During the 7th and 8th centuries in Mesoamerica, there was an evident shift in the roles women played in ancient Maya society as compared with the previous two centuries. It was during this time that there was a great deal of political complexity seen both in Maya royal houses as well as in the Maya area. Warfare was a significant factor in political competition and marriage was one of the ways that alliances were made between the different polities. This was accompanied by a shift in women's roles from wife and mother to playing integral parts in courtly life, such as participating in rituals involving the supernatural world and at times ruling individual polities.
