MOQUIHUIX (mo-kee-wiss'), king of Tlaltelolco, born about 1420; died in Mexico in 1470. Tlaltelolco was a small city in the suburbs of Mexico, and was governed for 110 years by a branch of the imperial family of the Aztecs. Under the reign of Montezuma I., Moquihuix served with distinction, and greatly contributed to the victories and conquests of the Aztec emperor, who rewarded him with the hand of his cousin, the sister of Axayacatl. After the death of Montezuma and the accession of Axayacatl, Moquihuix organized a league between the dissatisfied Mexican caciques, but, on the eve of receiving strong re-enforcements and declaring open rebellion, his wife gave information of his plans to her brother. The latter immediately collected all his forces, and marching against Moquihuix defeated him and besieged Tlaltelolco, which, after several weeks, was taken by storm. Moquihuix was sacrificed upon the altar of the god Mexitli by Axayacatl, who opened his victim's breast and offered his heart to the divinity. After defeating also the partisans of Moquihuix, the emperor annexed their territory, and Tlaltelolco never regained its independence.
