Yazidism is a syncretic, monotheistic religion practiced by the Yazidis, an ethnoreligious group which resides primarily in northern Iraq, northern Syria, and southeastern Turkey. Yazidism is considered by its adherents to be the oldest religion in the world and the first truly monotheistic faith. The Yazidi calendar states that the religion, as well as the universe, is almost 7,000 years old, which is 5,000 years older than the Gregorian Calendar and 1,000 years older than the Jewish calendar. Yazidism has had a rich history of syncretic development. For thousands of years, Yazidism incorporated elements of Zoroastrianism, Manichaeism, Gnosticism, Christianity, and Islam, all of which coalesced from 1162 CE to the 15th century CE. Ultimately, this process created Yazidi culture and ethnic identity. However, to understand Yazidism, its history must first be explained.
