The modern day state of Hidalgo is located within the pre-Hispanic region of Mesoamerica. Numerous migrations of indigenous people took place through here, mostly arriving or passing through from the north, with many eventually settling in the Valley of Mexico. The Toltecs initially settled in Xochicoatlán, now the municipality of Molango at the beginning of the 7th century. From here they dispersed to locales such as Huejutla and Tollatzingo (now called Tulancingo) where they eventually had their capital of Tollan, today known as Tula.
