[5] Vestiges of Olmec, Chichimeca, and Tlahuica Prehispanic human settlements have been found in the area that includes modern Tetecals.

Eighty years later, the population had increased to 4,040 inhabitants that were distributed in the town of Tetecala, five haciendas, and ten ranches.

[6] One of the last battles of the Mexican War of Independence took place in Tetecala on June 2, 1821, when Pedro Ascencio Alquicira attacked royalist Dionisio Boheta.

An 1826 census reported 651 day-laborers, 50 farmers, 20 artisans, 19 merchants, two manufacturers of brandy, two presbyters, a surgeon, a teacher, and a responsible civil authority.

Commerce stands out since Tetecala had a smaller population than Xochitepec, Tlaltizapán, Puente de Ixtla, or Tlaquiltenango, but it had more commercial activity than any of them.

Lt. Manuel Arellano led the fight against the hacienda owners, who were supported by Kad Waleder, leader of the American troops who had invaded in 1847.

[6] At the outbreak of the Mexican Revolution in 1910, the owners of the haciendas of Contlalco, Cuautitla, Actopan, and Santa Cruz and wealthy merchants fled the municipality.

Atrocities were committed by both sides in the conflict, although the terrorism spread by Carranza general Pablo González Garza was without precedent.

When Jamarillo and his family were gunned down by federal police in 1962, his body was taken to the "Miguel Hidalgo Hospital" (now the House of Culture) in Tetecala for autopsy, which was performed by Dr. Ernesto González Brito.

Cascos de las Haciendas (manor houses) nearby include Santa Cruz Vista Alegre, Actopan, Cuautlita, and Cocoyotla).

[4] Local fiestas are held on February 2 (Virgen de la Candelaria) in Tetecala, May 15 (St. Isidore the Laborer) in Actopan, July 31 (St. Ignatius of Loyola) in Actopan, September 29 (St. Michael the Archangel) in Cuautitla, October 4 (San Francisco de Asís) in Tetecala, and December 12 (Virgin of Guadalupe) in the "El Paso" neighborhood.

[4] Local food includes corn or chickpea pozole with pork, chicken and even shrimp; beef jerky with cream and cheese or pork enchilada; green pip mole, red turkey mole, fish in mixiote, tamal, and clemole seasoned with wild plums and tamarind; peppers stuffed with cheese and mincemeat, and huazontles.

Cuautlita is located 6 km southeast of the Tetecala de la Reforma and includes Colonia Mariano Matamoros.
