User:Kazachstanski nygus/Pomeranian invasion of Konghelle

Pomeranian invasion of Konghelle - pomeranian expedition against Norwegian port city of Konghelle (modern day Kungälv in Sweden) made in 1135 by the Pomeranians led by Duke Ratibor, ended with a victorious battle fought on August 9 near the city with its inhabitants and the subsequent siege and destruction of the city.

The expedition was organized just before the meeting of Bolesław III Wrymouth with the Holy Roman Emperor Lothair III in Merseburg (August 15, 1135) in order to manifest the strength of Polabian Slavs.

Attack on Konghelle under the command of Duke Ratibor I, nicknamed "sea king", vassal of Bolesław III Wrymouth, was a preventive action aimed at preventing a war with the margrave of Northern March, Albert the Bear, who counted on the help of the Danish king Eric II, and by the way it was an plundering expedition.
