Cahal Pech was founded in the Early Middle Preclassic period and continued to thrive as a Maya city until at least the end of the Classic period, though there is ceramic evidence of a longer occupation. Recent excavations have suggested that Cahal Pech, which was most likely settled by Maya from Guatemala, is one of the earliest Maya settlements in Belize.
