Fritz-Dietlof von der Schulenburg acted as a bridge to all circles within the conspiracy to assassinate Hitler.
In 1937 Schulenberg became Vice-President of the Berlin Police Force.
In 1938, he joined the conspiracy and supported the first coup attempt in September.
During the winter of 1938-39, he worked closely with Claus von Staffenberg's uncle, Count Ukxull, planning another coup attempt.
Schulenburg helped General Ludwig Beck, and professors Johannes Popitz and Jens Jessen draft the "Basic Law of the State." He made contact with Dr. Carl Goerdeler, worked closely with Colonel Henning von Tresckow, and recruited Claus von Stauffenberg into the conspiracy. He acted as liaison between Stauffenberg and leading social democrat Julius Leber, between the army conspirators and the Kreisau Circle, and maintained contact with the Paris conspirators through Colonel Caesar von Hofacker.
On July 20, 1944, Schulenburg participated in Colonel von Stauffenberg's uprising and was later arrested.
On August 10, 1944, Schulenburg was tried by the People's Court. He refused to divulge any names from the secret list he had drawn up of men assigned to serve in the new government.
