Tziuhcoac

Tziuhcoac, also written Xiuhcohuac, was a tributary province in the Huasteca. Its territory lay east of the independent lordship of Metztitlan, between the mountains and the Gulf lowlands. Mexica campaigns under Moctezuma Ilhuicamina reached the region in the fifteenth century, and Xiuhcohuac became subject to Texcoco within the Triple Alliance. Its name has been interpreted as the place of the turquoise serpent.
