Condorcanqui's interest in the Native American cause had been spurred by the re-reading of one the "Royal Commentaries of the Incas", a romantic and heroic account of the history and culture of the ancient Incas. The book was outlawed at the time by the Lima viceroy for fear of it inspiring renewed interest in the lost Inca culture and inciting rebellion. The marquis's native pride coupled with his hate for the Spanish colonial system, caused him to sympathize and frequently petition for the improvement of native labor in the mills, farms and mines; even using his own wealth to help alleviate the taxes and burdens of the natives. After many of his requests for the alleviation of the native conditions fell on deaf ears, Condorcanqui decided to organize a rebellion. He began to stall on collecting reparto debts and tribute payments, for which the Tinta "corregidor" and governor Antonio de Arriaga threatened him with death. Condorcanqui changed his name to Túpac Amaru II and claimed he was descended from the last Inca ruler, Túpac Amaru.
