Increasing Indian discontent with colonial rule sparked the great rebellion of Túpac Amaru II. Born José Gabriel Condorcanqui, this educated, Spanish-speaking Indian took the name of his ancestor, Túpac Amaru. During the 1770s, he became embittered over the harsh treatment of the Indians by the "corregidores de indios". In November 1780 Túpac Amaru II and his followers seized and executed a particularly cruel "corregidor de indios". Although Túpac Amaru II insisted that his movement was reformist and did not seek to overthrow Spanish rule, his demands included an autonomous region for natives. The uprising quickly became a full-scale revolt. Approximately 60,000 Indians in the Peruvian and Bolivian Andes rallied to the cause. After scoring some initial victories, including defeating a Spanish army of 1,200 men, Túpac Amaru II was captured and killed in May 1781; nonetheless, the revolt continued, primarily in Upper Peru. There, a supporter of Túpac Amaru II, the Indian chief Tomás Catari, had led an uprising in Potosí during the early months of 1780. Catari was killed by the Spaniards a month before Túpac Amaru II. Another major revolt was led by Julián Apaza, a sexton who took the names of the two rebel martyrs by calling himself Túpac Catari (also spelled Katari). He besieged La Paz for more than 100 days. Spain did not succeed in putting down all of the revolts until 1783 and then proceeded to execute thousands of Indians.
