Religion in Iraq
Islam is the official state religion in the Republic of Iraq, but the constitution guarantees freedom of religion. Iraq is a multi ethnic and multi religious country with Islam, Christianity, Yazdanism, Zoroastrianism, Shabakism, Judaism, Mandaeism, Bahā'i, Ahl-e Haqq-Yarsanis, Ishikism and numerous other religions all having a presence in the country. Shia Islam is the main religion in Iraq followed by 60–65% of the population, while Sunni Islam is followed by 32–37% of the people. Many cities throughout Iraq have been areas of historical prominence for both Shia and Sunni Muslims, including Najaf, Karbala, Baghdad and Samarra.
Culture of Iran
Today of the 98% of Muslims living in Iran, around 89% are Shi'a and only around 9% are Sunni.This is quite the opposite trend of the percentage distribution of Shi'a to Sunni Islam followers in the rest of the Muslim population from state to state (primarily in the Middle East) and throughout the rest of the world. This data is from the government of Iran and most likely contains false information. It is very likely that the percentage of Muslims living in Iran is highly exaggerated as Islam is forced under the Islamic Republic's sharia law.
