Куршская коса
Kursenieki were considered Latvians after World War I when Latvia gained independence from the Russian Empire. This consideration was based on linguistic arguments and was the rationale for Latvian claims over the Curonian Spit, Memel, and some other territories of East Prussia. Later these claims were removed. In 1923, the newly created Memel Territory separated the Curonian Spit in two parts. This separation interrupted contacts between Kursenieki. In 1933, Latvia tried to establish a cultural center for Kursenieki of the Curonian Spit where the majority of them lived, but that was opposed by Lithuania, of which Memel Territory was a part of.
