Circipania (German: Circipanien, Zirzipanien) was a medieval territory in what is now northeastern Germany. The name derives from Latin circum (around) and Pane (the Peene River). The region was enclosed roughly by the upper Recknitz, Trebel and Peene rivers, the western border ran east of Güstrow. The region developed in the 10th and 11th centuries, when it was the tribal territory of the Circipanes (German: Circipanen, Zirzipanen), a West Slavic tribe which along with the neighboring tribes was a part of the Lutici federation. The main burghs were Teterow, Malchin, and Demmin.
In 936, the Circipania was incorporated into the Billung March of the Holy Roman Empire. 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 Obodrites successfully invaded Circipania and made it a province of their realm. 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. The last of the territory was invaded by Mecklenburg and subdued in the early 1230s.
