Christianity in Iran

In Iran, Christianity dates back to the early years of the religion. Through this time the Christian faith has always been followed by a minority of the population of Iran under its different state religions: Zoroastrianism in ancient Persia, followed by Sunni Islam in the Middle Ages after the Arab conquest, then Shia Islam since the Safavid conversion of the 15th century. However, Christians comprised a larger share of the population in the past than they do today. Armenians are the largest Christian community in Iran.
