Memelland
The northern part of East Prussia beyond the Neman River was detached from East Prussia at the Paris Peace Conference of 1919, dividing the territories inhabited by Prussian Lithuanians between Weimar Germany and the Klaipėda Region (Memelland) under the administration of the Council of Ambassadors, which was formed to enforce the agreements reached in the Treaty of Versailles. The organisation "Deutsch-Litauischer Heimatbund" () sought reunification with Germany or to create an independent state of Memelland and had a membership of 30,000 individuals. Two dozen pro-Lithuanian representatives of the Prussian Lithuanian National Council signed the Act of Tilsit, asking to unite the Klaipėda Region with Lithuania; the idea was not supported by the majority of Prussian Lithuanians. World War I was followed by severe economical hardships and inflation in Germany. In 1923, the Republic of Lithuania occupied the Klaipėda Region during the Klaipėda Revolt.
