Christianity in Iran dates back to the early years of the religion during the time of Jesus. 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 historical 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. Iranian Christians have played a significant part in the historical Christian mission: currently, there are at least 600 churches and 300,000[1]–370,000 converts.[1]
