Rorik of Dorestad

Rorik or Hrørek was a Danish Viking, who ruled over different parts of Friesland between 841 and 873.

Since the 19th century, there have been attempts to identify him with Rurik, the founder of the Russian royal dynasty; this identification remains uncertain.

He had a brother named Harald. Harald Klak was probably their uncle, and Godfrid Haraldsson their cousin. The identity of his father remains uncertain. There are various interpretations of the primary sources on his family, particularly because names such as Harald are repeated in the texts with little effort to distinguish one holder of a name from another. But Harald Klak had at least three brothers. Anulo (d. 812), Ragnfrid (d. 814) and Hemming Halfdansson (d. 837). Any of them could be the father of the younger Harald and Rorik. Several writers have chosen Hemming for chronological reasons, estimating Rorik was born following the 810s. This remains a plausible theory, not an unquestionable conclusion.

Harald the younger had been exiled from Denmark and had raided Frisia for several years. He had entered an alliance with Lothair I who was involved in conflict against Louis the Pious, his father. Frisia was part of Louis' lands and the raids were meant to weaken him. By 841, Louis was dead and Lothair was able to grant Harald and Rorik several parts of Friesland. His goal at the time was to establish the military presence of his loyalists in Frisia, securing it against his siblings and political rivals Louis the German and Charles the Bald. The two Norsemen used islands as a main base of operations, the seat of Rorik being the island of Wieringen, while Harald operated from the island of Walcheren, and they also ruled Dorestad at this time.

In the early 840s, Frisia seemed to attract fewer raids than in the previous decade. Viking raiders were turning their attention to West Francia and Anglo-Saxon England. In 843, Lothair, Louis and Charles signed the Treaty of Verdun, settling their territorial disputes. Lothair previously needed Rorik and Harald to defend Frisia from external threats. With the seeming elimination of such threats, the two Vikings may have outlived their usefulness to their overlord. In about 844, both "fell into disgrace". They were accused of treason and imprisoned. The chronicles of the time report doubt on the accusation. Rorik would later manage to escape. Harald probably died while a prisoner.
