Petén Basin
geographical region of Mesoamerica
The Petén Basin is a geographical subregion of the Maya Lowlands, primarily located in northern Guatemala within the Department of El Petén, and into the state of Campeche in southeastern Mexico.
During the Late Preclassic and Classic periods of pre-Columbian Mesoamerican chronology many major centers of the Maya civilization flourished, such as Tikal and Calakmul. A distinctive Petén-style of Maya architecture and inscriptions arose. The archaeological sites La Sufricaya and Holmul are also located in this region.
History
By the first half of the 1st millennium BCE, the Petén and Mirador Basin of this region were already well-established with a number of monumental sites and cities of the Maya civilization. Significant Maya sites of this Preclassic era of Mesoamerican chronology include Nakbé, El Mirador, Naachtun, San Bartolo and Cival in the Mirador Basin.
Classic Period
Later, Petén became the heartland of the Maya Classic Period (c. 200 – 900 CE). At its height around 750 it is estimated that the Petén Basin was home to several million people, being one of the most densely populated regions of the world at the time. Some areas are estimated to have had ca 2,000 people/km2.
