State organisation of the Ottoman Empire
After the conquest of Constantinople in 1453 by Mehmed II, Ottoman sultans came to regard themselves as the successors of the Roman Empire, hence their occasional use of the titles caesar (قیصرqayser) of Rûm, and emperor, as well as the caliph of Islam. Newly enthroned Ottoman rulers were girded with the Sword of Osman, an important ceremony that served as the equivalent of European monarchs' coronation. A non-girded sultan was not eligible to have his children included in the line of succession.
