Constantine VIII
During the Easter celebration in 1028, Henry received regality from the hands of his father with consent of the princes and was vested with the duchies of Bavaria and Swabia. Conrad temporarily had evolved plans to marry his son with Zoe Porphyrogenita, a daughter of the Byzantine Emperor Constantine VIII. Nevertheless, after these ambitions had failed, Gunhilda and Henry were finally betrothed at Pentecost 1035 in Bamberg and married one year later in Nijmegen. Upon her wedding, she took the German name "Kunigunde".
