Conflicts between conquistadors and rebellions End of the Neo-Inca state After the assassination of Francisco Pizarro, in retaliation for his father's execution in 1538, Diego de Almagro II, El Mozo, continued to press claims as the rightful ruler of Peru and as leader of his father's supporters.

Desperate not to face the same fate as his father after the battle of Las Salinas, Diego de Almagro II gathered an army of supporters.

Vaca de Castro's forces killed 200 Almagristas, and hanged many more later that day.

[1] De Almagro fled to Cuzco and tried to seek refuge at Manco Inca's residence in Vitcos.

But he was caught on September 16, 1542 and was executed on the city plaza of Cuzco after a brief trial.
