1920s


The 1920s was a decade of the Gregorian calendar that began on January 1, 1920, and ended on December 31, 1929. In North America, it is frequently referred to as the "Roaring Twenties" or the "Jazz Age", while in Europe the period is sometimes referred to as the "Golden Age Twenties" because of the economic boom following World War I. French speakers refer to the period as the "Années folles", emphasizing the era's social, artistic, and cultural dynamism.
The economic prosperity experienced by many countries during the 1920s was similar in nature to that experienced in the 1950s and 1990s. Each period of prosperity was the result of a paradigm shift in global affairs. These shifts in the 1920s, 1950s, and 1990s, occurred in part as the result of the conclusion of World War I and Spanish flu, World War II, and the Cold War, respectively.
The 1920s saw foreign oil companies begin operations throughout South America. Venezuela became the world's second largest oil producing nation.
In some countries the 1920s saw the rise of radical political movements, especially in regions that were once part of empires. Communism spread as a consequence of the October Revolution and the Bolsheviks' victory in the Russian Civil War. Fear of the spread of Communism led to the emergence of far right political movements and fascism in Europe. Economic problems contributed to the emergence of dictators in Eastern Europe and the Balkans, to include Józef Piłsudski in the Second Polish Republic, and Peter and Alexander Karađorđević in the Kingdom of Yugoslavia.
The devastating Wall Street Crash in October 1929 is generally viewed as a harbinger of the end of 1920s prosperity in North America and Europe.

Social history

The Roaring Twenties brought about several novel and highly visible social and cultural trends. These trends, made possible by sustained economic prosperity, were most visible in major cities like New York, Chicago, Paris, Berlin and London. "Normalcy" returned to politics in the wake of hyper-emotional patriotism during World War I, jazz blossomed, and Art Deco peaked. For women, knee-length skirts and dresses became socially acceptable, as did bobbed hair with a marcel wave. The women who pioneered these trends were frequently referred to as flappers.
The era saw the large-scale adoption of automobiles, telephones, motion pictures, radio and household electricity, as well as 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. Large baseball stadiums were built in major U.S. cities, in addition to palatial cinemas.
Most independent countries passed women's suffrage after 1918, especially as a reward for women's support of the war effort and endurance of its deaths and hardships.

The 1920s is the decade in which fashion entered the modern era. It was the decade in which women first abandoned the more restricting fashions of past years and began to wear more comfortable clothes. Men also abandoned highly formal daily attire and even began to wear athletic clothing for the first time. The suits men wear today are still based, for the most part, on those worn in the late 1920s. The 1920s are characterized by two distinct periods of fashion. In the early part of the decade, change was slow, as many were reluctant to adopt new styles. From 1925, the public passionately embraced the styles associated with the Roaring Twenties. These styles continue to characterize fashion until the worldwide depression worsened in 1931.
