32nd federal electoral district of the State of Mexico

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 (Distrito Federal) and is part of the Mexico City metropolitan area. The city and municipality lie on the old lakebed of Lake Chalco, which was drained like much of the Basin of Mexico. The city name comes from the nearby Xico hill (Cerro de Xico) and the name of the municipality comes from the old lake plus a reference to the "Programa Nacional de Solidaridad" (National Program of Solidarity) which was initiated here. The municipality's glyph and shield make reference to both names. It is a distinct entity from the city and municipality of Chalco, which is nearby. "Chalco" in both names refers to the Chalca tribe that were one of the original inhabitants of the area.

Valle de Chalco, officially named Valle de Chalco Solidaridad, is a municipality located in the State of Mexico, Mexico, on the eastern outskirts of the metropolitan area of Mexico City. Formerly part of the municipality of Chalco, it was split off as a separate entity in 1994, during the presidency of Salinas de Gortari, under his Programa Nacional de Solidaridad (National Solidarity Program). The municipality lies on the old bed of Lake Chalco, which was substantially drained in the nineteenth century. Technically, the municipal seat is Xico, after a high point of land that once formed an island, and now remains as a small hill within an otherwise monotonous, urban expanse. "Chalco" refers to the Chalca tribe, whose territory covered the area around the lake, prior to the Spanish conquest of the Aztec Empire. As of 2006, Chalco included part of the world's largest mega-slum, along with Ciudad Nezahualcoyotl and Ixtapaluca.

Tlapacoya is an important archaeological site in Mexico, located at the foot of the Tlapacoya volcano, southeast of Mexico City, on the former shore of Lake Chalco. Tlapacoya was a major site for the Tlatilco culture. Tlapacoya is known in particular for Tlapacoya figurines. These sophisticated earthware figurines were generally created between 1500 and 300 BCE and are representative of the Preclassic Period. Tlapacoya was also a manufacturing center for so-called "Dragon Pots" (see photo below). These flat-bottomed cylindrical bowls have white or buff surfaces incised with almost abstract Olmec-style drawings, generally of were-jaguars.

Chālco [ˈt͡ʃaːɬko] was a complex pre-Columbian Nahua altepetl or confederacy in central Mexico. It was divided into the four sub-altepetl of Tlalmanalco/Tlacochcalco, Amaquemecan, Tenanco Texopalco Tepopolla and Chimalhuacan-Chalco, which were themselves further subdivided into altepetl tlayacatl, each with its own tlatoani (king). Its inhabitants were known as the Chālcatl [ˈt͡ʃaːɬkat͡ɬ] (singular) or Chālcah [ˈt͡ʃaːɬkaʔ] (plural). In the 14th and early 15th centuries, flower wars were fought between the Chalca and the Aztecs. Serious war erupted in 1446. According to the Amaqueme historian Chimalpahin, this was because the Chalca refused a Mexica demand to contribute building materials for the temple of Huitzilopochtli. Chalco was finally conquered by the Aztecs under Moctezuma I in or around 1465, and the kings of Chalco were exiled to Huexotzinco. The rulerships were restored by Tizoc in 1486, who installed new tlatoque. This was achieved, in part, by the diplomacy work carried out by the Chalcan musician Quecholcohuatl when he performed a politically-driven composition for Axayacatl in 1479. This story was recorded by Chimalpahin in the seventh of his Eight Relations (see The liberation of Chalco). Chalco paid more tribute to Tenochtitlan in the form of food than any other region in the Valley of Mexico, probably because of its fertile soil and location.The Spanish conquistadors Pedro de Alvarado and Bernardino Vázquez de Tapia reached Chalco in the fall of 1519. The Chalca allied with the Spaniards and participated in the defeat of the Aztecs.: 320  Hernán Cortés claimed Chalco for himself as an encomienda, but failed to maintain his possession of it. Chalco was designated a corregimiento by 1533. Several places outside the traditional region of Chalco were added to it in colonial times.

Chalco de Díaz Covarrubias (Nahuatl pronunciation: [ˈt͡ʃaːɬko]) is a city that is municipal seat of the surrounding municipality of Chalco. It lies in the eastern part of the State of Mexico just east of the Federal District of Mexico and is considered part of the Mexico City metropolitan area. Chalco name is Nahuatl, and comes from Challi: "lake edge", and Co: "place" therefore both words together mean "on the edge of the lake".The municipal head, bears the surname of Diaz Covarrubias, in honor of Juan Díaz Covarrubias, one of the practitioners of medicine who was heroically shot in Tacubaya in 1859.

Lake Zumpango (Spanish: Laguna de Zumpango; Nahuatl languages: Tzompanco, lit. 'string of scalps') is an endorheic basin located in the Valley of Mexico in the municipality of Zumpango and adjacent to the municipality of Teoloyucan. Tzompanco was formerly the northernmost of five interconnected lakes, covering about 1,500 square kilometers (580 sq mi) (the other lakes being Lake Xaltocan, Lake Xochimilco, Lake Chalco and Lake Texcoco). The Valley of Mexico was a centre for several pre-Columbian civilizations including Teotihuacan, the Toltec, and the Aztec Empire. 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.

Lake Chalco was an endorheic lake formerly located in the Valley of Mexico, and was important for Mesoamerican cultural development in central Mexico. The lake was named after the ancient city of Chalco on its former eastern shore. Lake Chalco and Lake Xochimilco were the original habitat of the axolotl, an amphibian that is critically endangered due to urban destruction.

The Nest (Spanish: El Nido) is an aviary located in Ixtapaluca, state of Mexico. Founded by veterinarian Jesús López Estudillo in the 1960s, it is a civil association created to preserve over 300 different species of birds, both Mexican and the rest of South America, Africa and Asia, mostly endangered. The association—formerly known as Wildlife (Spanish: Vida Silvestre)—also has a space for breeding and conservation of the most endangered species. The Nest is the most diverse aviary in the world and the third largest in Latin America. The logo is the quetzal, as Jesús López Estudillo was the first to achieve captive breeding of the bird, which had been a traditional symbol of freedom, characterized by not being able to survive outside its native habitat.
