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.
Humanitarian crises of the Iraq War
Although Christians represent less than 5% of the total Iraqi population, they make up 40% of the refugees now living in nearby countries, according to U.N. High Commissioner for Refugees. UNHCR estimates that Christians comprise 24% of Iraqis currently seeking asylum in Syria. The census in 1987 counted 1.4 million Christians, however since the 2003 invasion radicalized Iraqi culture, the total number of Christians dropped to about 500,000, half of which live in Baghdad.
