The crusades of the 13th century in the Baltic region represented a conflict between different social systems: on the one hand, the feudal system of Western Europe, and on the other hand, a social model closer to that of the Viking Age society. In the military conflicts of the early 13th century, the Curonians made use of the tactics and experience developed during the Viking Age. That included swift attacks at sea and a rapid change from fighting at sea to fighting on land, tactics that seriously threatened the crusader forces in the Baltic, including Riga, which was attacked by the Curonians on 13 July 1210.
