Yucatán and Mayan History

From an article on History.com:

Mayans flourished and established one of their greatest cities, Chichén Itzá, in what is now Yucatán. Because it was relatively isolated from the rest of Mexico until recently, the state developed its own unique culture.

One of the most advanced indigenous cultures of the ancient Americas, the Mayans began as hunter gatherers and migrated into the Yucatán around 2500 B.C. During the pre-classic period (500 B.C.-250 A.D.) they appeared in Quintana Roo, where they established ceremonial centers at Coba, Dzibanche and Kohunlich. Quintana Roo was considered to be the gateway to the Mayan world. Between 300 and 900, the Mayans built several cities in the Yucatán region, two of the most spectacular being Chichén Itzá and Uxmal.
