The province had entered under the reign of Turkish civilizations following the 1071 Malazgirt (Manzikert) Battle; Seljuk and Anatolian States for years and than Ottoman Empire after the 1515 Caldiran Battle. The town of Malazgirt is an important and famous name in Turkish history being the site of the battle of Malazgirt which led the first Turks setting their foot in Anatolia. At that time Manzikert was an important trading post of the ancient Kingdom of Armenia. Here in 1071 the Byzantine emperor Romanus IV fought against Sultan Alp Arslan of the Seljuk Turks. Although Alp Arslan tried to come to a peace agreement before the battle and despite the fact that Romanus was depending heavily on unreliable Norman mercenaries, the emperor refused to negotiate. After this inevitable battle, Alp Arslan defeated the Byzantines and captured Romanus. This victory opened the doors of Anatolia to the Turks, and this date is considered to be the beginning of the Turks and that of Islam in Anatolia. It’s also following this date that the Turks fully conquered the whole of Anatolia and established the Anatolian Seljuk state.
