Last legitimate Inca to rule

Túpac Amaru was the last legitimate Inca to rule (in the Vilcabamba region as the Neo-Inca State). With the death of his elder brother Titu Cosi, he ordered the execution of all Spanish people living in Vilcabamba and led an unsuccessful and poorly planned rebellion against the colonists. This resulted in his death and the end of Incan sovereignty, for Vilcabamba was occupied and the survivors enslaved.
