when did the teotihuacan civilization start and end
Teotihuacan The city is thought to have been established around 100 BC, with major monuments continuously under construction until about 250 AD.[2] The city may have lasted until sometime between the 7th and 8th centuries AD, but its major monuments were sacked and systematically burned around 550 AD.
Navajo Archaeological and historical evidence suggests the Athabaskan ancestors of the Navajos and Apaches entered the Southwest around 1400 CE.[7][8] The Navajo oral tradition is said to retain references of this migration.[citation needed]
