In this timeline, Adolf Hitler is not given German citizenship in 1932, so he is unable to run in the German presidential election in 1933. As a result, Theodor Dusterberg, the leader of the Stahlheim (the armed wing of the DNVP), becomes Chancellor of Germany. The monarchist DNVP then sets about restoring the German monarchy, basing their plans on the fact that large parts of the German society still held warm feelings towards the Hohenzollerns.
However, Kaiser Wilhelm II sticks to his pledge that he would not return to Germany until the pre-1918 borders are restored and Crown Prince Wilhelm III is deemed to be unworthy of the crown, so the DNVP places Wilhelm III's son and the Kaiser's grandson, the relatively young Wilhelm IV, on the throne as a constitutional monarch. In this timeline, Wilhelm IV does not renounce his succession rights because he does not fall in love with Dorothea von Salviati, so he is still eligible for the German throne, along with his children.
How would the world react to the restoration of the German monarchy without Wilhelm II, especially Britain and France, and how does the new monarchy change Germany's future?
