The purpose of this article is to review the relations of Béla III of Hungary with the papal curia and the role Lukács, archbishop of Esztergom, played in the development of those relations. To do this, one must first direct one's attention to politics at the Byzantine court, where Manuel Comnenus succeeded to the imperial throne in 1143. Because Emperor Menuel regarded himself as heir to the territorial and intellectual integrity of old Rome and of the crown of Constantine the Great, he let it be known that he had in mind a role for the Hungarian court to play in his policies. He was the grandson of Ladislas I, the Saint of Hungary (1077–1095)—his mother, Pyrisk (Iréne) was the daughter of Ladislas—and looked. upon Hungary as an integral part of the former province(s) of (Upper and Lower) Pannonia. Emperor Manuel decided to have Béla III, educated at the imperial court.
