The last prince of Lippe was forced to abdicate in 1918 after the end of World War I when Germany became a republic, his country became a Freistaat (Free State) in the German republic. In 1932 the state was divided into two districts, Detmold and Lemgo.
In 1973 the two districts Lemgo and Detmold were merged to the district Lippe.
The coat of arms show the traditional symbol of the state of Lippe, the rose, as the district covers nearly the same area as the historic country. In the middle of the rose 16 stamens symbolize the 16 cities and municipalities of the district. The coat of arms was granted in 1973.
Despite the relatively small size of Lippe, the Lippish rose is also one of only three symbols included in the coat of arms of the state of North Rhine-Westphalia.
