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.
Neo-Ottomanism
The Ottoman Empire was an influential global power which, at its peak, controlled the Balkans, most of the modern-day Middle East, most of coastal North Africa (at least nominally), and the Caucasus. Neo-Ottomanist foreign policy encourages increased engagement in these regions as part of Turkey’s growing regional influence. This foreign policy contributed to an improvement in Turkey's relations with its neighbors, particularly with Iraq, Iran and Syria. However Turkey's relations with Israel, once Turkey's ally, suffered, especially after the 2008–09 Gaza War and the 2010 Gaza flotilla raid.
