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.
Iraqi Turkmen
In 2004 Scott Taylor suggested that the Iraqi Turkmen population accounted for 2,080,000 of Iraq's 25 million inhabitants (forming 8.32% of the population) whilst Patrick Clawson has stated that the Iraqi Turkmen make up about 9% of the total population. Furthermore, international organizations such as the Unrepresented Nations and Peoples Organization has stated that the Iraqi Turkmen community is 3 million or 9–13% of the Iraqi population. Iraqi Turkmen claim that their total population is over 3 million. On the other hand, some Kurdish groups claim that the Iraqi Turkmen make up 2–3% of the Iraqi population, or approximately 500,000–800,000.
