Before the 13th century, both Nahua and Purépecha peoples were here, sustaining themselves by agriculture and fishing. The Purépecha are descendants of a late arrival of Chichimecas who came from the north. At Lake Patzcuaro, they came upon people with similar cultures to their own but who were more technically and socially advanced. The formation of the Purépecha state began in the 13th century, when these people started their own dominion at Uayameo, today Santa Fe de la Laguna and becoming dominant over the entire Lake Patzcuaro area by the 15th century. Conquest of neighboring tribes and territories occurred between 1401 and 1450, absorbing peoples with different cultures and languages into the empire. By the late 15th century, this state rivaled that of the Aztecs, expanding their territory over much of what is now Michoacán and into part of Colima, Nayarit, Querétaro, Guanajuato, Guerrero and Jalisco. The Aztecs attempted to invade Purépecha but were repelled. This would later cause the Purépecha to deny the Aztecs aid in the defense of Tenochtitlan against the Spanish. The Michoacán history has been studied from archaeological evidence and historical documents, such as the literary work "Relación de Michoacán", written in 1524 by Frair Jeronimo de Alcalá. Hence it is known that the first settlers of the region were several Chichimeca tribes which arrived in different times, and therefore evolved differently.

According to another version the Huandacareo word, is of Chichimeca origin and translates as "Preaching Place", as it derives from the "huandaca" word that means "speech". Chichimec culture Chichimeca was the name that the Nahua peoples of Mexico generically applied to a wide range of semi-nomadic peoples who inhabited the north of modern-day Mexico and southwestern United States, and carried the same sense as the European term "barbarian". The name was adopted with a pejorative tone by the Spaniards when referring especially to the semi-nomadic hunter-gatherer peoples of northern Mexico. In modern times only one ethnic group is customarily referred to as Chichimecs, namely the Chichimeca Jonaz, although lately this usage is being changed for simply
