Seljuk Sultanate in the context of "Byzantine–Seljuk wars"

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 Battle of Manzikert of 1071 is widely regarded as the turning point against the Byzantines in their war against the Seljuks. The battle opened up Anatolia for further Turkish migrations and settlements. The Byzantine military was of questionable quality before 1071 with regular Turkish incursions overrunning the failing theme system. Even after Manzikert, Byzantine rule over Asia Minor did not end immediately, nor were any heavy concessions levied by the Turks on their opponents – it took another 20 years before the Turks were in control of the entire Anatolian peninsula and not for long either.
