Conclusion

The wars drew near to a closure when the Turks and various Mongol invaders replaced the threat of either power. From the 11th and 12th centuries onwards, the Byzantine conflicts shifted into the Byzantine-Seljuk wars with the continuing Islamic invasion of Anatolia being taken over by the Seljuk Turks.

After the defeat at the Battle of Manzikert by the Turks in 1071, the Byzantine Empire, with the help of Western Crusaders, re-established its position in the Middle East as a major power. Meanwhile, the major Arab conflicts were in the Crusades, and later against Mongolian invasions, especially that of the Ilkhanate and Timur.
