18871961

18871961 is a sequence of calendar years that is commonly used in historical, biographical, and archival contexts to indicate a time span. Its interpretation depends on punctuation and context; with a dash, as in 1887–1961, it most often denotes a lifespan in biographical records, where 1887 is the birth year and 1961 is the death year.

As a period, the range 1887–1961 encompasses a broad swath of modern history. It covers the late 19th century, the turn of the 20th century, World War I, the interwar period, World War II, and the early years of the Cold War. The era witnessed rapid industrial and technological change, including electrification, the expansion of rail and urban infrastructure, advances in aviation and communications, and the spread of mass media. Political and social transformations were also pronounced, with imperial structures, revolutions, the rise of new states, and movements for social change and decolonization taking place across different regions.

In archival practice, 1887–1961 is used to identify the lifetime of individuals or the active years of organizations, movements, or cultural trends associated with those dates. It is a dating convention rather than a reference to a specific subject.

Limitations: without additional context, the notation does not specify a particular person, place, or entity. It serves as a concise label for a chronological interval that can denote biographical data, historical eras, or the span of activity for various subjects.
