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.
Ottoman Empire
The word "Ottoman" is a historical anglicisation of the name of Osman I, the founder of the Empire and of the ruling House of Osman (also known as the Ottoman dynasty). Osman's name in turn was the Turkish form of the Arabic name "ʿUthmān" (). In Ottoman Turkish, the empire was referred to as "Devlet-i ʿAlīye-yi ʿOsmānīye" (), (literally "The Supreme Ottoman State") or alternatively "ʿOsmānlı Devleti" (). In Modern Turkish, it is known as "Osmanlı İmparatorluğu" ("The Ottoman Empire") or "Osmanlı Devleti" ("The Ottoman State").
