The Kings of Norway and Sweden began to send their bishops to England for consecration, and Sven Estrithson, King of Denmark, appealed to Henry and 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 evangelization. The assent of Adalbert was necessary for such a decision, which he promised to ratify only on condition that his dream of a northern patriarchate be realized. ”
