Ostsiedlung
Background

A call for a crusade against the Wends in 1108, probably coming from a Flemish clerk in the circles of the archbishop of Magdeburg, which included the prospect of profitable land gains for new settlers, had no noticeable effect and resulted in neither a military campaign nor a movement of settlers into the area.

Although the first settlers had already arrived in 1124, being mostly of Flemish and Dutch origin, they settled south of the Eider river, followed by the conquest of the land of the Wagri in 1139, the founding of Lübeck in 1143 and the call by Count Adolf II of Schauenburg to settle in Eastern Holstein, and Pomerania in the same year.

Weakened by ongoing internal conflicts and constant warfare, the independent Wendish territories finally lost the capacity to provide effective military resistance. From 1119 to 1123, Pomerania invaded and subdued the northeastern parts of the Lutici lands. In 1124 and 1128, Wartislaw I, Duke of Pomerania, at that time a vassal of Poland, invited bishop Otto of Bamberg to Christianize the Pomeranians and Liutizians of his duchy. In 1147, as a campaign of the Northern Crusades, the Wendish Crusade was mounted in the Duchy of Saxony to retake the marches lost in 983. The crusaders also headed for Pomeranian Demmin and Szczecin, despite these areas having already been successfully Christianized. The Crusade caused widespread devastation and slaughter.
