Iran's indigenous Christians include an estimated 250,000 Armenians, some 32,000 Assyrians, and a small number of Roman Catholic, Anglican, and Protestant Iranians converted by missionaries in the nineteenth and twentieth centuries. The Armenians are predominantly urban and are concentrated in Tehran and Esfahan ออออ smaller communities exist in Tabriz, Arak, and other cities. A majority of the Assyrians are also urban, although there are still several Assyrian villages in the Lake Urmia region. Armenians and Assyrians were recognized as official religious minorities under the 1906 constitution. Although Armenians and Assyrians have encountered individual prejudice, they have not been subjected to persecution. During the twentieth century, Christians in general have participated in the economic and social life of Tehran. The Armenians, especially, achieved a relatively high standard of living and maintained a large number of parochial primary and secondary schools.

The new, republican Constitution of 1979 also recognized the Armenians and Assyrians as official religious minorities (see Constitutional Framework , ch. 4). They are entitled to elect their own representatives to the Majlis and are permitted to follow their own religious laws in matters of marriage, divorce, and inheritance. Other Christians have not received any special recognition, and there have been a number of incidents of persecution of Iranian Anglicans. All Christians are required to observe the new laws relating to attire, prohibition of alcohol, and segregation by sex at public gatherings. Christians have resented these laws because they have infringed on their traditional religious practices. In addition, the administration of the Armenian schools has been a source of tension between Christians and the government. The Ministry of Education has insisted that the principals of such schools be Muslims, that all religion courses be taught in Persian, that any Armenian literature classes have government approval, and that all female students observe hejab inside the schools.
