Lithuania Minor
The state of the Teutonic Order became Prussia in 1525 and the concept Lithuania Minor has appeared around that time (1517–26). Lithuania Minor was part of Prussia until 1701, the Kingdom of Prussia until 1871, the German Empire until 1918 and the German Reich until 1945. The political border set by the Treaty of Melno had been the same since the treaty to 1923, when the Klaipėda region (Memelland) was incorporated into Lithuania.
