Iranian migration to Thailand began as early as the 17th century. Thai citizens of Iranian descent may be called in Thai as Khaek Ma-ngon, Khaek Mahon or Khaek Chaosen. There is a community of Thai people of Iranian descent who still practice Shia Islam in many districts throughout Bangkok, such as Yan Nawa, Bueng Kum, Saphan Sung, and Min Buri, as well as parts of Chachoengsao Province.
