CAMINATZIN (cah-me-naht-zeen'), also called Cacamatzin, Cacamazin, Cacumatzin, and Ca-cumazin, Mexican king, died in 1521. He was nephew of Montezuma, reigned over Tezcoco, the principal City of Anahuac, and made an official visit to Cortes at Ayotzinco. When Caminatzin suggested a declaration of war against the foreigners, the proposal was received with enthusiasm, and he called upon the Spaniards to leave the country immediately. Cortes was preparing to march against Tezcoco. when the representations of Montezuma concerning the defenses of the town and the daring of the population induced him to change his plan and resort to treason. At his instigation Montezuma invited his nephew to Mexico to become reconciled with the Spaniards. Caminatzin answered that he could enter Mexico only to destroy the oppressors of his country. Montezuma then dispatched secret agents to Tezcoco to get possession of the young prince. His officers and friends were corrupted, and he was delivered by them to Cortes, imprisoned, and subsequently replaced on the throne by his brother Cuicuitzcatzin. He was released after the expulsion of the Spaniards from the City of Mexico, and is supposed to have perished soon after in the siege.
