Ministry of the Reichswehr in the context of "Bendlerblock"

The Oberkommando der Wehrmacht (German: [ˈoːbɐkɔˌmando deːɐ̯ ˈveːɐ̯ˌmaxt] ; abbreviated OKW [oː kaːˈve] Armed Forces High Command) was the supreme military command and control staff of Nazi Germany during World War II, that was directly subordinated to Adolf Hitler. Created in 1938, the OKW replaced the Reich Ministry of War and had nominal oversight over the individual high commands of the country's armed forces: the army (Heer), navy (Kriegsmarine) and air force (Luftwaffe). With the start of World War II, tactical control of the Waffen-SS was also exercised by it. There was no direct chain of command between the OKW and the other High Commands.

Rivalry with the different services' commands, mainly with the Army High Command (OKH), prevented the OKW from becoming a unified German General Staff in an effective chain of command, though it did help coordinate operations among the three services. During the war, the OKW acquired more and more operational powers. By 1942, the OKW had responsibility for all theatres except for the Eastern Front. However, Hitler manipulated the system in order to prevent any one command from taking a dominant role in decision making. This "divide and conquer" method helped put most military decisions in Hitler's own hands, which at times included even those affecting engagements at the battalion level, a practice which, due to bureaucratic delays and Hitler's worsening indecision as the war progressed, would eventually contribute to Germany's defeat.

Wilhelm Bodewin Johann Gustav Keitel (German pronunciation: [ˈvɪlhɛlm ˈkaɪtl̩]; 22 September 1882 – 16 October 1946) was a German field marshal who held office as chief of the Oberkommando der Wehrmacht (OKW), the high command of Nazi Germany's armed forces, during World War II. He signed a number of criminal orders and directives that led to numerous war crimes.

Keitel's rise to the Wehrmacht high command began with his appointment as the head of the Armed Forces Office at the Reich Ministry of War in 1935. Having taken command of the Wehrmacht in 1938, Adolf Hitler replaced the ministry with the OKW and Keitel became its chief. He was reviled among his military colleagues as Hitler's habitual "yes-man".

Gustav Noske (9 July 1868 – 30 November 1946) was a German politician of the Social Democratic Party (SPD). He served as the first Minister of Defence (Reichswehrminister) of the Weimar Republic between 1919 and 1920. Noske was known for using army and paramilitary forces to suppress the socialist/communist uprisings of 1919.
