Under the Weimar Republic, Germany's economy struggled after foreign investors withdrew support, sending the country into trouble. Unemployment rose to over 3 million and nationalism increased as the people blamed outsiders. In the 1930s, the Nazi party gained popularity by promising to restore Germany's power and prosperity. After Hindenburg appointed Hitler as Chancellor in 1933, the Nazi party became the sole party and Hitler consolidated power. The German people supported these moves as they wanted a strong leader to improve their situation and make Germany powerful again through military and territorial expansion in the late 1930s.
