The town of Ixtlahuaca de Rayón
The city of Ixtlahuca de Rayón had a population of 7,114 at the 2005 census. When the town was officially established, the appendage of "de Rayón" was added to the name in honor of Francisco López Rayón who was executed by royalist forces during the Mexican War of Independence here on the side of the municipal palace. The original Mazahua town was located about 4 miles east of the current city. The population center was moved in 1545 when it was decided that the area needed a parish church of its own (it had been dependent on the parish of Tlalchichilpan prior), and the priest decided upon the location, finishing construction in 1552. Viceroy Luis de Velasco designated the area as a town. Ixtlahuaca gained city status in 1992.

The area was originally called J'apui, which comes from the Mazahua language, as a number of Mazahua tribes came to settle the land near the Xocotépetl volcano. The area was conquered by Moctezuma II just before the arrival of the Spanish. The Mazahuas, along with other tribes that inhabited the areas west and north of Tenochtitlan (now Mexico City) submitted to Spanish domination without a fight and their lands were distributed among Hernán Cortés's soldiers.
