The Sudeten German Party was created by Konrad Henlein under the name Sudetendeutsche Heimatfront ("Front of the Sudeten German Homeland") on October 1, 1933, some months after the First Czechoslovak Republic had outlawed the German National Socialist Workers' Party (Deutsche Nationalsozialistische Arbeiterpartei, DNSAP). In April 1935, the party was renamed Sudetendeutsche Partei following a mandatory demand of the Czechoslovak government. The name was officially changed to Sudeten German and Carpathian German Party (Sudetendeutsche und Karpatendeutsche Partei) in November 1935.

With the rising power of Nazi Party in Germany, the Sudeten German Party became a major pro-Nazi force in Czechoslovakia with explicit official aim of breaking the country up and joining it to the Third Reich. By June 1938, the party had over 1.3 million members, i.e. 40.6% of ethnic-German citizens of Czechoslovakia. During last free democratic elections before the German occupation of Czechoslovakia, the May 1938 communal elections, the party gained 88% of ethnic-German votes, taking over control of most municipal authorities in the Czech borderland. The country's mass membership made it one of the largest fascist parties in Europe at the time.
