19151973

19151973 refers to either the lifespan of individuals born in 1915 who died in 1973, or to the historical span from 1915 through 1973. As a lifespan, it covers much of the mid‑20th century, a period of rapid geopolitical, social, and technological change.

Geopolitically, the interval begins in the final years of World War I, followed by the war’s aftermath and the redrawing of borders in Europe and the Middle East. The interwar years saw economic volatility and political upheaval, while World War II (1939–1945) reshaped nations and established the United States and the Soviet Union as superpowers. The ensuing Cold War framed international relations for decades, and the era witnessed widespread decolonization, new nation-states, and recurring regional conflicts.

In science and technology, this period includes major advances such as the mass diffusion of antibiotics, the invention and expansion of computing, the development of the transistor, and space exploration highlighted by the Moon landing in 1969. Aviation, telecommunications, and medical science also progressed rapidly, altering everyday life and global connectivity. Culturally, the 1960s and early 1970s saw significant social change, with civil rights movements, shifts in gender roles, and evolving media landscapes influencing politics and daily life.

The year 1973 marks a turning point with the oil crisis and related economic and geopolitical repercussions, signaling a transition to new economic challenges and energy policies that would shape subsequent decades.
