The Battle of Manzikert was fought between the Byzantine Empire and the Seljuk Empire on 26 August 1071 near Manzikert, theme of Iberia (modern Malazgirt in Muş Province, Turkey). The decisive defeat of the Byzantine army and the capture of the Emperor Romanos IV Diogenes played an important role in undermining Byzantine authority in Anatolia and Armenia, and allowed for the gradual Turkification of Anatolia. Many of the Turks, who had been travelling westward during the 11th century, saw the victory at Manzikert as an entrance to Asia Minor.
