History
Coacalco de Berriozábal is part of the Valley of Mexico. It is located at the site of what was once the city-state of Xaltocan. Between 850 and 1521, the municipality was inhabited by Toltec people.

On 12 February 1862, General Felipe Berriozábal, then-governor of the state, signed an order that declared Coacalco an independent municipality, ending a 343-year-old dependency of Ecatepec.
