Tetela del Volcán or simply Tetela, is a town and municipality in the Mexican state of Morelos. It is located on the slopes of the volcano Popocatépetl. 18°57′48″N 99°15′12″W / 18.96333°N 99.25333°W. The city serves as the municipal seat for the surrounding municipality of the same name. It is notable for its sixteenth century Dominican ex-convent which together with a number of other early monasteries nearby in the area has been declared a UNESCO World Heritage Site. The municipality reported 16,428 inhabitants in the year 2000 census. Other towns in the municipality of Tetela del Volcán include Hueyapan, Xochicalco (not to be confused with the archeological site of the same name) and Tlamimilulpan.
The toponym Tetela comes from Nahuatl and means "place of rocks". The Volcán ("volcano") referred to is, of course, Popocatépetl.
In 1503, Tetela del Volcán and nearby Hueyapan were subjugated to the Aztec Empire by Moctezuma II. The first Spaniards to arrive in Tetela were Bernardino Vázquez de Tapia and Pedro de Alvarado in 1519. After the fall of Tenochtitlán Cortés arrived in Tetela del Volcán, where he found the Indians to be resistant and fierce. According to Diego Durán their subjugation was achieved only thanks to the intervention of María Estrada and her husband Pedro Sánchez Farfán, for which Cortés awarded the couple the lands of Tetela as an encomienda. In 1561 this encomienda was revoked and laid under the Spanish Crown directly, and in the Relacion Geográfica from 1665 this "realengo" appears to be administrated by corregidor Cristóbal Martínez de Maldonado.
