Baptized by Byzantium in 865, Bulgarians adopted the Byzantine Christian tradition known as Eastern Orthodoxy. Muslims constitute the second most significant religious community, thanks to the spread, in the fourteenth century, of Islam during the Ottoman conquest of the Balkans. At the end of World War II, 85 % of Bulgarian citizens were Orthodox and 13 % were Muslim. Tiny congregations of Catholics, Protestants, Jews, etc. also exist. Even though they were suppressed under communism, these religious denominations very quickly returned to the public square once the Iron Curtain had fallen, a tendency which was also stimulated by the 1991 Constitution, which proclaimed full-scale religious freedom.
