Shia, also spelled Shiite, refers to one of the two main branches of Islam, the other being Sunni. Shia Muslims believe in the leadership of the Imams, who are seen as the rightful successors to the Prophet Muhammad, starting with Ali, Muhammad's cousin and son-in-law. This belief in a divinely appointed leadership has led to distinct religious practices and theological views that influence sectarian identities and conflicts within the Islamic world.
