Post-modernity spans 1945 to 2016 C.E., an era defined by rapid technological acceleration, decolonization, the rise of the internet, and expanding civil rights. This archive collects milestones in science, medicine, governance, and culture from those seven decades of sweeping human progress.
Uzbekistan’s independence arrived on August 31, 1991, when the Uzbek Soviet Socialist Republic stepped out from seven decades of Soviet rule to become one of 15 nations born from the USSR’s collapse. The declaration came days after a failed Moscow coup cracked central authority. For a land shaped by Samarkand, Bukhara, and Silk Road trade, it was a return of an old name to its own people.
The World Wide Web opened to the public on 23 August 1991, when Tim Berners-Lee released his creation beyond CERN’s walls to anyone with a network connection. There was no fanfare — just an open door. Two years later, roughly 50 websites existed, a quiet start to one of humanity’s great shared experiments.
The Bicesse Accords, signed in Lisbon on May 31, 1991, offered Angola its first real shot at peace after 16 years of civil war. Mediated by Portugal with U.S. and Soviet observers, the agreement laid out a ceasefire, UN-monitored elections, and a plan to merge rival armies. Though fragile, it reshaped how Angola’s conflict would eventually end.
Offshore wind began quietly in 1991, when Danish workers planted 11 small turbines in the shallow waters off Vindeby, on the island of Lolland. Each one produced just 450 kilowatts, powering a few thousand homes and proving turbines could survive the sea. It was the first offshore wind farm ever built — a modest experiment that opened a door.
Ukrainian independence arrived on August 24, 1991, when parliament in Kyiv voted to leave the Soviet Union just one day after a failed coup weakened Moscow. Months later, more than 90 percent of voters confirmed the choice, with majorities in every region. It was a quiet ending to an empire, and a long-awaited return for a nation with ancient roots.
The Convention on the Rights of the Child entered into force on 2 September 1990, making children rights-holders under international law for the first time. Drafted at the UN and now ratified by 196 countries, it remains the most widely adopted human rights treaty ever — a quiet turning point in how the world sees childhood itself.
The Hubble Space Telescope launched aboard Shuttle Discovery on April 24, 1990, carrying a 2.4-meter mirror above Earth’s distorting atmosphere. After a famously blurry start, astronauts installed corrective optics in 1993, and Hubble went on to contribute to more than 19,000 peer-reviewed papers — making distant galaxies feel, for the first time, genuinely knowable.
Finland’s carbon tax, introduced in January 1990, was the first of its kind anywhere in the world. It started modestly at about €1.12 per tonne of CO₂, more a proof of concept than a heavy lever. Sweden followed the next year, and the idea gradually reshaped how governments think about pricing pollution.
The Simpsons premiered on Fox on December 17, 1989, bringing a yellow-skinned Springfield family to American primetime for the first time. Matt Groening had sketched Homer, Marge, Bart, Lisa, and Maggie in a waiting room minutes before his pitch meeting. The half-hour series opened a door animated comedy for adults has walked through ever since.
The Velvet Revolution swept through Czechoslovakia in November 1989, ending 41 years of Communist rule in just 11 days without a shot fired. After riot police beat student marchers in Prague on November 17, crowds swelled to half a million within days. Playwright Václav Havel was president by year’s end.
