Hitler and the Nazi party rose to power in Germany for several interrelated reasons: - Germans were disillusioned after World War 1 defeat and economic hardship, leading many to support extremist right-wing groups like the Nazis. - In the early 1920s, the Nazis gained popularity by opposing the Treaty of Versailles and using force against communists. - After an unsuccessful coup in 1923, the Nazis rebuilt support legally by focusing on propaganda, traditional values, and gaining backing from big business. - The Great Depression starting in 1929 led to rising unemployment and hyperinflation, increasing fears and support for the Nazis who blamed Jews and communists.
