|Historical era||Interwar period|
The Free State of Waldeck-Pyrmont (German: Freistaat Waldeck-Pyrmont), later the Free State of Waldeck (Freistaat Waldeck), was a constituent state of the Weimar Republic. It was created following the German Revolution which forced Prince Friedrich of Waldeck and Pyrmont along with the other German monarchs to abdicate.
On 30 November 1921, following a local plebiscite, the city and district of Pyrmont were detached and incorporated into the Prussian province of Hanover. The remainder of the State was incorporated into the Free State of Prussia in 1929, following another plebiscite, and became part of the province of Hesse-Nassau. This territory is today part of the District of Waldeck-Frankenberg in Hesse.
