Cnut the Great
There is some doubt as to when Roskilde became the seat of the Bishop of Roskilde. When Sweyn Forkbeard conquered England in 1013, he began sending English bishops to Denmark, a process which was continued by his successor Cnut the Great. This caused some conflict with the Archbishop of Hamburg, who regarded Scandinavia as belonging to the Archdiocese of Bremen. The earliest known bishop of Roskilde was Gerbrand, who had been a cleric with Cnut the Great, and who was intercepted by the Archbishop of Hamburg-Bremen's men when he sailed to Denmark in 1022. Only after swearing allegiance to the archbishop was he allowed to continue his journey. The archbishop may have had good reason to be suspicious, as documents of the time suggest that Cnut the Great may have planned to create an archdiocese in Roskilde, with Gerbrand as archbishop.
