Ottoman Caliphate
The Ottoman Caliphate (Ottoman Turkish: خلافت مقامى, romanized: hilâfet makamı, lit. 'office of the caliphate') was the claim of the heads of the Turkish Ottoman dynasty, rulers of the Ottoman Empire, to be the caliphs of Islam during the late medieval and early modern era. Ottoman rulers first assumed the style of caliph in the 14th century, though did at that point not claim religious authority beyond their own borders.
