Tupac Yupanqui was perhaps an even greater soldier than his father. He annexed much of the land of modern southern Ecuador and northern Peru. First he conquered the Canari tribe, built roads, forts, palaces and temples and incorporated their territory into the [G 11 / Inca] Empire. He organized a personal bodyguard of Canari warriors and with these he marched north to attack the Quito tribe. The Quito were strong fighters and proved difficult for the Inca to defeat.
On the north coast of Peru, the Chimu tribe ruled an independent kingdom. They were the only large tribe remaining in the territory of today's Peru and Ecuador not conquered by the Inca. They had a very old and cultured civilization, and might have maintained their independence had they not had to defend themselves against a serious military threat from the Inca for many years.
The Inca eventually defeated the Chimu, and although some of their leaders were allowed to remain, their sons, along with the remainder of the tribe, were sent to Cuzco as hostages to learn Inca ideology and government. Finally, the coastal valleys as far south as Nazca were conquered and incorporated into the empire.
