Axocopan

Axocopan, known as Ajacuba, lies in the southern Mezquital Valley of central Mexico. Its Nahuatl name refers to bitter or sour water. The settlement belonged to a region inhabited by Otomí communities and drawn into the expanding power of central Mexican rulers. In the fifteenth century the Mexica brought Axocopan into their northern provinces, extending their authority beyond the Basin of Mexico toward the dry valleys of the north.
