Archaeologists estimate that at their peak, 1 to 2 million Mayans lived within the borders of present day Belize.
Mighty Maya cities such as Caracol, Xunantunich and Lamanai dotted the landscape, with small agricultural communities farming the land between. The Maya civilization is divided into the Pre-Classic (1000 BC to AD 300), the Classic (AD 300 to 900) when the civilization reached its height of development, and the Post-Classic (AD 1000 to 1500) when the civilization fell apart and disappeared.
No one knows for certain what caused the disappearance of the Maya. Perhaps it was war, loss of faith, famine, or a series of natural disasters.
