Sudeten German uprising (Czech: sudetoněmecké povstání) in September 1938 was a rebellion of Sudeten Germans against Czechoslovak authorities in Sudetenland, supported by an organized action orchestrated by Sudeten German Party (SdP) chaired by Konrad Henlein. Therefore, the uprising is also referred to as the Henlein's coup (or coup attempt; Czech: henleinovský puč).
