Weimar Republic
Germany's first democracy, born in defeat in 1919 and dead in 1933, and the standing case study in how republics fail.

It is named after a small town in Thuringia for an unflattering reason: in early 1919 Berlin was too violent to hold a constitutional assembly in, so the delegates went to Weimar, the town of Goethe and Schiller, and drafted there. The republic never quite shook the impression that it was an improvisation carried out somewhere else, by people apologizing for a defeat they had not caused.
Born in a lie
The German army was beaten in the field in 1918, and its own high command said so, telling the Kaiser at the end of September that an armistice was needed at once. Then Ludendorff and Hindenburg let civilians sign it. Within months they were promoting the claim that the army had been stabbed in the back by socialists, Jews, and republicans at home. It was false and enormously effective, and it meant that the republic's founding act, ending a catastrophic war, was recast as its founding crime. The politicians who signed the armistice were called the November criminals, and two of them were assassinated.
A constitution with a trapdoor
The 1919 constitution was among the most democratic in the world on paper: universal suffrage at twenty, proportional representation, referenda, a directly elected president. Two features proved fatal. Pure proportional representation with no threshold produced fragmented parliaments in which stable coalitions were extremely hard to build. And Article 48 let the president rule by emergency decree without parliament.
Article 48 was used over a hundred times in the early crisis years, which normalized it. From 1930 Chancellor Heinrich Brüning governed almost entirely by decree because he could not command a majority, so by the time Hitler was appointed in January 1933 the machinery for ruling without parliament had been running for nearly three years, operated by conservatives trying to keep him out.
The crises
The hyperinflation of 1923 was the trauma. Triggered by the French occupation of the Ruhr and the government's decision to print money to support striking workers, it destroyed savings, pensions, and insurance policies, and it taught the German middle class that the republic could not protect what it owned.
Then came five good years. The currency was stabilized, American loans arrived under the Dawes Plan, Gustav Stresemann negotiated Germany back into respectable diplomacy, and Berlin became the most creative city in Europe. Extremist parties shrank. In the May 1928 election the Nazis took 2.6 percent.
The Depression ended it. Unemployment passed six million. The Nazi vote went from 2.6 percent in 1928 to 18.3 in 1930 to 37.3 in July 1932, and the Communists rose alongside them, so that by late 1932 a majority of the Reichstag consisted of parties committed to destroying the Reichstag. Government by decree was no longer an emergency measure but the only available method.
How it ended
Not by revolution. Hitler was appointed chancellor on 30 January 1933 by President Hindenburg, at the urging of conservatives led by Franz von Papen who were sure they could box him in, with only two other Nazis in a cabinet of eleven. The Reichstag fire four weeks later supplied the pretext for an emergency decree suspending civil liberties, and the Enabling Act of 23 March handed legislative power to the cabinet.
Weimar is the reference case for a reason. It did not fall to a coup or an invasion. It was dismantled step by step using its own legal instruments, by people who thought they were managing a crisis, in a country with a literate population, a free press, and independent courts. Postwar Germany built its constitution around that memory: a five percent electoral threshold, no rule by decree, and a constructive vote of no confidence that makes it impossible to bring down a government without agreeing on a replacement.
