Calakmul

Calakmul is a Maya archaeological site in the Mexican state of Campeche, 35 kilometres from the Guatemalan border, and was one of the largest and most powerful Maya cities. It was the seat of the Kaan dynasty, the Kingdom of the Snake, whose emblem glyph is more widely distributed than that of any other Maya city; at its Late Classic height the city had an estimated 50,000 people. Throughout the Classic period it was a rival of Tikal, and under Yuknoom Che'en II, crowned in 636, it held a wide network of vassals. Its alliances collapsed after Tikal defeated El Peru in 743 and Naranjo in 744, and the city was finally abandoned after the early 10th century.
