Circipania

The region was enclosed roughly by the upper Recknitz, Trebel and Peene rivers, the western border ran east of Güstrow.

The Circipanes were one of the four constituent tribes of the Lutici federation centered on Rethra, which started a successful uprising in 983.

Rid of the empire's overlordship, the Circipanes stayed with the Liutizians until the federation broke apart due to internal struggles in the 1050s, culminating dissolution in 1057.

The Redarians and Tollensians opposed the Circipanes and Kessinians struggling for more influence within the federative administration, and allied with the Obodrites.

The internal struggles had weakened the area, such that in the following year it became the target of numerous expeditions of an expansive Holy Roman Empire during their Wendish Crusade in 1147), then by Denmark in the raid of 1170, and finally by the Duchy of Pomerania which subdued and incorporated the area into Pomerania-Demmin in the late 12th century.
