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.
Islam and modernity
In the period between 1839 and 1876 the Ottoman government began instituting large-scale reforms as a way to modernize and strengthen the empire. Known as the Tanzimat, many of these reforms involved adopting successful European practices that were considered antithetical to conservative Muslims. In addition to military and administrative reforms, Ottoman rulers implemented reforms in the sphere of education, law, and the economy. This included new universities and changes in curricula, as well new economic systems and institutions. There were also European-inspired changes to law that restricted Islamic law to family affairs such as marriage and inheritance.
