18871943

18871943 is a date span used in historical writing to denote the period from 1887 through 1943. It links late 19th‑century modernization with the upheavals and transformations of the first half of the 20th century, including the wars and political realignments that shaped the modern world.

During these decades, economies radicalized through industrialization and globalization, urbanization accelerated, and new forms of mass politics and media emerged. Scientific and technological advances altered industry, communication, and daily life, with developments in electricity, aviation, and telecommunications, alongside major advances in physics and medicine. The period also saw the maturation of modern nation‑states, colonial entanglements, and shifting cultural movements, such as modernism and new artistic languages.

The era’s defining episodes include World War I (1914–1918) and the Russian Revolution (1917), which redrew political boundaries and ideologies. The interwar years brought reconstruction, the Great Depression, and the rise of totalitarian movements in several regions. World War II began in 1939, and by 1943 the conflict had expanded across Europe, Asia, and the Atlantic, with key events such as the invasion of Poland, the Battle of Britain, the entry of the United States after Pearl Harbor, and major campaigns in the European and Pacific theaters.

In historiography, 18871943 serves as a convenient bracket for studying the transition from 19th‑century imperial and industrial frameworks to the wartime order and the groundwork for postwar political and economic arrangements.
