George of Kiev
George was an Eastern Orthodox Metropolitan of Kiev and all Rus', serving from 1069 to 1073.
George was the seventh Byzantine church leader in Kievan Rus, and he arrived to what is now Ukraine around 1062. Because George would not recognize the sanctity of the local martyrs, four years after his appointment he returned to Byzantium.
Metropolitan George is the author of polemical work "Struggle with the Latin Church" in relation to the 1054 East–West Schism.
