[1] Dzuluinicob bordered the Chetumal and Waymil provinces to the north, the Mopan and Manche Ch'ol territories to the south, and the Itza, Kowoj, and Yalain polities to the west.
[5][6] Though scarce little is known of the province's pre-Columbian history, given the aforementioned population glut, it has been suggested that Dzuluinicob emerged after a significant wave of immigration into the region.
[7][8] It has been further noted that such demographic influx may have been similar and coincident with that which gave rise to the Peten Itza Kingdom, i.e. settlement by northerly aristocratic mayors and their households upon the collapse of Mayapan and consequent disintegration of the regional council of provincial governors.
[...] Earlier writers were unaware of the existence of Dzuluinicob and attributed far more influence to the province of Chetumal than it now appears to have had.
/ Because the sole direct reference to Dzuluinicob as a provincial entity is in a unique early version of Melchor Pacheco's probanza, it would be foolhardy to venture specific claims regarding its territorial limits.
