Byzantium defeats the Pechenegs at Levounion
On 29 April 1091 (Julian calendar) the Byzantine emperor Alexios I Komnenos and his Cuman allies fell on the camp of the Pechenegs at Levounion, near the River Maritsa in Thrace. The nomadic Pechenegs had raided deep into the empire for years and had come with their families, and the battle became a slaughter. It ended the Pecheneg threat to Byzantium for a generation. The victory was the first great success of Alexios’s long effort to restore the empire.
