Even though Oman is a modern country, western influences are quite restricted. The Ibadi form of Islam is also conservative like Sunni Islam and Shi'a Islam. About 75% of Oman is Muslim. As is the case with most Middle Eastern countries, alcohol is only available in some hotels and few restaurants.
The religion of Oman is Islam, but Oman is a special case being the only country in the world where neither Sunni nor Shi'i dominates, rather the smaller branch of Ibadism.
Politics of Oman takes place in a framework of an absolute monarchy whereby the Sultan of Oman is not only head of state, but also the head of government.
