On May 10 , 1945 , in Crostwitz , after the Red Army ’s invasion , the Domowina Institution renewed its activity . In 1948 , the Landtag of Saxony passed an Act guaranteeing protection to Sorbian Lusatians ; in 1949 , Brandenburg resolved a similar law . In the times of the German Democratic Republic , Sorbian organizations were financially supported by the country , but at the same time the authorities encouraged Germanization of Sorbian youth as a means of incorporating them into the system of " building Socialism " . Sorbian language and culture could only be publicly presented as long as they promoted socialist ideology . For over 1000 years , the Sorbs were able to maintain and even develop their national culture , despite escalating Germanization and Polonization , mainly due to the high level of religious observance , cultivation of their tradition and strong families ( Sorbian families still often have five children ) . In the middle of the 20th century , the revival of the Central European nations included some Sorbs , who became strong enough to attempt twice to regain their independence . After World War II , 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 Sorbs were organized 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 postulated about ten petitions to the United Nations , the United States , Soviet Union , the United Kingdom , France , Poland and Czechoslovakia , however , it did not bring any results . On April 30 , 1946 , the Lusatian National Committee also postulated a petition to the Polish Government , signed by Pawoł Cyž – the minister and an official Sorbian delegate in Poland . There was also a project of proclaiming a Lusatian Free State , whose Prime Minister was supposed to be a Polish archaeologist of Lusatian origin - Wojciech Kóčka . The most radical postulates in this area ( " Na swobodu so ńečeka , swobodu so beŕe ! " ) were expressed by the Lusatian youth organization - Narodny Partyzan Łužica . Similarly , in Czechoslovakia , where before the Potsdam Conference in Prague , 300,000 people demonstrated for the independence of Lusatia . The endeavours to separate Lusatia from Germany did not succeed because of various individual and geopolitical interests
