Battle of Antioch on the Meander

The Battle of Antioch on the Meander was a military engagement near Antioch-on-the-Meander between the forces of the Empire of Nicaea and the Seljuk Sultanate of Rûm. The Turkish defeat ensured continued Nicaean hegemony of the Aegean coast of Asia Minor. The Seljuk sultan, Kaykhusraw I, was killed on the field of battle. The battle took place near the modern town of Yamalak in Kuyucak district in Aydın Province.

Following the capture of Constantinople by the forces of the Fourth Crusade and the partition of the Byzantine Empire, Theodore Laskaris , crowned emperor in 1208, built up a power base in the former Byzantine territory of western Anatolia. This new polity was to become known as the Empire of Nicaea. Nicaea was one of the main Greek successor states that claimed the heritage of the Byzantine Empire, the other successor states were Epirus and later the Empire of Thessalonica in western Greece. Nicaea was threatened from the north by the new Latin Empire established by the Crusaders, and from the east by the Seljuk Sultanate of Rum.
