Tupac and his supporters, at or after…

Tupac and his supporters, at or after a party on November 4, 1780, in Tungasuca, where Túpac is cacique, seize Antonio Arriaga, the corregidor of his hometown of Tinta, hold him for six days, then publicly execute him.

Before executing Arriaga, Túpac convinces Arriaga to ask a number of Spaniards to bring money to him, under the pretext of ransoming him.

Túpac begins moving through the countryside, where he gains supporters, primarily from the Indian and mestizo classes, but also with some Criollos (locals of mostly Spanish descent).

He arrives on November 17 at the town of Sangarará, where Spanish authorities from Cuzco and the surrounding area have assembled a force of about nine hundred.

Túpac's ad hoc army, which has grown to several thousand, routs this force the next day, destroying the local church where a number of people had taken refuge.
