Sweyn II of Denmark
Adalbert worked to increase the influence of his archbishopric, and thereby also the influence of the Holy Roman Empire, but encountered competition in Scandinavia from missionary bishops despatched from England and elsewhere who sometimes found greater favour from rulers and ordinary lay people alike. King Sweyn II of Denmark appealed to the Emperor and to Pope Leo IX for an archbishop of his own, which would mean a loss to Hamburg of lands just yielding fruits after two hundred years of Christianization. The whole discussion was cut short by the death of both Pope (1054) and Emperor (1056).
