San Andrés Hueyapan is a small town in the rural northeastern part of the Mexican state of Morelos, formerly in the municipality of Tetela del Volcán.
It lies at an elevation of ca 2000–2500 metres above sea level on the southern slopes of the active volcano Popocatépetl.
To the west of Hueyapan runs the Amatzinac river, to the north is the Popocatépetl-Iztaccíhuatl natural reserve, and to the south the town of Tlacotepec and to the east is the municipality of Tochimilco which belongs to the state of Puebla located in the midlands.
The people of Hueyapan mostly practice subsistence agriculture: They produce maize, beans, squash, peach, avocado and plums.
The thread is made on traditional spindles called malacates, dyed with natural dyes (such as Añil, Walnut husks, St John's wort) and the fabric is woven on backstrap looms.
[citation needed] According to Durán in 1524, Hueyapan was founded by people from Xochimilco around 902 CE, conquered by the Aztecs under Moctezuma II and in 1521, during the Spanish conquest of the Aztec Empire, it fell to the Gonzalo de Sandoval, assisted by female Conquistador María Estrada.
[citation needed] In colonial times Hueyapan was part of the encomienda originally given to the Estrada family, but was later laid directly under the Spanish throne.
[citation needed] When Morelos became a state in 1869, Hueyapan was part of the municipality of Ocuituco, and then passed to Tetela del Volcan in 1937.
Police and dissidents battled in Cuernavaca, and councillor Lilia González Cortés was kidnapped and beaten in an attempt to get her to resign.
