Following Manzikert, the civil war in Byzantium and the failure of the Roman Empire to retake Anatolia, the first Turkish beyliks emerge in Anatolia.  In the anarchy caused by the collapse of the Roman military apparatus, bands of Turks begin making alliances with the settled elites of Anatolia, offering them protection for a price.   Soon the Turks are invited into the cities of Anatolia, replacing the now-vanished Roman military to become the lords of new principalities - beyliks.  In the east of Anatolia, numerous beyliks emerge - the Mengucekids, the Danishmands, the Saltukids and the Artukids.  But in the West, on the very doorstep of Constantinople, another political entity is born as the sons of Kutalmish, and in particular his son Sulayman, dive deep into Byzantine politics.  Through canny political maneuvering, Sulayman founds the next great Turkish state - the Sultanate of Rum.
