Lippe (later Lippe-Detmold and then again Lippe) was a historical state in Germany, ruled by the House of Lippe. It was located between the Weser river and the southeast part of the Teutoburg Forest.
The Free State of Lippe (German: Freistaat Lippe) was a German state formed after the Principality of Lippe was abolished following the German Revolution of 1918.
After the end of World War II, Lippe was restored. This autonomy ended in January 1947, when the Control Commission for Germany – British Element (CCG/BE) incorporated Lippe into the new German state of North Rhine-Westphalia created three months earlier.
