The time of the soldiers and Nazis
From 1929, the German army - especially the artillerymen - became interested in long-range rockets. These were seen as a way of getting around the prohibitions imposed by the Treaty of Versailles.

The military took advantage of the amateur rocket societies' difficulties to recruit their most competent members; Von Braun was recruited in 1932. The Nazis, who came to power in 1933, marked the beginning of a series of secret research into rockets. In addition, the credit available for the development of new weapons suddenly swelled.
