Anatolian Principalities (beyliks)

Anatolian beyliks (Turkish: Anadolu beylikleri, Ottoman Turkish: Tavâif-i mülûk, Beylik Turkish pronunciation: [bejlic]) were small principalities (or petty kingdoms) in Anatolia governed by Beys, the first of which were founded at the end of the 11th century. A second more extensive period of foundations took place as a result of the decline of the Seljuq Sultanate of Rûm in the second half of the 13th century.

One of the beyliks, that of the Osmanoğlu from the Kayi tribe of the Oghuz Turks, from its capital in Bursa completed its conquest of other beyliks by the late 15th century, becoming the Ottoman Empire.
