The Byzantine–Seljuk wars were a series of decisive battles that shifted the balance of power in Asia Minor and Syria from the Byzantine Empire to the Seljuks. 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 Abassid Caliphates in the Levant, North Africa and Asia Minor.
