At the end of the thirteenth century, with the Seljuk Sultanate of Rum in terminal decline, Anatolia was divided into several small independent Turkish principalities, called beyliks. One of these beyliks, bordering the Orthodox Christian Byzantine Empire, was led by Osman I. Osman's tiny state would gradually expand over the next two hundred years to become one of the world's great empires, known to posterity as the Ottoman (Osmanli) Empire, after their first leader.

About the base game:

Field of Glory II Medieval is a turn-based tactical game set in the High Middle Ages from 1040 AD to 1270 AD. This was the heyday of the mounted knight. Armoured from head to toe by the later 12th century, European knights rode heavy horses in tight formation, and delivered a devastating charge with couched lances. Lead your chosen army and its named generals to victory in set-piece historical battles or "what-if" custom battle situations against an AI or human opponent. Choose your forces from historically accurate orders of battle allowing all of the options and variations that would be available to a real general of that nation at any date during the era.
