World War II: Nazi Germany, the Holocaust, and the Postwar International Order
WWI’s end didn’t produce lasting peace but planted seeds of a larger conflict: the **Treaty of Versailles (1919)** imposed harsh reparations (132 billion gold marks), territorial losses, and military restrictions on Germany (widely seen by Germans as the “war guilt lie”), generating intense nationalist resentment amid Weimar Republic economic crises (hyperinflation 1921–23; Great Depression after 1929), providing the social soil for the Nazi movement.
## Nazism’s Ideology and Path to Power
Nazism fused extreme nationalism, racial antisemitism (defining Jews as a “racial danger” rather than religious dissenters), social Darwinism, anti-communism, and utopian promises of “national community” (Volksgemeinschaft). Hitler achieved power legally through 1932–33 elections and political maneuvering, then established one-party dictatorship via the Enabling Act.
**Holocaust historical record**: The 1942 Wannsee Conference institutionalized the “Final Solution.” Extermination camps like Auschwitz-Birkenau used gas chambers for mass killing — approximately 1.1 million people died at Auschwitz (~1 million Jews). [Yad Vashem](https://www.yadvashem.org/) and the [USHMM](https://www.ushmm.org/) are the most authoritative archival institutions.
## Postwar Order: From Rubble to Cold War Structure
Post-WWII international order: **UN (1945)** replacing the failed League of Nations; **Bretton Woods system (1944)** — dollar-gold standard, IMF, and World Bank; **Marshall Plan (1948)** — US funding Western European reconstruction; **NATO (1949)** and **Warsaw Pact (1955)**. The Yalta Conference (February 1945) and Potsdam Conference demarcated postwar European spheres of influence, laying the geopolitical foundation of approximately 45 years of Cold War.
