A slave was the lowest rank in the Mayan society. They had the "honor" to sacrifice themselves to the god. You could be born int o slavery or become a slave if you dint pay your taxes. Most slaves helped their owners with labor depending on the masters job. Some slave had an easier life than peasants.
Since peasant had to work all day in the harvest season. Peasant had it easier depending on their owners. They weren't treated so poorly they dint have all rights but hey did have some like they could go to royal weeding. Although they were in the lowest rank they din't have the worst life.
