Around 1000 BC, the Olmecs were joined in Northern Mexico by the warlike Huastec people. However, they were defeated by the Aztecs, and later by the Spanish. They left behind only a few circular temples and palaces. The Zapotecs established themselves about 1000 BC. They made the Olmec city of Monte Alban, the capital.
After 1000AD, they were driven off by the Mixtecs to the Mitla area. Tilantongo in Southern Mexico was their capital. They displaced the Zapotecs, and erected pyramids and magnificent tombs. They were conquered by the Spanish in the 16th century. Between 720 AD and 1150 AD, the Toltecs ruled Central Mexico. Their priest-king Quetzlcoatl led his people to Mixtec and Mayan regions, but he was driven away. Later, the Aztecs worshipped him as chief god and founder hero.
