1991 felt like a hinge year. The Cold War gave way to a new geopolitical map, the Gulf War unfolded on live television, and the World Wide Web stepped into public view. Democracies stirred, borders shifted, a volcano dimmed skies, and pop culture found a louder, global voice.
Global Overview: Why 1991 Mattered
USSR dissolves: December ends the Soviet Union; 15 states emerge and a superpower era closes.
Gulf War: Air campaign starts Jan 17; a ~100-hour ground offensive (Feb 24–28) liberates Kuwait.
The Web opens: Tim Berners-Lee’s project leaves the lab and invites the public into hyperlinked space.
Nature’s shock: Mount Pinatubo erupts (June 15), sending ash high into the atmosphere and cooling temps.
In one year, maps, markets, and media all changed course. If the late ’80s loosened the Cold War, 1991 cut the knot.

Conflicts & Crises
