Alp Arslan authorized his Turkoman generals to carve their own principalities out of formerly Byzantine Anatolia, as atabegs loyal to him. Within two years the Turkmens had established control as far as the Aegean Sea under numerous beyliks: the Saltukids in Northeastern Anatolia, the Shah-Armens and the Mengujekids in Eastern Anatolia, Artuqids in Southeastern Anatolia, Danishmendis in Central Anatolia, Rum Seljuks (Beylik of Suleyman, which later moved to Central Anatolia) in Western Anatolia, and the Beylik of Tzachas of Smyrna in İzmir (Smyrna).
