ENAs long as the end of WWI on the area of the eastern Prussia condensed communities of the evangelical Prussian Lithuanians (114 thousand) and Masuriens (350 thousand) used to live. As a result of incorporation of Memelland to Lithuania in 1923 and the souther Mazury region to Poland in 1920 (the administrative unit of Działdowo) this community was within the borders of the states that it had originally come from. These areas came to be joined to Germany again (1939-1945). After WWII Memelland became a part of Lithuania. The whole of Mazury was incorporated by Poland. As a result of the migration process to Germany (since the escape of 1944) a gradual process of break-up and disintegration of both communities has taken place. Currently ca 4 thousand of autochthonous peoples live in their motherland region - Memelland and ca 6 thousand in the region of Mazury.
