Sorbian languages
This era came to an end during the Nazi regime in Germany, when all Sorbian organisations were abolished and forbidden, newspapers and magazines closed, and any use of the Sorbian languages was prohibited. During World War II, some Sorbian activists were arrested, executed, exiled or sent as political prisoners to concentration camps. From 1942 to 1944 the underground Lusatian National Committee was formed and was active in Nazi-occupied Warsaw.
