Byzantine–Seljuk wars: Byzantine forces defeated their Seljuk opponents in the flanks of the nocturnal Battle of Kapetron, but learned of their Georgian allies' defeat in the centre the next morning.

The Byzantine–Seljuk wars were a series of conflicts in the Middle Ages between the Byzantine Empire and the Seljuk Sultanate. They shifted the balance of power in Asia Minor and Syria from the Byzantines to the Seljuk dynasty. Riding from the steppes of Central Asia, the Seljuks replicated tactics practiced by the Huns hundreds of years earlier against a similar Roman opponent but now combining it with new-found Islamic zeal. In many ways, the Seljuk resumed the conquests of the Muslims in the Byzantine–Arab Wars initiated by the Rashidun, Umayyad and Abbasid Caliphates in the Levant, North Africa and Asia Minor.

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'.

The Seljuk Empire, or the Great Seljuk Empire, was a high medieval, culturally Turco-Persian, Sunni Muslim empire, established and ruled by the Qïnïq branch of Oghuz Turks. The empire spanned a total area of 3.9 million square kilometres from Anatolia and the Levant in the west to the Hindu Kush in the east, and from Central Asia in the north to the Persian Gulf in the south, and it spanned the time period 1037–1308, though Seljuk rule beyond the Anatolian peninsula ended in 1194.

The Battle of Kapetron or Kapetrou was fought between a Byzantine-Georgian army and the Seljuq Turks at the plain of Kapetron in 1048. The event was the culmination of a major raid led by the Seljuq prince Ibrahim Inal into Byzantine-ruled Armenia. A combination of factors meant that the regular Byzantine forces were at a considerable numerical disadvantage against the Turks: the local thematic armies had been disbanded, while many of the professional troops had been diverted to the Balkans to face the revolt of Leo Tornikios. As a result, the Byzantine commanders, Aaron and Katakalon Kekaumenos, disagreed on how best to confront the invasion. Kekaumenos favoured an immediate and pre-emptive strike, while Aaron favoured a more cautious strategy until the arrival of reinforcements. Emperor Constantine IX chose the latter option and ordered his forces to adopt a passive stance, while requesting aid from the ruler of Georgian Duchy of Kldekari, Liparit IV. This allowed the Turks to ravage at will, notably leading to the sack and destruction of the great commercial centre of Artze.
