The Führer Headquarters (Führerhauptquartiere in German), abbreviated FHQ, is a common name for a number of official headquarters used by the Nazi leader Adolf Hitler and various German commanders and officials throughout Europe during the Second World War. Perhaps the most widely known headquarters was the Führerbunker in Berlin, Germany, where Hitler committed suicide on 30 April 1945. Other notable headquarters are the Wolfsschanze (Wolf's Lair) in East Prussia, where Claus von Stauffenberg in league with other conspirators attempted to assassinate Hitler on 20 July 1944, and Hitler's private home, the Berghof, at Obersalzberg near Berchtesgaden, where he frequently met with prominent foreign and domestic officials.
At the beginning of World War II there were no permanent headquarters constructed for the German supreme leader, the Führer. Hitler visited the frontlines by using either aeroplane or his special train, the Führersonderzug; thus, the Führersonderzug can be considered as the first of his field headquarters. The first permanent installation which became a Führer Headquarters was the Felsennest, which was used by Hitler during the Battle of France in May, 1940. Hitler actually spent very little time in Berlin during the war, and the dwellings he most frequently used were the Berghof and the Wolfsschanze, spending more than 800 days at the latter.
