Texcoco de Mora is a city located in the State of Mexico, 25 km northeast of Mexico City. Texcoco de Mora is the municipal seat of the municipality of Texcoco. In the pre-Hispanic era, this was a major Aztec city on the shores of Lake Texcoco. After the Conquest, the city was initially the second most important after Mexico City, but its importance faded over time, becoming more rural in character. Over the colonial and post-independence periods, most of Lake Texcoco was drained and the city is no longer on the shore and much of the municipality is on lakebed. Numerous Aztec archeological finds have been discovered here, including the 125 tonne stone statue of Tlaloc, which now resides at the Museum of Anthropology in Mexico City.
Much of Texcoco's recent history involves the clash of the populace with local, state and federal authorities. The most serious of these is the continued attempts to develop an airport here, which despite the saturation of the current Mexico City airport, is opposed by local residents. The city and municipality is home to a number of archeological sites, such as the palace of Nezahualcoyotl, Texcotzingo and Huexotla.
