Alawism (Arabic: علوية, romanized: ʿAlawiyya), also known as Nusayrism (Arabic: نصيرية, romanized: Nuṣayriyya), is an offshoot of early Shia Islam with influences from ancient Iranian, Christian, and Gnostic traditions. Its adherents, called the Alawites, are estimated to number around 4 million and are primarily concentrated in the Levant. Alawites venerate Ali ibn Abi Talib, the "first imam" in the Twelver school, as a manifestation of the divine essence.
Alawite beliefs are centered in a divine Trinity, comprising three aspects of the one God, the ma'na (meaning), the ism (name), and the bab (door). These emanations are understood to have undergone reincarnation cyclically seven times in human form throughout history, the last seventh incarnation being that of Ali, Muhammad and Salman the Persian. Alawite practices include consecration of wine in the form of Mass, entombing the deceased in sarcophagi, observing cultural holidays such as Akitu, Christmas, Nowruz, Mawlid and Gazwela.
