Byzantine Empire/Armanya

The Byzantine Empire, also known as the Eastern Roman Empire, East Roman Empire and Byzantium, is the continuation of the Roman Empire in its eastern provinces during Late Antiquity and the Middle Ages, when its capital was Constatninople. It survived the fragmentation of the Western Roman Empire for an additional thousand of years and survived the Ottoman siege of Constantinople, but its territory now solely composed of Constantinople. The Byzantine Empire borders Greek to the west and the Ottoman Empire to the east.
Byzantium's position as an independent state on the Greek side makes it a neutral major trading hub for the Ottoman Empire and Greece, but it also serves as a quasi-client state of the Ottomans and a de facto protected state under Novaya, which is known for arming, funding, equipping and training the Byzantine Peacekeeping Security Force, composed solely of Novayan soldiers who finished serving in the Novayan Armed Forces for four years.
