The Lombard Revolt in Bari was marked by the Greek citizens' uprising against Melus, a prominent Lombard leader. The city of Bari had become a strategic point within the Byzantine-controlled territory in Italy, which was threatened by Lombard raids. Historically, the Lombards had established territories in Italy, often clashing with Byzantine forces and local populations. The Greek inhabitants of Bari, primarily loyal to the Byzantine Empire, saw the Lombard presence as an existential threat to their way of life and governance. As discontent towards the Lombard rule grew, the Greek citizens banded together on November 6, 1011, challenging Melus and his followers in a concerted attempt to reclaim autonomy and stability in their city.

Faced with the aggression of the Lombard rebels, the Greek citizens demonstrated remarkable unity and determination. They fought fiercely, leveraging their knowledge of the local terrain and employing tactical advantages. Their efforts culminated in a successful confrontation that led to the overthrow of Melus's forces. Subsequently, the citizens delivered Bari back into the hands of Basil Mesardonites, the Byzantine governor or catepan of the region. This victory not only secured Bari for the Byzantine Empire but also reinvigorated the status of the Byzantine rule in southern Italy, strengthening the empire's foothold against external threats.

The uprising in Bari showcased the enduring influence of the Byzantine Empire in Italy, demonstrating how local populations could assert themselves against foreign dominance. Furthermore, it illustrated the complexities of Byzantine interactions with various cultural groups in the region, highlighting a moment of resistance that emphasized local identities amid broader imperial politics.
