The 1920s was a decade sometimes referred to as the "Jazz Age" or the "Roaring Twenties," usually applied to America. In Europe the decade is sometimes referred to as the Golden Twenties (see 1920s Berlin).

Events and Trends

Since the closing of the 20th Century, the 1920s has drawn close associations with the 1950s and 1990s, especially in the United States. The three decades are regarded as periods of economic prosperity, which lasted throughout almost the entire decade following 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). In the United States, this decade was known as the Roaring Twenties.

Despite the comparisons, however, there were a number of differences. Firstly, Weimar Republic Germany, like many other European countries, had to face a severe economic downturn in the opening years of the decade, due to the enormous debt caused by the war as well as the one-sided Treaty of Versailles. Such a crisis would culminate with a devaluation of the Mark in 1923, eventually leading to severe economic problems and the rise of the Nazis.

Second, the decade was characterized by the rise of radical political movements, especially in regions that were once part of empires. Communism began attracting large numbers of followers following the success of the October Revolution and the Bolsheviks' determination to win the subsequent Russian Civil War. The Bolsheviks would eventually adopt semi-capitalist policies-- New Economic Policy-- from 1921 to 1928. The 1920s also experienced the rise of the far-right in Europe and elsewhere, starting with Fascism in the world as an antidote to Communism.

The Stock Market collapsed during October 1929 (see Black Tuesday) and drew a line under prosperous 1920s.
