The Gulf: Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, United Arab Emirates (UAE), Yemen

Syriac Christianity was present in the Gulf from the 4th to the 9th centuries, faded under Islam, and then re-entered the region through colonial ventures and foreign missionaries. These Muslim-majority countries all grant Christians freedom of worship (with the exception of Saudi Arabia), but at present there is no significant indigenous Christianity community. UAE, Qatar, Kuwait, and Bahrain claim the four top spots in the world for highest ratio of expatriates to local populations, and nearly all Christians in the Gulf are economic migrants. This has resulted in a great diversity of ethnic and denominational diversity among Christians. As of 2015, the percentage of the population identifying as Christian is 13% in Bahrain, 13% in UAE, 10% in Kuwait, 9% in Qatar, 5% in Saudi Arabia, 4% in Oman, and 0.1% in Yemen. The Bible Society in the Gulf (BSG), founded in 1999, is an ecumenical mission-oriented organization in the region.
