18631933

18631933 is a compact numeric string that is commonly used to denote the lifespan of a person when birth and death years are written without separators. In standard biographical notation, the range is typically shown with an en dash as 1863–1933, indicating birth in 1863 and death in 1933. Without punctuation, the string can appear in data fields, catalogs, or filenames where separators are omitted, potentially requiring context to disambiguate.

As a historical interval, 1863 to 1933 encompasses a period of substantial global change. The late 19th century featured rapid industrialization, urbanization, and imperial expansion. The early 20th century brought World War I (1914–1918), the Russian Revolution of 1917, and the redrawing of international borders. The 1920s saw economic fluctuations and cultural shifts in many regions, while the 1929 stock market crash ushered in the Great Depression, which persisted into the early 1930s. By 1933, political and economic upheavals had contributed to the rise of new regimes and significant policy experimentation in several countries, including the United States and parts of Europe.

There is no single individual or organization universally associated with the exact string 18631933; it is primarily used to indicate a birth–death range or, more broadly, a time span. See also 1863, 1933, lifespan notation, and year-range conventions.
