Following his father's death in 1182, Canute became sole ruler and King of Denmark in 1182. at the Urnehoved Assembly (Danish:
landsting) and subsequently at the other assemblies throughout Denmark. He immediately faced a peasant uprising in
Skåne. The peasants refused to pay Bishop
Absalon's tithe. They met at the Skåne Assembly and chose Harald Skreng, one of Canute’s friends to represent them to the king to plead their case. The king refused to hear Skreng out and began to gather an army to teach the peasants their place. Before the king could muster his army, the nobles of
Halland and
Skåne cobbled together their own army and defeated the peasants in a bloody
battle at Dösjebro (
Dysjebro) in Skåne. Canute arrived with his army and proceeded to teach the peasants a lesson with fire and sword. Canute was so relentless that Bishop Absalon begged the king to desist. Emperor
Frederick Barbarossa had compelled Canute's father to acknowledge him as overlord, and in 1184 Barbarossa sent a messenger to Canute requiring him to acknowledge the emperor as his liege. Canute failed to respond, so the emperor sent a second messenger threatening the emperor's wrath if Canute failed to acknowledge his liege lord. Bishop Absalon replied to the messenger on behalf of Canute. "Canute is as free a king as the emperor. He has as much right to Denmark as the emperor has to the Holy Roman Empire, and so the emperor should expect no allegiance from this place." . The only known copy of this insignia was discovered in
Schwerin, Germany in 1879. The king's closed crown differs from the open crowns shown on the seals of his successors. The emperor flew into a rage when he received Canute's reply, but because of troubles farther south, ordered his vassal,
Bogislaw I of
Pomerania to invade Denmark. Duke Bogislaw, recognizing a great opportunity quickly gathered 500 ships. The first notice of the pending invasion came from
Jaromar I, Prince of Rügen who sailed to Zealand to give warning. The king was in Jutland, and so it was left to Bishop Absalon to order every available ship from Zealand, Funen and Skåne to meet him in six days. Absalon sailed for Rügen with his fleet and waited for Bugislaw to show up. When the enemy failed to appear, Absalon sent out scouts to bring word when the Pomeranian fleet arrived. He ordered his men to go ashore so he could celebrate mass on Second Easter Day. In the middle of services, one of the scouts ran into the church shouting that the enemy had been sighted through the fog. "Now will I let my sword sing the mass to the praise of God!" exclaimed Absalon as he set aside the altar implements.{{cite web|url = https://runeberg.org/dbl/18/0195.html|title = Valdemar (Knudsen), 1158-1236, Biskop af Slesvig|publisher = Dansk biografisk Lexikon ==Succession==
