[5] For himself Christopher used the otherwise unknown title of arch king (archirex), because in his opinion he ruled an empire, not simply three different countries, and thus ranked immediately under the European emperor.

North Jutland, especially Vendsyssel, was so restive that a peasant army of 25,000 led by Henrik Tagesen Reventlow (executed 1441) posed a serious threat to Christopher's continued reign.

Before the king could act, Jutland's noble families raised their own army and marched west of Aalborg to meet Reventlow's forces.

[7] The peasants had created a gigantic wagon fortress three layers deep to protect themselves from the mounted knights they knew would come against them.

They also placed tree branches across the bog in front of the camp and then cast earth on top to make it look like solid ground.

The overconfident army of nobles led by Eske Jensen Brock appeared at St Jorgen's Hill (St. Jørgensbjerg) on 3 May 1441.

With his own army Christopher rode north to the rebel camp at Husby Hole near St Jorgen's Hill in northern Jutland.

[12] The Swedish nobles were not happy to relinquish any power and thus didn't like him, claiming he was too German for them and that he allowed his uncle (ex-King Erik) to plunder shipping from his castle on Gotland without any attempt to stop him.

He carried on an ineffective policy of war and negotiations against Erik in Gotland which did little to help the dissatisfaction within both Sweden and the Hanseatic League.

The results of this policy of balance were still not reached when he suddenly died as the last descendant of Valdemar IV of Denmark.
