Formally created in 1938 and 1939, the Baum group was a German anti-Fascist resistance organization. Initially its work consisted of making and distributing anti-Fascist propaganda, but on May 18, 1942, the Baum group joined the effort to set fire to an anti-Soviet exhibit at a public park in Berlin. The damage was minimal and shortly thereafter, the Gestapo arrested hundreds of Jews in retaliation and twenty-two members of the Baum group were executed.
