In 1774, a mob of commoner Andeans in one town in the viceroyalty of Peru attacked and killed their cacique, claiming that no person could be held responsible because the común, the community of commoners, had done it. The political theory was simple: if the cacique is good, he should be obeyed, but if he is a tyrant, if he does not serve justice, the people of the community have a right to overthrow him. A synthesis of pre-Columbian practices, religious teachings, and Spanish political philosophy, it was taught by officers in the cabildo and cofradías of the town. Also known as the rey común, Andeans defined it as “the ayllus together.” In testimony and written petitions, comuneros defended their right to overthrow their cacique, while professing loyalty to the Crown by paying tribute and serving mita. This idea of commoner self-government spread to other indigenous towns.
