inflation in Germany and Austria in the 1920s. I quote from a PBS website on this:
Before World War I Germany was a prosperous country, with a gold-backed currency, expanding industry, and world leadership in optics, chemicals, and machinery. The German Mark, the British shilling, the French franc, and the Italian lira all had about equal value, and all were exchanged four or five to the dollar. That was in 1914. In 1923, at the most fevered moment of the German hyperinflation, the exchange rate between the dollar and the Mark was one trillion Marks to one dollar, and a wheelbarrow full of money would not even buy a newspaper. Most Germans were taken by surprise by the financial tornado.
. . . .
In retrospect, you can trace the steps to hyperinflation, but some of the reasons remain cloudy. Germany abandoned the gold backing of its currency in 1914. The war was expected to be short, so it was financed by government borrowing, not by savings and taxation. In Germany prices doubled between 1914 and 1919.
After four disastrous years Germany had lost the war. Under the Treaty of Versailles it was forced to make a reparations payment in gold-backed Marks, and it was due to lose part of the production of the Ruhr and of the province of Upper Silesia. The Weimar Republic was politically fragile.
But the bourgeois habits were very strong. Ordinary citizens worked at their jobs, sent their children to school and worried about their grades, maneuvered for promotions and rejoiced when they got them, and generally expected things to get better. But the prices that had doubled from 1914 to 1919 doubled again during just five months in 1922. Milk went from 7 Marks per liter to 16; beer from 5.6 to 18. There were complaints about the high cost of living. Professors and civil servants complained of getting squeezed. Factory workers pressed for wage increases. An underground economy developed, aided by a desire to beat the tax collector.
