The Aztecs were a Mesoamerican culture that flourished in central Mexico in the post-classic period from 1300 to 1521. The Aztec people included different ethnic groups of central Mexico, particularly those groups who spoke the Nahuatl language and who dominated large parts of Mesoamerica from the 14th to the 16th centuries. Aztec culture was organized into city-states (altepetl), some of which joined to form alliances, political confederations, or empires. The Aztec Empire was a confederation of three city-states established in 1427: Tenochtitlan, city-state of the Mexica or Tenochca; Texcoco; and Tlacopan, previously part of the Tepanec empire, whose dominant power was Azcapotzalco. Although the term Aztecs is often narrowly restricted to the Mexica of Tenochtitlan, it is also broadly used to refer to Nahua polities or peoples of central Mexico in the prehispanic era, as well as the Spanish colonial era (1521–1821). The definitions of Aztec and Aztecs have long been the topic of scholarly discussion ever since German scientist Alexander von Humboldt established its common usage in the early 19th century.

Xico is a city in the State of Mexico, Mexico. It serves as the municipal seat of Valle de Chalco municipality, with which it is, for all practical purposes, coterminous. The municipality lies adjacent to the east side of the Federal District and is part of the Mexico City metropolitan area.

"Chalco" in both names refers to the Chalca tribe that were one of the original inhabitants of the area.

When the Spaniards arrived in the Valley of Mexico, it had one of the highest population concentrations in the world with about one million people. After the conquest of the Aztec Empire, the Spaniards rebuilt the largest and most dominant city, Mēxihco Tenōchtitlan, renaming it Ciudad de México and over time began to drain the lakes' waters to control flooding.

Pueblo Culhuacán is an officially designated neighborhood of the Iztapalapa borough of Mexico City, which used to be a major pre-Hispanic city. Ancient Culhuacán was founded around 600 CE and the site has been continuously occupied since. The city was conquered by the Aztecs in the 15th century, but the Aztecs considered the city to have status with early rulers marrying into Culhua nobility to legitimize themselves. After the Spanish conquest of the Aztec Empire, the Franciscans and later the Augustinians made Culhuacán a major evangelization center, with the latter building the monastery complex which remains to this day. Today, Culhucan is fully integrated into Mexico City physically and politically. This area was designated as a "Barrio Mágico" by the city in 2011.

After the conquest of the Aztec Empire, the Spaniards began to drain the lakes' waters to control flooding. Over the centuries Lake Zumpango lost it its inflows and outflows and became polluted by sewage and garbage dumps. However, in recent years, the lagoon is becoming cleaner again.
