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.
Shia Muslims in the Arab world
Unlike other sects of Islam, the Shias of Iraq have been treated horrifically under the regime of Saddam Hussein, when many Iraqi Shī‘as of Persian descent were expelled from the country in the 1980s, despite being the majority of the country at 83%. Reports indicated that no neighborhood was left intact after the 1991 uprising in Karbala. In the vicinity of the shrines of Husayn ibn Ali and Abbas ibn Ali, most of the buildings surrounding the shrines were completely reduced to rubble. The shrines themselves were scarred from bullet marks and tank fire. They were, however, quickly restored by Shiite Donations.
