Byzantine general Belisarius completes the conquest of Sicily, defeating the Gothic garrison of Palermo (Panormos), and ending his consulship for the year.

The Byzantine Empire, also known as the Eastern Roman Empire, was the continuation of the Roman Empire centred on Constantinople during late antiquity and the Middle Ages. Having survived the events that caused the fall of the Western Roman Empire in the 5th century AD, it endured until the fall of Constantinople to the Ottoman Empire in 1453. The term 'Byzantine Empire' was coined only after its demise; its citizens used the term 'Roman Empire' and called themselves 'Romans'.

Belisarius was a military commander of the Byzantine Empire under Emperor Justinian I. Belisarius was instrumental in the reconquest of much of the Mediterranean territory belonging to the former Western Roman Empire, which had been lost less than a century prior. He is considered one of the greatest military commanders of Byzantium and in history generally.

Sicily, officially the Sicilian Region, is an island in the central Mediterranean Sea and one of the 20 regions of Italy, situated south of the Italian Peninsula in continental Europe. With 4.7 million inhabitants, including 1.2 million in and around the capital city of Palermo, it is both the largest and most populous island in the Mediterranean Sea.

The Ostrogoths were a Roman-era Germanic people. In the 5th century, they followed the Visigoths in creating one of the two great Gothic kingdoms within the Western Roman Empire, drawing upon the large Gothic populations who had settled in the Balkans in the 4th century. While the Visigoths had formed under the leadership of Alaric I, the new Ostrogothic political entity which came to rule Italy was formed in the Balkans under Theodoric the Great.
