The Ixil differ from other Mesoamerican societies in their extensive ancestor worship and their absence of a belief in animal companion spirits. The historical and archaeological evidence shows Ixil continuity with the lowland Classic Maya with comparatively little change during the Postclassic. The conclusion is tentatively drawn that the lowland Classic Maya were ancestor worshipers, and that the predominant characteristic of those Postclassic changes outside IxU country which led to the demise of Classic ceremonial centers in some areas and the later fragmentation of political units in others, derived from a basic religious change which was reflected in a change in the use of the 260-day ritual calendar. The new religion opposed ancestor worship and introduced a depersonalized soul belief system.
