18691964

1869–1964 is a year-range that may refer to a historical period, a biographical lifespan, or any dataset bounded by those years. When used to describe a period, it encompasses late 19th-century transformation and much of the mid-20th century, capturing shifts in industry, politics, culture, and technology.

Within this span, notable milestones include the completion of the First Transcontinental Railroad in 1869, the onset of World War I (1914–1918), the Russian Revolution of 1917, the global upheavals of the Great Depression in the 1930s, and World War II (1939–1945). The postwar era saw decolonization, the establishment of international institutions, and the beginnings of the Cold War. The year 1964 itself saw significant events such as the signing of the Civil Rights Act in the United States and the Tokyo Summer Olympics.

Technological and cultural developments during 1869–1964 included rapid electrification, the spread of the telephone and automobile ownership, advances in aviation and cinema, the rise of radio and early computing, and the initiation of space exploration with later milestones in the 1950s and 1960s.

In bibliographic and biographical contexts, the designation can describe individuals who lived from 1869 to 1964, or works created within that span, making it a common shorthand in historical databases and encyclopedic references.
