Cuauhnahuac
Cuauhnahuac was the principal town of the Tlahuica, a Nahua people in the warm valley of Morelos. In 1337 it was an independent kingdom in western Morelos.
Seeking its cotton, Huitzilihuitl of Tenochtitlan went to war after being refused a marriage alliance. He won in 1396 and married the princess who bore Moctezuma I. Nezahualcoyotl crushed a rebellion under Miquiuix in 1433. In 1521 Gonzalo de Sandoval and Cortés stormed and burned the city; Cortés built a palace in the valley in 1526.
