The Battle of Karbala galvanized the development of the pro-Alid[a] party (Shi’at Ali) into a unique religious sect with its own rituals and collective memory. It has a central place in the Shi’a history, tradition, and theology, and has frequently been recounted in Shi’a literature. For the Shi’a, Husayn’s suffering and martyrdom became a symbol of sacrifice in the struggle for right against wrong, and for justice and truth against injustice and falsehood. It also provides the members of the Shi’a faith with a catalog of heroic norms.
