The death of Huayna Capac in 1525 left the Inca Empire divided between his sons. Huáscar inherited the larger domain while Atahualpa controlled the northern region around Quito. Tensions escalated when Atahualpa sought to expand his smaller share, prompting Huáscar to launch a military campaign that initially captured Cajamarca and took Atahualpa prisoner.
After escaping captivity, Atahualpa allied with the experienced Inca generals Quizquiz and Chalicuchima. Together they engaged Huáscar's forces near Chimborazo. Despite holding a numerical advantage, Huáscar's army was defeated and driven back. The Inca commander Atoc was captured during the battle and reportedly executed in a gruesome manner, while Ullco Colla, lord of Tumipampa, was killed in the fighting.
The defeat gravely undermined the foundations of Huáscar's power. Within a year, his remaining dominance collapsed entirely at the Battle of Quipaipan, allowing Atahualpa to consolidate control over the whole Inca Empire. This internal conflict left the empire weakened at the very moment Spanish conquistadors under Francisco Pizarro were advancing into Inca territory.
