The Yarsan or Ahl-e Haqq (Kurdish: یارسان‎, Yarsan, Persian: اهل حق‎‎ Ahl-e Haqq "People of Truth"), is a syncretic religion founded by Sultan Sahak in the late 14th century in western Iran. The total number of members is estimated at around 500,000 or 1,000,000, primarily found in western Iran and eastern Iraq, mostly ethnic Goran Kurds, though there are also smaller groups of Persian, Lori, Azeri and Arab adherents. Some Yarsanis in Iraq are called Kaka'i.
