Pablo Zárate Willka (died 1905), also known as Willka ("sun" in Aymara), was an indigenous Bolivian caudillo who supported federalism in defense of indigenous autonomy. He was an officer in the Bolivian army, reaching the rank of colonel, and led one of the largest indigenous rebellions in the history of Bolivia. His campaign against the Bolivian government sought land reform for the Aymara and other indigenous communities and led the resistance against the system known as "latifundium". Working together with José Manuel Pando, they formed an alliance built on mutual need and respect. Willka, a literate Aymara leader and indigenous caudillo, showed signs of success as a politician and a military leader. His political ties with kinship and local communities gave him an edge over his adversaries in the altiplano.
