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 Yemen
Religion in Yemen primarily consists of two principal religious groups of Islam; Sunni and Shi'a. About 65% of the Muslim population is Sunni, and 30% is Shi'a. Sunnis are primarily Shafi'i, but also include significant groups of Malikis and Hanbalis. Shi'as are primarily Zaidis, though they also have significant minorities of Twelver Shi'as and Musta'ali Western Isma'ili Shi'as (see: Shi'a Islam in Yemen).
The Sunnis are predominantly in the south and southeast. The Zaidis are predominantly in the north and northwest, while the Jafaris and Isma'ilis are mostly located in the main centers of Sana'a and Ma'rib. There are mixed communities in the larger cities.
