What came beforeAI-assisted

The Seljuk Sultanate of Rum had been expanding into Anatolia since the late 11th century, gradually eroding Byzantine territorial control. By the early 13th century, the Byzantines had lost most of inland Anatolia and held only coastal regions and the Balkans.

Sinope, on the Black Sea coast, remained one of the last major Byzantine-held ports in northern Anatolia. The city was strategically vital for trade and naval operations in the region.

Who was involvedAI-assisted

The Seljuk Sultanate of Rum, led by Kaykhusraw I, conducted the military campaign to capture Sinope. The Byzantine Empire, weakened after the Fourth Crusade (1204), was unable to mount an effective defense.
