In 1081, Sulayman reigns in İznik as the Sultan of Rum.  But his sultanate is aspirational - really, he is a mere border lord.  A bey among beys.  And so Sulayman begins to lay the foundations for the Sultanate of Rum, expanding his power across Western Anatolia.  Burning with ambition and desire to reclaim the birthright of the line of Kutalmish, Sulayman then invades Antioch and even Aleppo.  And the very audacity that allowed him to found the Sultanate of Rum destroys him.
