Islam in the Ottoman Empire
Islam was the official religion of the Ottoman Empire. The highest position in Islam, "caliphate", was claimed by the sultan, after the defeat of the Mamluks which was established as Ottoman Caliphate. The Sultan was to be a devout Muslim and was given the literal authority of the Caliph. Additionally, Sunni clerics had tremendous influence over government and their authority was central to the regulation of the economy. Despite all this, the Sultan also had a right to decree, enforcing a code called Kanun (law) in Turkish. Additionally, there was a supreme clerical position called the Sheykhulislam ("Sheykh of Islam" in Arabic). Minorities, particularly Christians and Jews but also some others, were mandated to pay the jizya, the poll tax as mandated by traditional Islam.
Millet (Ottoman Empire)
In the Ottoman Empire, a millet was a separate court of law pertaining to "personal law" under which a confessional community (a group abiding by the laws of Muslim Sharia, Christian Canon law, or Jewish Halakha) was allowed to rule itself under its own laws. Despite frequently being referred to as a "system", before the nineteenth century the organization of what are now retrospectively called millets in the Ottoman Empire was far from systematic. Rather, non-Muslims were simply given a significant degree of autonomy within their own community, without an overarching structure for the 'millet' as a whole. The notion of distinct millets corresponding to different religious communities within the empire would not emerge until the eighteenth century. Subsequently, the existence of the millet system was justified through numerous foundation myths linking it back to the time of Sultan Mehmed the Conqueror (r. 1451-81), although it is now understood that no such system existed in the fifteenth century. After the Ottoman Tanzimat (1839–76) reforms, the term was used for legally protected religious minority groups, similar to the way other countries use the word "nation". The word "millet" comes from the Arabic word "millah" (ملة) and literally means "nation". The millet system has been called an example of pre-modern religious pluralism.
