For military matters, Hitler used the style Führer und Oberster Befehlshaber der Wehrmacht ("Leader and Supreme Commander of the Wehrmacht"), until that addition was dropped by decree of the Führer. The style of the Head of State for use in foreign affairs was Führer und Reichskanzler ("Leader and National Chancellor") until it was changed to Führer des Grossdeutschen Reichs ("Leader of the Greater German Nation"). The title fell into disuse immediately upon Hitler's death in 1945.
