The Alawites, also known as Nusayrites, are an Arab ethnoreligious group that live primarily in the Levant and follow Alawism, a sect of Islam that originated from Shia Islam. The Alawites venerate Ali ibn Abi Talib, revered as the first Imam in the Twelver school, as the physical manifestation of God. The group is believed to have been founded by Ibn Nusayr during the 9th century. Ibn Nusayr was a disciple of the tenth Twelver Imam, Ali al-Hadi and of the eleventh Twelver Imam, Hasan al-Askari. For this reason, Alawites are also called Nusayris.
