 In the 16th century, the area belonged to the Santiago Tuxtla province.In 1530 there was an eruption of the San Martín Volcano, which prompted the movement of people from Ixtlán to what is now the city of San Andrés Tuxtla, then called Tuzacoalco (land between the mountains).The settlement was recognized in 1580 by the head of the Tlacotalpan, Tuztla and Cotaxtla region.
