Riyasat (Serbo-Croatian: rijaset ријасет; Bulgarian: старшинство) is a main executive body of the Islamic communities in the Balkan region.
[1] During the Ottoman Empire, all Muslims were subjected to the shaykh al-Islām, the supreme religious authority, even though the sultan maintained the title of kaliph.
The conflict reached its peak when the Ottoman Sublime Porte named Ahmed Şükrü, a former Rumelian kazasker, a new Bosnian-Herzegovinian mufti on 18 June 1880.
On 17 October 1882, emperor Franz Joseph issued an imperial decree in which he proclaimed Hadžiomerović a reis-ul-ulema (grand mufti) of Bosnia and Herzegovina.
After Hadžiomerović was named grand mufti, the institution of Riyasat, as main executive body of the Islamic community in Bosnia and Herzegovina, was established.
