The Mixtecs (ˈmiːstɛks,_ˈmiːʃtɛks), or Mixtecos, are indigenous Mesoamerican peoples of Mexico inhabiting the region known as La Mixteca of Oaxaca and Puebla as well as La Montaña Region and Costa Chica Regions of the state of Guerrero. The Mixtec culture was the main Mixtec civilization, which lasted from around 1500 BC until being conquered by the Spanish in 1523.
The Mixtec region is generally divided into three subregions based on geography: the Mixteca Alta (Upper Mixtec or Ñuu Savi Sukun), the Mixteca Baja (Lower Mixtec or Ñuu I'ni), and the Mixteca Costa (Coastal Mixtec or Ñuu Andivi). The Alta is drier with higher elevations, while the Baja is lower in elevation, hot but dry, and the Coasta also low in elevation but much more humid and tropical. The Alta has seen the most study by archaeologists, with evidence for human settlement going back to the Archaic and Early Formative periods. The first urbanized sites emerged here. Long considered to be part of the larger Mixteca region, groups living in the Baja were probably more culturally related to neighboring peoples in Eastern Guerrero than they were to the Mixtecs of the Alta. They even had their own hieroglyphic writing system called ñuiñe. The Costa only came under control of the Mixtecs during the military campaigns of the Mixtec cultural hero Eight Deer Jaguar Claw. Originally from Tilantongo in the Alta, Eight Deer and his armies conquered several major and minor kingdoms on their way to the coast, establishing the capital of Tututepec in the Lower Río Verde valley. Previously, the Costa had been primarily occupied by the Chatinos.
In pre-Columbian times, a number of Mixtec kingdoms competed and allied with each other and with Zapotec kingdoms in the Central Valleys. Like the rest of the indigenous peoples of Mexico, the Mixtec were conquered by the Spanish invaders and their indigenous allies in the 16th century. Pre-Columbian Mixtecs numbered around 1.5 million. Today there are approximately 800,000 Mixtec people in Mexico, and there are also large populations in the United States.
