The Wendish Crusade was an 1147 campaign, one of the Northern Crusades and also a part of the Second Crusade, led primarily by the Kingdom of Germany inside the Holy Roman Empire and directed against the Polabian Slavs (or "Wends"). By the early 12th century, the German archbishoprics of Bremen and Magdeburg sought the conversion of neighboring pagan West Slavs to Christianity through peaceful means. During the preparation of the Second Crusade to the Holy Land, however, a papal bull was issued which supported a crusade against these Slavs. The Slavic leader Niklot preemptively invaded Wagria in June, 1147, leading to the march of the crusaders in late summer, 1147. They achieved an ostensible baptism of Slavs at Dobin and were repulsed from Demmin. Another crusading army marched on the already Christian city Szczecin, whereupon the crusaders dispersed upon arrival.
