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.
January 2005 Iraqi parliamentary election
One challenge to the legitimacy of the election was the low Arab Sunni turnout, which was as low as 2% in Anbar province. Areas with mixed populations saw the vast majority of voters back Shi'ite or Kurdish parties. The largest Arab Sunni party, The Iraqis, won only 1.78% of the vote (for comparison, Arab Sunnis are thought to be 15-20% of the population).
