Final answer:
Germany gained the support of their people after WW1 by the Nazis promising to reject the Versailles Treaty, rebuild the military, and restore the economy. Extensive propaganda, public works, and the portrayal of Germans as victims also helped consolidate Nazi power and popularity amongst the populace.
Step-by-step explanation:
After World War I, Germany faced a myriad of challenges including a humiliating defeat, the harsh conditions of the Versailles Treaty, and a devastated economy. The rise of fascism and the Nazi Party in Germany was fueled by the people's desire for a restoration of national pride, economic stability, and a reversal of the terms imposed by the Treaty. The Great Depression further destabilized the Weimar government, leading to the attraction of extreme ideologies that promised to fix these issues. Adolf Hitler and the Nazis capitalized on these sentiments by offering to rebuild the military, reject the Versailles Treaty, and improve economic conditions, which culminated in their significant electoral successes in the early 1930s.
Nazism also sought to win the support of ordinary Germans through extensive propaganda and public works projects like the construction of the Autobahn, which created jobs and improved infrastructure. Hitler's refusal to continue paying war reparations and the rearmament that violated the Versailles Treaty helped gather widespread national support. The Nazis also exploited nationalist sentiments and racial theories to gain political power, entrench support, and facilitate the marginalization of their political and racial enemies.
