Pechenegs, a Turkic tribe, entered Byzantine territory in 944 as auxiliary troops of Prince Igor of Kiev. For a time, they maintained contact with Byzantium as mercenaries of the Rus. Later, relations between the Pechenegs and the Rus princes worsened. Pechenegs then began to raid Byzantine lands on their own. Since the 1030s, the Cumans had become active near the Don River. Their pressure forced the Pechenegs to move into Byzantine lands in the Balkans. As a nomadic people, Pechenegs lived by raiding and plundering. Their advance into the Balkans made Byzantine territories a direct target. They even carried out threatening actions near Constantinople. The Byzantine emperors had to develop new policies to defend the empire. This article aims to examine the Byzantine-Pecheneg conflicts in the Balkans from military and political perspectives based on primary sources from the period, with a particular focus on demonstrating the strategic importance of the Balkans for the Byzantine Empire during the reign of Alexius Comnenus.
