The name Azcapotzalco means "at the anthill" in Nahuatl. Its inhabitants were called Azcapotzalca.
According to chronicler Fernando Alva Ixtlilxóchitl the Tepanec's were a Chichimec group and settled in 1012 in the region west of Lake Texcoco. Its lineage begins when their Acolhua leader (or Acolnahuacatl) marries Xolotl's daughter Cuetlaxochitzin. But this information is rather in a mythical context, Acolnahuacatl's life is registered much later.
Chimalpahin places their settlement before, in 995. In fact archaeological investigations have revealed that Azcapotzalco was inhabited from the Classical period - around year 600 – and were related to the Teotihuacan’s culture and language, as it is known that they still spoke the Otomi language in the 14th century while the Nahuatl was lingua franca from 1272. Continuing with data provided by Chimalpahin, he mentions that Tepanec entered the Triple Alliance from 1047 (this Alliance is different from a much later alliance involving the Aztecs).
Azcapotzalco was founded in the 13th century in the west of Lake Texcoco. Azcapotzalco maintained a dominant hegemony with the Aztecs, who arrived in 1299, settling on the Chapultepec Hill, and were dominated.
Allowed the mexitin establishment in Chapultepec in 1281-1286 so they expelled the matlatzincas-texcaltepecas (Texcaltepec; former name of the village of Malinalco), also remained neutral when a four Nation coalition razed the Chapoltepec mexitin and Santa Catarina Sierra in 1299, when they are subjected to the Colhuacan yoke. In 1318 for the first time they attacked the Aztecs, which resulted in an increased tribute and greater participation in military campaigns.
Around of 1315, the Tepanec, Toltec and Chichimec drove the Aztecs definitively from Chapultepec. Cópil was captured and killed by the Aztecs. His heart was ripped out and thrown into the River. According to a legend, Huitzilopochtli had to kill his nephew, Cópil and threw his heart in the Lake. However, since Cópil was his relative, Huitzilopochtli decided to honor him and made a cactus grow over Cópil heart and it became a sacred place.
The Aztecs attempted to ally with the Colhua to confront the Tepanec: they were allowed to settle in Tizapán, near Colhuacan. In 1323, the Aztecs slaughtered a Colhua Princess in front of her father. The Colhua had been expelled from Tizapán and immediately declared war.
The Aztecs called for immediate Azcapotzalco protection, and from this point forward they were subject to military, economic and strategic decisions of the Tepanecas.
At Acolnahuacatl's death, his son Tezozomoc, only 23 years old, took his place; Tezozomoc may be the most important and crucial post-classical period figure. During his reign (ca. 1371-1426), Azcapotzalco reached its greatest splendor. At the time of his death in 1426, Azcapotzalco was an authentic "Hueyi Tlahtohcayotl"; it controlled trade routes at least 40 altépetl. His political decisions both destroyed villages and favored the emergence of others. He installed his sons on the thrones of many nearby altépetl, such as his son Cuacuapitzahuac who ruled Tlatelolco until 1407.
The later supremacy of Tenochtitlan was a result of Tezozómoc's policies. Tezozómoc forced the Aztecs to fight with him and together conquered the city of Colhuacan in 1385. Between 1414-1418, Azcapotzalco controlled the entire Valley of Mexico, thanks to the decisive contribution of Aztec and mercenary forces and a series of careful pacts with regional people. Azcapotzalco became an economic center of enormous power.
In 1426, When Tezozómoc died, his son Maxtla took power. Maxta failed to maintain alliances and lost the crucial support of the Aztecs by arranging for the assassination of their tlatoani Chimalpopoca. As a result, Tenochtitlan banded together with its neighbors, including Texcoco and Tlacopan, into what became known as the Triple Alliance. Together they attacked and sacked Azcapotzalco in 1428. Hegemonic power passed to Tenochtitlan and, consequently, to the Aztec Empire.

- Actually, these governors names come from two sources; in the García Granados Codex the Azcapotzalco blood line is outlined (without dates) in the following order: Maxtlacozcatl (Matlacohuatl), Chiconquiauitl, Tezcapoctli, Tehuehuactzin, Micacalcatl, Xiuhtlatonac, Acolnahuacatl y Tezozomoc; the Tlatelolco annals provide another list in which the first three and the two last names appear but misses the other three (in italics), the advantage of the second list is that these are the proposed dates in the article. The three missing names could be accommodated in an alternate sequence, considering data from other sources that placed the rise of Acolnahuacatl 1302, creating a "brief lagoon" from 1283 to 1302, even if no document suggests so.
- There are other dates in the sources, which makes him older (Ixtlilxochitl) his rise is marked in 1051 and his death in 1357, 306 years!, obviously it is mythical. Chimalpain marks a more recent and credible dates, Acolnahuacatl ruled from 1302 to 1366 and Tezozomoc 1367 to 1426. Some contemporary historians (including Lopez Austin) placed Acolnahuacatl death and Tezozómoc rise in 1371
