In Greece, the main religion is Greek Orthodox. Though the Greek government keeps no official religion statistics, the United Stated estimates that this branch of Christianity accounts for around 98 percent of Greek residents.
Islam is the second most common religion in Greece. One group of Muslims lives in Thrace. Accounting for around 1.3 percent of the population, this community of 150,000 enjoys official status as a Muslim minority under the 1923 Treaty of Lausanne, which ended hostilities between the Allied Powers and Turkey after World War I. According to the U.S. Department of State, it is estimated that between 500,000 and 700,000 Muslims from the Middle East, Central Asia and North Africa live in the area around Athens. Small communities of other religions, including Scientology, Roman Catholicism, Jehovah’s Witnesses and Judaism round out Greece's religious community.
