In 1933, as Adolf Hitler assumed power in Germany, Sudeten German pro-Nazi leader Konrad Henlein founded Sudeten German Party (SdP) that served as the branch of the Nazi Party for the Sudetenland.[11] By 1935, the SdP was the second largest political party in Czechoslovakia.[11] Shortly after the anschluss of Austria to Germany, Henlein met with Hitler in Berlin on 28 March 1938, where he was instructed to raise demands unacceptable to the Czechoslovak government led by president Edvard Beneš.
