Answer
**Prague, capital of Czechoslovakia, the primary target of Reinhard Heydrich, appointed "Protector of Bohemia and Moravia" by the Nazis in 1941. Heydrich led a brutal regime aimed at suppressing Czech culture and resistance. His systematic persecution, including mass arrests, executions, and destruction of Czech landmarks, earned him the moniker "Butcher of Prague" and galvanized widespread resistance against Nazi occupation.**
