1916
The Olympics were originally planned to be held within Berlin in 1916 officially the Sixth Olympic games. However with the outbreak of World War I in 1914, the International Olympic Committee (IOC) decided to take the drastic step of canceling the Sixth Olympiad all together. While offers to host the Olympics else where (including Chicago, London, and Madrid) rolled in the IOC deemed their cancelation to be final.
1930-1931
After almost a decade after the end of the First World War, Germany is once again awarded the Olympics, this time Berlin is selected to be the host for the 1936 Olympics. For a self-proclaimed non-political organization, the IOC had obviously political intentions with the placement of the Eleventh Olympiad as a means to signify the reemergence of Germany as on the world stage after their defeat in WWI.
While the rise of the Nazi Empire could have hardly been accurately predicted, we postulate that had the IOC put more effort into researching the German population and mentality, instead of trying to reenergize a nation, that they might have been able to detect the dangerously fast rising German nationalism and pre-empted any future debates of boycott after Hitler's rise to power.
1933 - 1935
Rise of the Third Reich
Adolf Hitler become Chancellor of Germany in early 1933. Initially Hitler was not all together interested in making the Olympic Ceremonies a large affair. However his Minister of Propaganda Goebbels convinced him of the potential of the Olympics to spread the ideals of the Third Reich while simultaneously showing the superiority of the Aryan race.
