war helped to dispel the fears that surrounded women's entry into the public arena. In Europe, according to Derek Aldcroft and Steven Morewood, "Nearly all countries registered some economic progress in the 1920s and most of them managed to regain or surpass their pre-war income and production levels by the end of the decade." The Netherlands, Norway, Sweden, Switzerland, and Greece did especially well, while Eastern Europe did poorly, due to the First World War and Russian Civil War. In advanced economies the prosperity reached middle class households and many in the working class with radio, automobiles, telephones, and electric lighting and appliances. There was unprecedented industrial growth, accelerated consumer demand and aspirations, and significant changes in lifestyle and culture. The media began to focus on celebrities, especially sports heroes and movie stars. Major cities built large sports stadiums for the fans, in addition to palatial cinemas.

The timing varied across nations; in most countries it started in 1929 and lasted until the late 1930s. It was the longest, deepest, and most widespread depression of the 20th century. The depression originated in the United States and became worldwide news with the stock market crash of 29 October 1929 (known as Black Tuesday). Between 1929 and 1932, worldwide GDP fell by an estimated 15%. By comparison, worldwide GDP fell by less than 1% from 2008 to 2009 during the Great Recession. Some economies started to recover by the mid-1930s. However, in many countries, the negative effects of the Great Depression lasted until the beginning of World War II. The Great Depression had devastating effects in countries both rich and poor. Personal income, tax revenue, profits, and prices dropped, while international trade plunged by more than 50%. Unemployment in the United States rose to 25% and in some countries rose as high as 33%. Prices fell sharply, especially for mining and agricultural commodities. Business profits fell sharply as well, with a sharp reduction in new business starts. Cities all around the world were hit hard, especially those dependent on heavy industry.
