After World War II according to the Potsdam Agreement, Lusatia was divided between Allied-occupied Germany (Soviet occupation zone) and the Republic of Poland along the Oder–Neisse line. Poland's communist government expelled all remaining Germans and Sorbs from the area east of the Neisse river during 1945 and 1946. The Lusatian National Committee in Prague claimed the right to self-government and separation from Germany and the creation of a Lusatian Free State or attachment to Czechoslovakia. The majority of the Sorbian intelligentsia was organised in the Domowina, though, and did not wish to split from Germany. Claims asserted by the Lusatian National movement were postulates of joining Lusatia to Poland or Czechoslovakia. Between 1945–1947 they produced about ten memorials to the United States, Soviet Union, Great Britain, France, Poland and Czechoslovakia; however, this did not bring any results. On 30 April 1946, the Lusatian National Committee also submitted a petition to the Polish Government, signed by Paweł Cyż – the minister and an official Sorbian delegate in Poland. There was also a project to proclaim a Lusatian Free State, whose Prime Minister was intended to be the Polish archaeologist of Lusatian origin, Wojciech Kóčka.
