After the death of Canute Lavard, the Obotrite lands were partitioned between Pribislav and Niklot (1090–1160), both chiefs of the Obotrites. Some sources consider the death of Canute to be a murder committed by Magnus; some attribute it to Niels himself. The death provoked a civil war that intermittently lasted until 1157, ending only with the triumph of Canute's posthumous son Valdemar I. The fate of Canute and his son's victory formed the background for his canonisation in 1170, which was requested by King Valdemar. His feast day ("Knutsdagen") is celebrated on the day of his death, January 7.
