The 1920s (pronounced "nineteen-twenties" often shortened to the "20s" or the "Twenties") was a decade that began on January 1, 1920, and ended on December 31, 1929. In 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 Twenties" because of the economic boom following World War I (1914-1918). French speakers refer to the period as the "Années folles" ("Crazy Years"), emphasizing the era's social, artistic, and cultural dynamism.
The 1920s saw foreign oil companies begin operations in Venezuela, which became the world's second-largest oil-producing nation. 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. In the Soviet Union the New Economic Policy was created by the Bolsheviks in 1921, to be replaced by the first five-year plan in 1928. The 1920s saw the rise of radical political movements, with the Red Army triumphing against White movement forces in the Russian Civil War, and the emergence of far right political movements in Europe. In 1922, the fascist leader Benito Mussolini seized power in Italy. Economic problems contributed to the emergence of dictators in Eastern Europe to include Józef Piłsudski in Poland, and Peter and Alexander Karađorđević in Yugoslavia. First-wave feminism saw progress, with women gaining the right to vote in the United States (1920), Ireland (1921) and with suffrage being expanded in Britain to all women over 21 years old (1928).
In Turkey, nationalist forces defeated Greece, France, Armenia and Britain in the Turkish War of Independence, leading to the Treaty of Lausanne (July 1923), a treaty more favorable to Turkey than the earlier proposed Treaty of Sèvres. The war also led to the abolition of the Ottoman Caliphate. Nationalist revolts also occurred in Ireland (1919–1921) and Syria (1925–1927). Under Mussolini, Italy pursued a more aggressive foreign policy, leading to the Second Italo-Senussi War in Libya. In 1927, China erupted into a civil war between the Kuomintang (KMT)-led government of the Republic of China (ROC) and forces of the Chinese Communist Party (CCP). Civil wars also occurred in Paraguay (1922–1923), Ireland (1922–1923), Honduras (1924), Nicaragua (1926–1927), and Afghanistan (1928–1929). Saudi forces conquered Jabal Shammar and subsequently, Hejaz.
A severe famine occurred in Russia in 1921–1922 due to the combined effects of economic disturbance because of the Russian Revolution and the Russian Civil War, exacerbated by rail systems that could not distribute food efficiently, leading to 5 million deaths. Another severe famine occurred in China in 1928–1930, leading to 6 million deaths. The Spanish flu (1918–1920) and the 1918–1922 Russia typhus epidemic, which had begun in the previous decade, caused 25–50 million and 2–3 million deaths respectively. Major natural disasters of this decade include the 1920 Haiyuan earthquake (258,707~273,407 deaths), the 1922 Swatow typhoon (50,000–100,000 deaths), the 1923 Great Kantō earthquake (105,385–142,800 deaths), and the 1927 Gulang earthquake (40,912 deaths).
Silent films were popular in this decade, with the 1925 American silent epic adventure-drama film Ben-Hur: A Tale of the Christ being the highest-grossing film of this decade, grossing $9,386,000 worldwide. Other high-grossing films of this decade include The Big Parade and The Singing Fool. Sinclair Lewis was a popular author in the 1920s, with 2 of his books, Main Street and Elmer Gantry, becoming best-selling books in the United States in 1921 and 1927 respectively. Other best-selling books of this decade include All Quiet on the Western Front and The Private Life of Helen of Troy. Songs of this decade include "Are You Lonesome Tonight?" and "Stardust".
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 finger wave or 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 Fascist regime pursues an aggressive expansionist agenda in Europe such as by raiding the Greek island of Corfu in 1923, pressuring Albania to submit to becoming a de facto Italian protectorate in the mid-1920s, and holding territorial aims on the region of Dalmatia in Yugoslavia.
- In Germany, the Weimar Republic suffers from economic crisis in the early 1920s and hyperinflation of currency in 1923. From 1923 to 1925 the Occupation of the Ruhr takes place. The Ruhr was an industrial region of Germany taken over by the military forces of the French Third Republic and Belgium, in response to the failure of the Weimar Republic under Chancellor Wilhelm Cuno to keep paying the World War I reparations. The recently formed fringe National Socialist German Workers' Party (a.k.a.

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 (such as short skirts or trousers). 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 continued to characterize fashion until the worldwide depression worsened in 1931.

- Way Down East: p. 52. "D.W. Griffith's Way Down East (1920) was projected to return rentals of $4,000,000 on an $800,000 negative. This figure was based on the amounts earned from its roadshow run, coupled with its playoff in the rest of the country's theaters. Griffith had originally placed the potential film rental at $3,000,000 but, because of the success of the various roadshows that were running the $4,000,000 total was expected. The film showed a profit of $615,736 after just 23 weeks of release on a gross of $2,179,613."
- What Price Glory?: p. 112. "What Price Glory hit the jackpot with massive world rentals of $2,429,000, the highest figure in the history of the company. Since it was also the most expensive production of the year at $817,000 the profit was still a healthy $796,000..."
- Cavalcade: p. 170. "The actual cost of Cavalcade was $1,116,000 and it was most definitely not guaranteed a success. In fact, if its foreign grosses followed the usual 40 percent of domestic returns, the film would have lost money. In a turnaround, the foreign gross was almost double the $1,000,000 domestic take to reach total world rentals of $3,000,000 and Fox's largest profit of the year at $664,000."
- State Fair: p. 170. "State Fair did turn out to be a substantial hit with the help of Janet Gaynor boosting Will Rogers back to the level of money-making star. Its prestige engagements helped raked in a total $1,208,000 in domestic rentals. Surprisingly, in foreign countries unfamiliar with state fairs, it still earned a respectable $429,000. With its total rentals, the film ended up showing a $398,000 profit."
- Hall & Neale 2010, p. 53. "The Four Forsemen of the Apocalypse was to become Metro's most expensive production and one of the decade's biggest box-office hits. Its production costs have been estimated at "something between $600,000 and $800,000." Variety estimated its worldwide gross at $4 million in 1925 and at $5 million in 1944; in 1991, it estimated its cumulative domestic rentals at $3,800,000."

The negative cost was about $986,000, which did not include Fairbanks' own salary. Once the exploitation and release prints were taken into account, Robin Hood cost about $1,400,000—exceeding both Intolerance ($700,000) and the celebrated "million dollar movie" Foolish Wives.
