Battle of Manzikert
With the commencement of the Turkish rule in Anatolia after the Battle of Manzikert (Malazgirt) (1071 A.C.), the region became a part of the Seljuk Empire in 1084 A.C. But the Seljuk rule was frequently interrupted by the Crusades which had a devastating influence on both Byzantine and Seljuk territories in Asia Minor.
