Sabean-Mandaeans are confined to lower Iraq, except for minuscule communities in Khorramshahr and Ahwaz, in southwestern Iran, and a community of silversmiths and their families in Baghdad. They are primarily located in the Marshes or on the two rivers, at al-Amara, Qal’at-Salih, Nasiriya, Suq al-Shuyukh and Qurna. The size of the community is estimated at less than 5,000 in Iraq.
The religion is a form of Gnosticism, descended from ancient Mesopotamian worship, with rituals that resemble those of Zoroastrian and Nestorian worship. John the Baptist is its central prophet, and they practise immersion in flowing water, symbolic of the creative life force, as an act of ritual purity. Nevertheless, scholars believe that the Sabean-Mandaean religion pre-dates Baptism. Sabean-Mandaean faith bars the use of violence or the carrying of weapons. Adherents have dhimmi status as ‘People of the Book’, mentioned in the Qur’an, although this is disputed.
The Sabean-Mandaeans should not be confused either with the ‘Sabians’ of Harran, a pagan sect which deliberately adopted the name Sabian in order to avoid Muslim persecution, or with the Sabaeans, the inhabitants of ancient Sheba, in south Yemen.
