victorious, he would be in such high estimation that he would desire to bring all men under vassalage and servitude. At the time when the Inca was engaged in his festivities, and somewhat joyous from the quantity of wine he had drunk, one of the conspirators approached and delivered a blow with a stick on the royal head. The Inca, disturbed and excited, rose up saying, “What do you do, traitor?” By this time, the men of Condesuyos had killed many persons, and the Inca himself thought of seeking safety in the temple. But it was of no avail to think, for he was overtaken by his enemies and killed, with many of his women.

There was great confusion in the city, insomuch that one man could not understand another. The priests had retired to the temple, and the women tore their hair, horrified at the death of the Inca by bloodshed, as if he had been some vile person.
