Reichsmarschall (literal translation: Marshal of the Realm) was the highest rank in the armed forces of Nazi Germany during World War II after the position of Supreme Commander held by Adolf Hitler.
The rank of Reichsmarschall was originally created before the 12th century, during the time of the Holy Roman Empire. Historically, holding the rank of Reichsmarschall was neither unique nor as prestigious as it was during World War II. During the time of the German Empire and World War I, no one in the German armed forces held this rank.
During World War II, Hermann Göring was the only man to hold the rank of Reichsmarschall, having been promoted on 19 July 1940 by Adolf Hitler. Göring, who was the Commander-in-Chief of the Luftwaffe, held many other prestigious titles, such as Reich Master Hunter and Commissioner Plenipotentiary of the Four-Year Plan.
Hitler appointed Göring to the rank of Reichsmarschall primarily to denote him as senior to the other commanders of the Wehrmacht's general staff promoted the same day. Hitler had chosen Göring as his successor to leadership of the Reich; and one reason for Göring's promotion was so that in the event of Hitler's death, a clear line of succession from the military would have already been established. Nevertheless in April 1945, following a telegram by Göring asking Hitler for permission to assume leadership of the Reich, Hitler relieved Göring of his duties and named a new successor. This was Grand Admiral Karl Dönitz, who was specifically appointed as successor by Hitler himself on or before April 30, 1945. Dönitz was however only notified of his appointment as successor on May 1, 1945 by Martin Bormann and Joseph Goebbels.
