Nazism became popular in Germany by 1930 primarily due to the economic and political crises following World War I and the Great Depression. The Weimar Republic struggled to address the economic downturn, mass unemployment, and social instability, which left many Germans feeling humiliated, insecure, and desperate for change. Adolf Hitler, with his powerful speeches, promised to build a strong nation, undo the perceived injustices of the Treaty of Versailles, restore German dignity, and provide employment, presenting himself as a savior to the beleaguered population. Additionally, Nazi propaganda was highly effective in stirring hope with its nationalist, anti-Semitic, and anti-communist messages. The use of modern media, rallies, symbols like the swastika, and charismatic public appearances created a strong, unified image that attracted widespread support. The Nazi Party also capitalized on fears of communism and dissatisfaction with the democratic Weimar system by portraying it as weak and ineffective. By 1930, the Nazis had become a mass movement, gaining significant electoral support and becoming the main opposition to the established parties. In summary, the combination of economic hardship, political instability, skilled propaganda, and Hitler's charismatic leadership made Nazism gain significant popularity in Germany by 1930.
