Klaipėda Region

The Klaipėda Region (Lithuanian: Klaipėdos kraštas) or Memel Territory (German: Memelland or Memelgebiet) was defined by the Treaty of Versailles in 1920 and refers to the most northern part of the German province of East Prussia, when as Memelland it was put under the administration of the Council of Ambassadors. The Memel Territory, together with the other parts severed from Germany, the Saar and Danzig, was to remain under the control of the League of Nations until a future day when the people of these regions would be allowed to vote on whether the land would return to Germany or not.

The original Prussian Scalovian and Curonian territory was by the duke of Masovia requested and by the emperor and pope confirmed to be conquered, Christianized and to be administered by the Teutonic Knights, who constructed Memelburg ("Memel Castle") and the city of Memel (now usually known by its Lithuanian name Klaipėda). In 1422, a border was drawn up between Prussia and Lithuania under the Treaty of Melno, and this border existed up to 1918.
