The Purépecha Empire, also known as the Kingdom of Tzintzuntzan, was a polity in pre-Columbian Mexico. Its territory roughly covered the geographic area of the present-day Mexican state of Michoacán, as well as eastern Jalisco, southern Guanajuato, and western Guerrero. At the time of the Spanish conquest, it was the second-largest state in Mesoamerica. The state is also colloquially known as the Tarascan Empire.
