Danish Civil Wars

Civil war in Denmark from 1146 until 1157

The Danish Civil Wars were a series of civil wars fought in the Kingdom of Denmark, first from 1131 to 1134 over the murder of Canute Lavard, then from 1139 to 1143, and finally a war of succession fought from 1146 to 1157, after the abdication of Eric III of Denmark, the first monarch in Danish history to have abdicated. The first phase of the war was fought between King Eric II of Denmark and King Niels joined by Magnus the Strong. The second phase of the war was fought between the son of Magnus the Strong, Canute V of Denmark, the son of Eric II of Denmark, Sweyn III of Denmark, and his cousin Valdemar I of Denmark, son of Canute Lavard. The civil wars marked an increase in the influence of the Holy Roman Empire in Denmark, and for a time after, Denmark was a vassal state of Emperor Frederick I. The war ended with the deaths of seven kings. Two of the kings, Olaf Haraldsen and Magnus the Strong, are not amongst the official Danish line of kings. The other kings are Niels I, Eric II, Eric III, Canute V and Sweyn III.
