United States Department of State, Report on Human Rights Practices in Iran - 1999 (2000)
“ The Government restricts freedom of religion. The Constitution declares that the "official religion of Iran is Islam and the sect followed is that of Ja'fari (Twelver) Shi'ism," and that this principle is "eternally immutable." It also states that "other Islamic denominations are to be accorded full respect," and recognizes Zoroastrians, Christians, and Jews (Iran's pre-Islamic religions) as the only "protected religious minorities." Religions not specifically protected under the Constitution do not enjoy freedom of religion. ”
