This paper focuses on the predominant repetitive activities in which a large group engages to maintain and/or repair its identity. These repetitive activities constitute large-group rituals and can be divided into two general categories: (1) rituals that occur within a society that do not involve an active relationship with a contemporary “other” large group; and (2) rituals that occur through and depend upon the interaction with an opposing or enemy large group, usually a neighbor. Because “others” are used as reservoirs for unwanted parts, both at individual and group levels, and are needed to support aspects of identity and a shared sense of sameness, the first type of ritual may also include reference to shared images of “others” from the large group's past. They therefore may not be strictly domestic or indigenous. Furthermore, the intensity and content of both types of rituals occur across a spectrum depending on whether a large group is at peace, in a “hot” conflict with an enemy group, or otherwise destabilized due to crises.
