German general and minister of war (1933–38) in the National Socialist government of Adolf Hitler (Hitler, Adolf). He was one of Hitler's most willing collaborators among the old-line officer corps.

A general staff officer during World War I, Blomberg was named chief of staff of the Stuttgart army area (1921), head of the department of military training (1925), and military commander in chief in East Prussia (1929). In January 1933 he was appointed German minister of defense in the new Hitler government and retained office until early 1938—as minister of war after 1935 and, concurrently, commander in chief of the Wehrmacht (German armed forces). An unquestioning follower of Hitler, so compliant as to be given the nickname “Rubber Lion,” he played a consenting role in the purge of the SA (storm troopers) of 1934, and in August 1934 imposed on the army an oath of personal allegiance to Hitler. In 1936 he was created field marshal. A personal domestic scandal was the immediate cause of his resignation as war minister in January 1938.
