He was also Stellvertretender Reichsprotektor (Deputy/Acting Reich-Protector) of Bohemia and Moravia, in what is now the Czech Republic.

Heydrich was attacked in Prague on 27 May 1942 by a British-trained team of Czech and Slovak soldiers who had been sent by the Czechoslovak government-in-exile to kill him in Operation Anthropoid. He died from his injuries a week later. Intelligence falsely linked the assassins to the villages of Lidice and Lezaky. Lidice was razed to the ground
