18541925

18541925 is a date notation commonly written as 1854–1925. It serves as a shorthand for a range that can denote either a life span or a historical period. When used to indicate a person’s life dates, 1854–1925 identifies someone born in 1854 and who died in 1925. In biography and genealogy, such a single dash is standard and allows readers to place the subject in a historical timeline.

As a historical period, 1854–1925 describes roughly the years from mid‑19th century through the early 20th century. This span covers rapid industrialization in many regions, the expansion of railways and telecommunication networks, and the rise of nation‑states and modern bureaucratic states. It includes the late Victorian era, the Progressive Era in the United States, and the broader age of imperialism. The period also encompasses World War I (1914–1918), the Russian Revolution of 1917, and the postwar realignments that reshaped borders and politics. The end of the period, around 1925, witnesses the early stirrings of modernist movements in art and literature and the beginnings of social and political reforms that would continue into the interwar years.

Usage notes: If the subject is a biography, the context will determine whether 1854–1925 refers to life dates or to a defined period of activity. See also lists of people born in 1854 or died in 1925 for related cross‑references.
