The first group of Native Americans to reach the region of Chalco was "the acxotecas" coming from Tula, the famous and ancient homeland of the Toltecs, and the first town they settled was called Chalco. Later, a second group of people arrived, this were the Mihuaques. By 1160 A.D arrived teotenancas and chichimecas from the valley of Toluca, through Tláhuac. Around the lake there were other groups, including cuixocas, temimilolcas and ihuipanecas, which formed a congregation of tribes with Chalcas.
By 1354 the entire region was known by the name of Tzacualtitlán-Tenanco Amaquemeca-Chalco". For 1410 the territory of the Chalca almost a Confederate state, consisted in four domains: Acxotlan-Chalco, Tlalmanalco-Amaquemecan, Tenanco-Tepopollan and Xochimilco-Chimalhuacan, being Acxotlan-Chalco Header".
War as a means of expansion and conquest becomes common, just we mention one of many: in 1376 the "flower war" that lasts eight years and is among Mexicans and Chalco, in this war only Chalca people died in battle and is because of this long struggle for survival and defense of the territory that the Chalco region didn't achieve the splendor of Texcoco or Tenochtitlan.
There are two versions of the arrival of Hernán Cortés in the region of Chalco.
The first one is about a Chalca who says to be aware of the presence of Cortes in Tlaxcala and Cholula, await the passage of volcanoes and bring gifts of gold, the other says Chalco were to receive Cortes Texmelucan and bought her jewelry, valuable stones, bracelets, blankets, feather-rich foods among other things.

Cortés remains two days in Amecameca where you given away good food, gold and slaves.
Meanwhile, Clavijero in his book Ancient History of Mexico says that "Cortes Amecameca Ayotzingo became, instead serving as places of hot earth. Cacamac receive the Spaniards in Ayotzingo, gives them supplies and offers city Texcoco to go away. Ixtlixóchitl with Spanish helped Chalca to defend the people of Xochimilco and Tlahuac, once stayed as allies of the Spaniards, Cortes Chalca seeking protection against the constant threat of the Mexica formed so a coalition of different tribes against the Aztecs, with the defeat of the Aztecs, the Chalca again dominate their territory being committed and available to Spanish and forcing inhabitants to participate in expeditions Chalca.
The colony starts from the moment the distribution of land among the conquerors go. "Chalco, in 1533, becomes real Province for hearing decision" was of great importance as a production area of corn, wheat, barley, straw, wood, charcoal, fruits, vegetables, construction materials such as wood, volcanic rock and stone for his Piers Aytozingo and Chalco that were favored by the heavy traffic and near the city of Mexico.

"It stands out in the State of Mexico's indigenous peasant rebellion made by Julio Lopez Chavez that although it was very short (December 1867-1868), had a great importance to regional and national level, is why some authors such as Gaston Garcia Cantu, Manuel Diaz Ramirez, John Hart and others have argued that this movement was precursor of the Zapatista movement (almost 40 years earlier).
