The 1920s (pronounced “nineteen-twenties,” often shortened to the “20s”) 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 Pilsudski in Poland, and Peter and Alexander Karadordevic 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 Kanto 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.
