18871933

1887–1933 denotes a historical span that covers the final decades of the 19th century and the early decades of the 20th, a period of rapid industrial growth, geopolitical upheaval, and cultural transformation. In politics, it includes the height of imperial systems, the outbreak of World War I, the Russian Revolution, and the reordering of international affairs after the war. The Versailles settlement and the formation of international bodies set the stage for the interwar era, during which many nations grappled with modernization, nationalism, and economic volatility.

Economically, this period saw the acceleration of mass production, urbanization, and new financial systems, followed by the onset of the Great Depression in the late 1920s, which deepened social and political strains in many countries. Social changes included shifts in labor relations, women's rights, and education, alongside rising popular culture in cities around the world.

Culturally and scientifically, the era was marked by modernist experimentation in literature, art, and architecture; the growth of cinema and radio; and advances in science and technology, including groundbreaking developments in physics and medicine. Aviation and communications technologies rapidly reduced distances and connected distant regions.

By 1933, the interwar order faced significant stress; economic hardship, political radicalism, and the consolidation or collapse of regimes would shape trajectories for the rest of the decade. The 1887–1933 span thus summarizes a transition from 19th-century assumptions to a new, contested global architecture that would define much of the 20th century.
