Tláhuac became a delegation of Mexico City only in 1929. In that year, a presidential decree listed seven original towns that constituted the territory.
The delegation, is today an alcaldía, and later added a few more neighborhoods and sections. These seven towns constitute the oldest and most vibrant part of Tláhuac.
The seven Tláhuac pueblos originarios are said to have begun in 1222. A group of Chichimeca people settled in a town that became Cuitláhuac, today's San Pedro Tláhuac. In the listings below, you'll see that many of the towns have histories going back even further, to prehistorical times.
In 1446, the emperor Moctezuma Ilhuicamina of Tenochtitlan, began construction of the Calzada de Tláhuac connecting to Tulyehualco (in today's Xochimilco) and dividing Lake Chalco from the Xochimilco Lake. This was a defining moment for the peoples on either side of the water dividing the two lakes.
Visits to any and all of them are richly rewarded with new perspectives, deeper historical understandings, and always, with fresh and nutritious food.
