In the history of the 20th century, the interwar period (or interbellum) lasted from 11 November 1918 to 1 September 1939 (20 years, 9 months, 21 days) – from the end of World War I to the beginning of World War II. It was relatively short, yet featured many social, political, and economic changes throughout the world. Petroleum-based energy production and associated mechanisation led to the prosperous Roaring Twenties, a time of social and economic mobility for the middle class. Automobiles, electric lighting, radio, and more became common among populations in the first world. The era's indulgences were followed by the Great Depression, an unprecedented worldwide economic downturn that severely damaged many of the world's largest economies.
Politically, the era coincided with the rise of communism, starting in Russia with the October Revolution and Russian Civil War, at the end of World War I, and ended with the rise of fascism, particularly in Germany and Italy. China was in the midst of a half-century of instability and the Chinese Civil War between the Kuomintang and the Chinese Communist Party. The empires of Britain, France, and others faced challenges as imperialism was increasingly viewed negatively and independence movements emerged in many colonies; in Europe, after protracted low-level fighting most of Ireland became independent.
The Russian, Ottoman, Austro-Hungarian, and German Empires were dismantled, with the Ottoman territories and German colonies redistributed among the Allies, chiefly Britain and France. The western parts of the Russian Empire, Estonia, Finland, Latvia, Lithuania, and Poland became independent nations in their own right, and Bessarabia (now Moldova and parts of Ukraine) chose to reunify with Romania.
In Russia, the Bolsheviks managed to regain control of Belarus and Ukraine, Central Asia, and the Caucasus, forming the Soviet Union. In the Near East, Egypt and Iraq gained independence. During the Great Depression, countries in Latin America nationalised many foreign companies (most of which belonged to the United States) in a bid to strengthen their own economies. The territorial ambitions of the Soviets, Japanese, Italians, and Germans led to the expansion of their domains.
