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 the Seljuk Empire 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 of Armenia, King of Ani, an Armenian named Ruben I, Prince of Armenia, 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 Leo I, King of Armenia, a descendant of Prince Ruben.
