Final answer:
Adolf Hitler promised to reclaim Germany's losses following World War I, countering the severe conditions imposed by the Treaty of Versailles. His commitment to restoring Germany's territory, economic stability, national pride, and military strength appealed to a nation burdened by war guilt, reparations, and political instability, which subsequently led to World War II.
Step-by-step explanation:
Among the multiple influences that rallied the people of Germany behind the Nazi Party was the promise by Adolf Hitler to reclaim what Germany had lost post-World War I. The Treaty of Versailles had profound impacts, placing the blame for the war squarely on Germany, demanding excessive war reparations, reducing Germany's territory, and downsizing its military. The Weimar Republic faced hyperinflation, unemployment, national debt, and political instability, which Hitler exploited.
Inspired by Mussolini's march on Rome, Hitler used his political leverage to promise the reversal of the humiliation experienced at Versailles. World War II was largely seen as a continuation of World War I for Germany due to these unsolved issues. The Nazi regime vowed to reestablish Germany's power by reneging on the oppressive aspects of the Versailles Treaty, addressing the 'stab-in-the-back' myth, and restoring national pride and economic stability. Indeed, Hitler capitalized on the 'stab-in-the-back' myth, which blamed 'Jewish saboteurs' and 'Bolshevik agents' for Germany's defeat in World War I.
Furthermore, the division of Germany post-World War II into occupied zones as per the Declaration on Liberated Europe and later agreements at Yalta and Potsdam confirmed the dismantling of the German war machine and prepared for the management of war reparations through the allocation of industry and resources to the victors. Hitler's assurance to take back what Germany had lost translated into a dangerous militaristic and expansionist ideology that would once again plunge Europe into warfare.
