The story begins with defeat in the First World War. In November 1918 sailors mutinied at Kiel, revolution spread, and Kaiser Wilhelm II abdicated on 9 November 1918. The Social Democrat Friedrich Ebert led the new republic, and an armistice ended the war on 11 November. A constitution was drafted at Weimar in 1919, creating a democratic system with proportional representation and Article 48, which let the President rule by emergency decree. From the start the republic carried two burdens: the "stab-in-the-back" myth (the false claim that the army was betrayed by politicians and Jews rather than defeated militarily) and the Treaty of Versailles, signed on 28 June 1919, which imposed war-guilt (Article 231), reparations later fixed at 132 billion gold marks (1921), and heavy territorial and military losses.
The early years were violent and unstable. The Spartacist uprising of January 1919 was crushed and its leaders Karl Liebknecht and Rosa Luxemburg were murdered. The right attempted the Kapp Putsch in March 1920. When Germany defaulted on reparations, French and Belgian troops occupied the Ruhr in January 1923, and the government's response of printing money produced hyperinflation, with the mark collapsing to trillions per US dollar by November 1923. It was in this chaos that Hitler, leader of the small Nazi Party (NSDAP), attempted the Munich (Beer Hall) Putsch on 8-9 November 1923. It failed, and he was jailed, using the time to write Mein Kampf.
The Wall Street Crash of October 1929 ended that stability. American loans were recalled and unemployment soared, reaching roughly 6 million by early 1933. Stresemann had died in October 1929. From 1930 Chancellor Heinrich Bruning governed by presidential decree under Article 48 rather than parliamentary majority, normalising rule without the Reichstag. Mass unemployment and fear of communism drove voters to the extremes. The Nazis won 18 per cent of the vote in September 1930 and became the largest party in July 1932 with 37 per cent, though their share dipped to 33 per cent in November 1932. Hitler offered simple promises: work, bread, national revival and an enemy to blame.
Behind the scenes, conservative elites believed they could use and contain Hitler. After intrigues involving Franz von Papen and General Kurt von Schleicher, the aging President Paul von Hindenburg appointed Hitler Chancellor on 30 January 1933. Consolidation then came swiftly. The Reichstag Fire on 27 February 1933 was blamed on communists and used to pass the Reichstag Fire Decree, suspending civil liberties. After the March 1933 election the Enabling Act (23 March 1933) gave Hitler power to make laws without the Reichstag, the legal foundation of dictatorship. Trade unions were banned and other parties dissolved by mid-1933 (Gleichschaltung, or coordination). The Night of the Long Knives (30 June 1934) destroyed the SA leadership, including Ernst Rohm, reassuring the army. When Hindenburg died on 2 August 1934, Hitler merged the offices of Chancellor and President as Fuhrer, and the armed forces swore a personal oath to him.
The Nazi state was totalitarian in intent. Joseph Goebbels controlled propaganda; Heinrich Himmler built the SS and Gestapo; opponents were sent to concentration camps from 1933. Antisemitic policy escalated from the boycott of April 1933 to the Nuremberg Laws (1935) stripping Jews of citizenship, to the Kristallnacht pogrom of 9-10 November 1938. After war began in September 1939 this radicalised into genocide: the murder of around six million Jews in the Holocaust, decided in policy at the Wannsee Conference (January 1942). The regime was finally destroyed by total military defeat, and Hitler killed himself on 30 April 1945; Germany surrendered on 8 May 1945.
Historians debate how this happened. Intentionalists such as Karl Dietrich Bracher stress Hitler's ideology and design; structuralists or functionalists such as Hans Mommsen and Martin Broszat emphasise chaotic, competing agencies and "cumulative radicalisation". Debate also continues, since Daniel Goldhagen's 1996 work, over how far ordinary Germans shared in responsibility. For TASC source analysis, you should weigh long-term structural weaknesses against short-term contingency and individual agency.
