As the result of the Munich Agreement of 30 September 1938 the German-speaking areas of Czechoslovakia were annexed to Nazi Germany. Many social democrats and communists from these areas who had taken a stand against the Nazis had no choice but to flee to the Czech interior. Together with many Jews and Czechs, they mostly fled to Prague. They were all aware that they would not be safe in Prague for long. They suspected that sooner or later Hitler would subsume the rest of the Czechoslovak state into German territory, which for them represented a threat to their lives.
