Вальдемар I
In 1157, the three agreed to divide Denmark in three between themselves. Sweyn III hosted a great banquet for Canute V, Absalon, and Valdemar I, during which he planned to kill all three. Canute V was killed, but Absalon and Valdemar I escaped. Valdemar I at this point returned to Jutland. Sweyn III quickly launched an invasion there, but only to be defeated by Valdemar I in the Battle of Grathe Heath on 23 October 1157. Consequently, Sweyn III was killed during a fight, allegedly by a group of peasants who stumbled upon him as he was fleeing from the battlefield. In total, the Danish civil war had by then lasted over ten years. Valdemar I, now having outlived all his rival pretenders, became the sole King of Denmark.
