In 1045, the Byzantine Empire conquered Bagratid Armenia. Soon, the other Armenian states fell under Byzantine control as well. The Byzantine rule was short lived, as in 1071 Seljuk Turks defeated the Byzantines and conquered Armenia at the Battle of Manzikert, establishing the Seljuk Empire. To escape death or servitude at the hands of those who had assassinated his relative, Gagik II, King of Ani, an Armenian named Roupen, went with some of his countrymen into the gorges of the Taurus Mountains and then into Tarsus of Cilicia. The Byzantine governor of the palace gave them shelter where the Armenian Kingdom of Cilicia was eventually established on 6 January 1198 under King Leo I, a descendant of Prince Roupen.
Output:
Who vanquished Bagratid Armenia?
