Canute Lavard
Canute Lavard (Danish: Knud Lavard) (March 12, 1096 – 7 January 1131) was a Danish prince. Later he was the first Duke of Schleswig and the first border prince who was both a Danish and a German vassal, a position leading towards the historical double position of Southern Jutland. Canute Lavard was also the ancestor of the Valdemarian Kings (Valdemarerne) and of their subsequent royal line. He was killed by his cousin Magnus, who saw him as a rival to the Danish throne, and was canonized in 1170.
Biography
Canute was the only legitimate son of Eric I of Denmark and Boedil Thurgotsdatter but as a minor he was bypassed in the election of 1104. He grew up in close contact with the noble family of Hvide, who were later on to be among his most eager supporters. In 1115, his uncle, King Niels of Denmark, placed him in charge of the Duchy of Schleswig (jarl af Sønderjylland) in order to put an end to the attacks of the Slavic Obotrites. During the next fifteen years, he fulfilled his duty of establishing peace in the border area so well that he was titled Duke of Holstein (Hertug af Holsten) and became a vassal of the Holy Roman Empire.
