These people were conquered a number of times, including by the Olmecs, the Nahuatlacs and by the region of Tlacopan before being conquered by the Aztec Triple Alliance and then, of course, the Spaniards.

When Maxtla laid siege to Tenochtitlan in 1428, Chimalpopoca's successor and uncle, Itzcoatl, repelled his forces with the aid of an alliance of city states, including Texcoco under Nezahualcoyotl and many former Tepanec allies, notably Tlacopan.
