Answer:
At the time of the Spanish Conquest the two leaders of the Incan Empire were Atahualpa and Huascar.
Explanation:
Atahualpa and Huascar were allegedly stepbrothers, their father was the great Incan leader Huayna Capac who they say died of smallpox. As the Spanish arrived and started the Conquest of what is today Peru they landed in the middle of an Incan civil war that had Huascar and his supporters based in Cusco and Atahualpa based in the North where his father had been reigning. Huascar was allegedly killed by Atahualpa's orders because Atahualpa planned to ransom his own release with gold for the Spanish, and Huascar was trying to do the same. Eventually, Atahualpa is betrayed despite providing ransom and killed by the Spanish in Cajamarca. The Spanish name another stepbrother and son of Huayna Capac, Manco Capac II as the Emperor to succeed after Atahualpa. Manco Capac II eventually rebels against the Spanish and retreats from Cusco to Vilcabamba. Vilcabamba is the last site of Incan resistance to Spanish encroachment in the early colonial years.
