The Ottoman Empire, which spanned from the 13th to the early 20th century, was one of history's most religiously diverse states. At its height, it encompassed Muslims, Orthodox Christians, Catholics, Jews, Armenians, and numerous other faith communities.
Islam as the State Religion
Islam served as the official religion, and the Sultan held the dual role of political ruler and, after 1517, Caliph — the spiritual leader of Sunni Muslims worldwide.
The Millet System
The millet system allowed non-Muslim communities to govern themselves according to their own laws in matters of personal status, family affairs, education, and religious practice. Major millets included the Greek Orthodox, Armenian, and Jewish communities.
Religious Tolerance
Non-Muslims paid the jizya tax in exchange for protection and autonomy. The empire became a refuge for persecuted minorities, including Sephardic Jews expelled from Spain in 1492.
Legacy
The millet system's influence can still be felt in the legal systems of Turkey, Greece, Israel, and Lebanon, where religious communities retain jurisdiction over personal status matters.
