Note: The Kingdom of Serbs, Croats and Slovenes (1918-1929) was later renamed the Kingdom of Yugoslavia (1929-1941). As could be expected, the amalgamation of these states created a religiously pluralistic society. The legally recognized religions were the Catholic, Lutheran and Reformed Churches, the Orthodox Church, Islam and the Greek Orthodox Church. In May 1941, a new law was passed rendering it easier to change religion. People could fill in a form and simply submit it to the authorities, which then issued a certificate of religion.
