Citizens of the Islamic Republic of Iran are officially divided into four categories: Muslims, Zoroastrians, Jews and Christians. This official division ignores other religious minorities in Iran, notably those of the Baháʼí Faith. State sanctioned persecution of Bahá’ís follows from them being an "non-recognized" religious minority without any legal existence, classified as "unprotected infidels" by the authorities, and are subject to systematic discrimination on the basis of their beliefs.
