Cause

The Pechenegs had settled in the former Byzantine province of Paradounabon in what is now northern Bulgaria. After rejecting Pecheneg peace overtures, Emperor Alexios I Komnenos led his army from Constantinople, crossed the Balkan Mountains, and besieged the provincial capital of Dorostolon, seeking to reassert Byzantine control over the region.

Event

Byzantine forces took the city of Dorostolon after a brief siege, but the citadels held out. Fearing the approach of the main Pecheneg army, Alexios began withdrawing, only to be caught and brought to battle. After hard fighting with heavy casualties on both sides, the arrival of Pecheneg reinforcements triggered a panic among the Byzantines. Alexios personally tried to rally his troops but discipline collapsed, and the army fled.

Consequence

The Pecheneg victory at Dorostolon exposed the Byzantine Empire's Balkan provinces to sustained raiding. Although the Cumans soon attacked the Pechenegs from the rear, both sides waged further campaigns over several years. The conflict was ultimately resolved only by the decisive Byzantine victory at the Battle of Levounion in 1091, which eliminated the Pecheneg threat to the Empire.
