What caused the civil war that ensued from 1525-1532 after the death of Inca emperor?

The civil war from 1525 to 1532 following the death of Inca Emperor Huayna Capac was primarily caused by a succession crisis. Huayna Capac's death led to a power struggle between his sons, Atahualpa and Huáscar, as they vied for control over the vast Inca Empire. This internal conflict weakened the empire, making it more vulnerable to Spanish Conquistadors, who ultimately exploited the division to conquer the Inca territory. The war not only intensified the struggle for power but also destabilized the empire, facilitating the Spanish invasion.
