Manco initially worked as a puppet ruler from the Cuzco branch of the Inca royal family of Huayna Capac, having challenged Atahualpa and the northern tribes from Quito in the Inca Civil War. He later turned against his Spanish lords and made rebellion, was captured in a failed escape attempt but later released. Once free, Manco endeavored to free his land from the Spaniards. Attempting to regain the Inca capital of Cuzco in a ten-month siege in 1536, he failed, and despite a victory over conquistador Francisco Pizarro's brother Hernando at Ollantaytambo in January 1537, he had to withdraw.
