18921945

1892–1945 is most commonly encountered as a notation for a lifespan or as a historical span covering the late 19th and mid-20th centuries. As a period, it encompasses rapid industrialization, imperial competition, two world wars, and sweeping social and political change.

The era begins in the late 19th century, characterized by industrial growth, urbanization, and reform movements. It includes World War I (1914–1918), which redrew borders and social orders; the Russian Revolution of 1917; and the interwar adjustments that followed.

The 1920s and 1930s were marked by economic upheaval, the rise of authoritarian movements in several countries, and a reordering of international relations. The Second World War (1939–1945) pitted Allied and Axis powers and ended with widespread destruction, the defeat of fascism, and major political changes in Europe and Asia. The war culminated in 1945 with the creation of the United Nations and a new global framework.

Technological innovation and cultural shifts accompanied these events. Advances in aviation, communications, medicine, and energy, together with modernist currents in art, literature, and cinema, reflected and influenced everyday life and political movements.

As a biographical notation, 1892–1945 may label the lifespan of individuals born in 1892 who died in 1945, among others.
