Since the end of the 20th century, the economic strength during the 1920s has drawn close comparison with the 1950s and 1990s, especially in the United States of America. These three decades are regarded as periods of economic prosperity, which lasted throughout nearly each entire decade. Each of the three decades followed a tremendous event that occurred in the previous decade (World War I and Spanish flu in the 1910s, World War II in the 1940s, and the end of the Cold War in the late 1980s). The 1920s marked the first time in the United States that the population in the cities surpassed the population of rural areas. This was due to rapid urbanization starting in the 1920s.
However, not all countries enjoyed this prosperity. The Weimar Republic, like many other European countries, had to face a severe economic downturn in the opening years of the decade, because of the enormous debt caused by the war as well as the Treaty of Versailles. Such a crisis would culminate with a devaluation of the Mark in 1923, eventually leading to severe economic problems and, in the long term, favour the rise of the Nazi Party.
Siegmund "Zishe" Breitbart (1893–1925), shown here pulling a heavy weight using only his teeth, was a Polishstrongman and circus performer who was known as the "Strongest Man in the World" during the 1920s. He was widely popular in both Europe and the U.S., but died at the age of 32 after an accident during a performance.
