The Byzantine–Seljuk wars were a series of conflicts in the Middle Ages between the Byzantine Empire and the Seljuk Empire. 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. During the course of the war, the Seljuk Turks and their allies attacked the Fatimid Caliphate of Egypt, capturing Jerusalem and catalyzing the call for the First Crusade. Crusader assistance to the Byzantine Empire was mixed with treachery and looting, although substantial gains were made in the First Crusade. Within a hundred years of Manzikert, the Byzantines had successfully driven back the Seljuk Turks from the coasts of Asia Minor and extended their influence right down to Palestine and even Egypt. Later, the Byzantines were unable to extract any more assistance, and the Fourth Crusade even led to the sack of Constantinople in 1204. Before the conflict ended, the Seljuks managed to take more territory from the weakened Empire of Nicaea until the sultanate itself was taken over by the Mongols, leading to the rise of the ghazi and the conclusive Byzantine–Ottoman wars.
