Why was Germany's aggression successful in 1930?

1930 was a very significant year for Germany, but more specifically it was a very important year for the rise of the National Socialists (Nazis). In terms of aggression, 1930 was a powerful year of campaign, debate, and effective propaganda. These efforts in 1930 were instrumental in securing the important political positions that fortified the rise of the Nazi Party. In 1930, Wilhelm Frick was the first Nazi to become minister of a state government. Another important victory for the Nazis was securing 107 seats in the Reichstag. In 1930, the Nazis led an aggressive campaign of propaganda, which included films, street marches, demonstrations, and door-to-door dissemination of National Socialist ideals. What was this aggressive message promising, and why was it so well received?
Following the U.S. Stock Market Crash of 1929, there was a depression that gripped the world, especially Germany. In 1930, German unemployment was nearing 4 million. This same year, Hitler began to aggressively speak about the economic failure and the failure of the democratic Weimar Republic. After Germany’s serious defeat in WWI, the nation adopted a democratic system with free elections and a constitution. Hitler argued that this system was a failure. He argued that National Socialism would make Germans strong again. He promised to drive out Jews, to whom he attributed the nation’s economic and societal failure. Hitler promised to purge the leftist parasites, create jobs, help the farmer, and create a classless society full of equal opportunity. In a time when the nation was economically devastated , under-employed, and looking for someone to blame, the Germans latched on to Hitler’s solutions. The years that followed led to the rise of one of the most powerful political systems in the history of humankind.
