It is a settlement that due to its geographical position maintained a long occupational continuity. The first material evidence corresponds to the late Preclassic (300 - 50 BC), when it would have had links with settlements in northern Belize and southern Quintana Roo, a relationship that is broken towards the late Classic, when it strengthens its relationship with the interior of the Yucatan Peninsula and has a significant population growth, which is related to the construction of some of the buildings that are preserved today. By the Early Classic period (250 - 600 A.D.), Muyil was already an important city in which important Petén-style buildings were constructed, such as El Castillo and the three basements of the Entrance Group. Due to its strategic location, towards the early Postclassic (1000 - 1200 A.D.), it maintained some contacts, first with Chichén Itzá, and later with Mayapán. In the late Postclassic (1200 - 1450 A.D.), most of the known buildings were built, and when the city gained great importance by inserting itself into the coastal trade networks of the Peninsula.
