The site was first settled between 600 and 300 BC, in the latter portion of the Middle Preclassic period, when it most likely was a fairly small site. This Maya city then had a long and continuous occupational history until the Early Postclassic, up to around AD 1250, with peaks in the Late Preclassic and Late Classic periods. Motul de San José had begun to refer to Tikal as its overlord in the late 4th century AD; by the 7th century it had switched its allegiance to Calakmul, Tikal's great rival, before returning its allegiance to Tikal in the early 8th century. In the late 8th century Motul de San José appears to have been conquered by Dos Pilas, capital of the Petexbatún kingdom.
