Acolhuacan or Aculhuacan (Nahuatl: ācōlhuahcān;[2] pronounced [aːkoːlˈwaʔkaːn]) was a pre-Columbian province in the east of the Valley of Mexico, inhabited by the Acolhua. Its capital was initially Coatlichan,[3] but this settlement was eventually eclipsed in importance by Texcoco (Tetzcoco).[4]
In some sources, the name "Acolhuacan" was also used to refer to a city within the larger Acolhuacan province (e.g., in the Codex Mendoza, folio 21v).[5] Frances Berdan and Patricia Rieff Anawalt argue that it was likely Texcoco, Acolman, or Coatlichan, with the latter two being "the most likely prospects."[1] Additional scholars largely agree that Acolhuacan was likely another name for Coatlichan.[6][7]
