Identity elements
Shield
It is formed by a red triangle, fragmented in the center of each of its sides and with rounded corners, which represents the conjunction of the municipalities of Cuautitlán, Tepotzotlán and Tultitlán; Inside the triangle, a white circle stands out with ramifications towards each of the sides that form it. Forming a single image, a letter «C», in green, and a letter «I», in black, appear integrated.
Glyph
The glyph is formed by a tree with a tooth open in the center of the trunk, and means "abundance between the heads". The spindles or malacates with the cotton are the glyph that represented the goddess Tlazolteotl, protector of the weavers, and Izcalli is represented by the glyph calli, "house".
In the period of the independence war, in order to control by the Spanish the participation of the "rebels" in the war, a proclamation was issued to the sub-delegate of Cuautitlán, offering the grace of pardon to all those who belonged to its jurisdiction and who participated in the movement. Already promulgated, in 1827, the Political Constitution of the Free and Sovereign State of Mexico, the Departmental Board decreed on December 23, 1837, that the department of Mexico be divided into 13 districts, of which the fourth was Cuautitlán.
In 1855, nine districts and 33 districts were delimited, and the fifth was named Tlalnepantla, made up of that locality, Cuautitlán, Tlalpan and Zumpango. The history and strategic location gave rise to the original towns of the municipality: Axotlán, San Juan Atlamica, La Aurora, Santa Bárbara Tlacatecpan, San José Huilango, San Lorenzo Riotenco, San Mateo Ixtacalco, San Martín Tepetlixpan, Santa María Tianguistengo, San Francisco Tepojaco, Santiago Tepalcapa, El Rosario, and San Sebastián Xhala.
To keep the workers close to the various factories that flourished in the city, especially in the town of La Aurora, 225 adobe or tepetate houses were built around the facilities known as rancherías. They had services such as: drinking water, drainage, bathrooms, a tienda de raya () called "La Vizcaya", a school (they were provided with supplies such as notebooks, pencils, books), streets and passenger cars for their transportation. La Vizcaya was the first factory that existed in this direction of Cuautitlán and that shipped products by rail.
In 1965, Gonzalo Monroy Ortega, then municipal president of Cuautitlán, asked the local legislature to make the colony of La Aurora disappear to become part of the town of La Aurora, but this request was not answered positively, because the two towns are only separated by a canal. On April 1, 1961, La Vizcaya closed due to the competition that arose at that time with the production of products derived from petroleum, which reduced the sale and distribution of coastals of natural fibers. Originally, Cuautitlán Izcalli was planned to be the first self-sufficient city in the metropolitan area of the Valley of Mexico, and for this, a large part of the territory of existing municipalities was taken, such as Cuautitlán, Tepotzotlán, Tultitlán and Atizapán de Zaragoza. Like many other projects of the time, one of the objectives of building this city was the regulation of population growth and the reduction of congestion in the metropolitan area. The city was created using the plans of European and American cities as a base,
Decree Number 71 of the H. XLV Legislature of the State of Mexico, signed on June 22, 1973, stipulates that the official name of municipality number 121 of the State of Mexico is Cuautitlán Izcalli:
