During World War II, Czechoslovakia was divided into four different regions, each administered by a different authority: Sudetenland (Germany), Protectorate of Bohemia and Moravia, the Slovak State, and Carpathian Ruthenia and southern Slovakia (Hungary).
As a result, the Holocaust unfolded differently in each of these areas: The Holocaust in the Sudetenland The Holocaust in Bohemia and Moravia The Holocaust in Slovakia The Holocaust in Hungary
