The Constitution of the Islamic Republic of Iran mandates that the official religion of Iran is Shia Islam and the Twelver Ja'fari school, though it also mandates that other Islamic schools are to be accorded full respect, and their followers are free to act in accordance with their own jurisprudence in performing their religious rites and recognizes Zoroastrian, Jewish, and Christian Iranians as religious minorities. As part of this mandate of allowing other practices, however, the Islamic Republic does not allow Sunni mosques in areas where Sunnis are not the demographic majority.[48]
