“Today, there are at least 600 churches for 250,000 Christians in Iran. A number of Christian denominations are represented in Iran. Many members of the larger, older churches belong to minority ethnic groups – the Assyrians and Armenians – having their own distinctive culture and language…In 1976, the Christian population numbered 168,593 people, mostly Armenians. Due to the Iran-Iraq war in the 1980s and the dissolution of the Soviet Union in the 1990s, almost half of the Armenians migrated to the newly independent Republic of Armenia. However, the opposite trend has occurred since 2000, and the number of Christians with Iranian citizenship increased to 109,415 in 2006. At the same time, significant immigration of Assyrians from Iraq has been recorded due to massacres and harassment in post-Saddam Iraq.”
