Chalco

Chalco was a Nahua confederacy on Lake Chalco in the Valley of Mexico, with four sub-kingdoms each ruled by a tlatoani. In 1337 it was independent and fought repeated flower wars with the Aztecs.

In 1446 the Chalca refused stone for Huitzilopochtli's temple, prompting open war. Moctezuma I conquered Chalco around 1465 and exiled its kings to Huexotzinco; the musician Quecholcohuatl helped secure their restoration under Tizoc in 1486. After Pedro de Alvarado arrived in 1519, the Chalca joined the Spanish siege of Tenochtitlan; by 1533 Chalco was a Spanish corregimiento.
