 Administrative structures changed again after the First World War when the Treaty of Versailles stipulated, among other things, that Homburg had to be ceded to the British- and French-occupied Saar.The rest of the Homburg district that was then still within Weimar Germany now functioned as a branch of Waldmohr in the Kusel district, and was permanently grouped into the Kusel district in 1940.The Canton of Landstuhl was a branch of the "Bezirksamt" of Kaiserslautern, but had been fully merged into Kaiserslautern by 1938.
