Hello! During Hitlers rise to power in the early 1930's he was affiliated with the "Nationalsozialistische Deutsche Arbeiterpartei" In English this directly translates to "National Socialist German Workers Party". He quickly rose in the ranks of the organization due to his passion for their extreme right wing beliefs. A concoction of events such as communism in Germany, the great depression, and a weak government allowed Hitler to become chancellor in 1933 and ultimately the Dictator "Fuhrer" in 1934.
According to the U.S. Constitution, the federal government has limited powers, while the states retain most powers not expressly given to the federal government.
