Iranian- Armenian or sometimes called Persian- Armenian are Iranian citizens of Armenian origin. Their number is about 100,000. They mostly live in Tehran and Jolfa district. The Armenian-Iranians were very influential and active in the modernization of Iran during the 19th and 20th centuries. After the Iranian Revolution, many Armenians immigrated to Armenian diasporic communities in North America and Western Europe.Today the Armenians are Iran's largest Christian religious minority in Iran. Despite their cultural Armenian identity in Iran, no sizeable numbers of Armenian-Iranians hold Armenian citizenship.
