Commander-in-Chief of the Luftwaffe. On 19 July 1940, following the German victory in the
Battle of France, Adolf Hitler held a
ceremony in which he promoted twelve generals to the newly awarded rank of . During the same ceremony, Göring was elevated to the newly created rank of , a symbolic move to highlight his seniority over other commanders and to fulfill his ambitions for prestige, though it conferred no additional authority. This was done in order to ensure that the (, abbreviated in German to OKW), which was headed by Hitler, would retain overall control and authority over the German military. Earlier, on the day
Germany invaded Poland, Hitler designated Göring as his successor, a status underscored by a 1941 decree that empowered Göring to act as Hitler's deputy with full freedom of action in the event Hitler was incapacitated. Nevertheless, on 23 April 1945, when
Göring suggested to Hitler that he assume leadership of the crumbling remains of Nazi Germany, Hitler relieved Göring of his duties and named a new successor in
his last will and testament,
Grand Admiral Karl Dönitz. Dönitz's appointment was made on or before the day of
Hitler's suicide. ==Standards==
