Bagrat IV of Georgia (born 1018)

Bagrat IV, of the Bagrationi dynasty, was the king (mepe) of the Kingdom of Georgia from 1027 to 1072. During his long and eventful reign, Bagrat sought to repress the great nobility and to secure Georgia's sovereignty from the Byzantine and Seljuk Empires. In a series of intermingled conflicts, Bagrat succeeded in defeating his most powerful vassals and rivals of the Liparitid family, bringing several feudal enclaves under his control and reducing the kings of Lori and Kakheti-Hereti, as well as the emir of Tbilisi to vassalage. Like many medieval Caucasian rulers, he bore several Byzantine titles, particularly those of Nobilissimus, Kouropalates, and sebastos.
