Input: Question: On what date was the treaty signed that separated Nemirseta from Germany? Passage:A part of the Province of East Prussia until after World War I, in 1920 Nemirseta was with the Klaipėda Region (Memelland) separated from Germany according to the Treaty of Versailles. It was put under administration of the League of Nations and controlled by French forces, until the 1923 Klaipėda Revolt, after which it was annexed by Lithuania. For a brief period Nemirseta again became a border checkpoint, when Lithuanian Foreign Minister Juozas Urbšys under pressure of Nazi Germany in March 1939 signed an agreement after which the Klaipėda Region was reannexed to the German nation. The secret protocol of the Molotov–Ribbentrop Pact allocated it to the German sphere of influence.
