Religion in Europe Religion in Europe has been a major influence on today's society art, culture, philosophy and law. The largest religion in Europe is Christianity.[2] Three countries in Southeastern Europe have Muslim majorities. Ancient European religions included veneration for deities such as Zeus. Modern revival movements of these religions include Heathenism, Rodnovery, Romuva, Druidry, Wicca, and others. Smaller religions include Indian religions, Judaism, and some East Asian religions, which are found in their largest groups in Britain, France, and Kalmykia.
Religion in ancient Rome In 380, under Theodosius I, Nicene Christianity became the official state religion of the Roman Empire. Christian heretics as well as non-Christians were subject to exclusion from public life or persecution, though Rome's original religious hierarchy and many aspects of its ritual influenced Christian forms,[206] and many pre-Christian beliefs and practices survived in Christian festivals and local traditions.
