[1] The town of San Mateo Mexicaltzingo was founded in 1475 when Axayácatl ordered a number of families be moved to the area south of what is now Toluca.

The town is well known as a producer of chicharron and serves as a distributor of food products to nearby municipalities, Toluca and even to Mexico City.

[1] Nearby are unexplored arqueological zones called de la Loma, Las Palmas, Tecacaxtitla and Bohuantilta.

The official petition to become a municipality was made by San Mateo Mexicaltzingo and its current subject communities in 1849, but such was not approved until 1869.

[1] Agriculture is the main economic activity here growing corn, animal fodder, barley, carrots, peas and other beans, plums, peaches, and apples.

The municipality covers an area of 12.2 km2 and it is located between the parallels 19° 11' 43 and 19° 13' 15 of north latitude, and the meridians 99° 33' 05 and 99° 37' 02 of west longitude.
