Research in Guanajuato realize a bajio society inhabited by important examples, are known as culture or tradition Chupícuaro funeral and archaeological evidence of what has been called by Beatriz Braniff like Morales phase, after Chupícuaro seated in the side of the River Laja. Possibly this contemporary and historical context, Peralta represents the continuation of an original cultural development inside Bajio, emanating from regional change processes and characterized by its monumental architecture.

At the Peralta´s age (between 300 to 650 AD), Teotihuacan (Mexico) and Monte Alban (Oaxaca) were in full swing, had a social and political organization Stratus or state with well-defined social classes, a high level of specialization in work and producing for the market. In the Bajio societies had a system of socio-political organization than they were at least 6 regions in the political, social networks shared, kinship and the same system of beliefs and ritual practices. Economically, the company relied on a system of regional production and exchange.

Monumental architecture of Peralta is one of the highest expressions of the population constructive lived in the Bajio 1,500 years ago. These human groups fed agriculture practiced in terraces on the slopes of the hills and very probably took Rio Lerma (river) rising moisture for crops in some parts of the plain. Ethnic affiliation of this population is unknown, references found in colonial documents are limited to the immediate past so we expect genetic studies are finding the remains to establish the relationships among population abajeña and subsequently , compared with other archaeological cases and current populations, whether Nahuas or Otomies.
