Following the 1071 Seljuq victory over the Byzantine Empire at the Battle of Manzikert and the subsequent conquest of Anatolia, Oghuz clans began settling in present-day Turkey. The Seljuq Sultanate's central power established in Konya was largely the result of using these clans under Beys called "uç bey" or "uj begi" especially in border areas to ensure safety against the Byzantines; "uç" is a Turkish term for a border territory equivalent to marches, thus "uç beyi" is similar to margrave in Europe. These clans, led by beys, would receive military and financial aid from the Seljuqs in return for their services and full allegiance.
