German Parliamentary Politics - Hitler's Greatest Challenge?

In 1923, the same year that Hitler tried his push, a guy named Gustav Stressmann was elected chancellor of Germany. While he was in office, he pushed for German to join with France into that European Union thing. This actually might have happened if it hadn't been for a guy named Alfred Hugenberg. He didn't like the Nazis, but he saw them as the only way for conservatives to win at the ballot box. The Nazi alliance was successful at stopping any chance this head of reality from happening.
