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 Islam in Nigeria
Although the majority of the Nigerian Muslim population is Sunni, there is a significant Shia minority, particularly in the northern states of Kano and Sokoto. However, there are no actual statistics that reflect a Shia population in Nigeria, and a figure of even 5% of the total Nigerian Muslim population is thought to be too high “because of the routine conflation of Shi’a with Sunnis who express solidarity with the Iranian revolutionary program, such as those of Zakzaki’s Ikhwani.”
