Chiismo is a branch of Shia Islam that emphasizes the leadership of the Imams, who are considered the rightful successors to the Prophet Muhammad. Followers believe that these Imams possess special spiritual and temporal authority, guiding the community in religious and moral matters. The term "chiismo" is often used in the context of the historical and theological differences between Shia and Sunni Muslims. Chiismo has a rich tradition of scholarship, rituals, and community practices, which play a significant role in the lives of its adherents, particularly during important events like Ashura.
