Powhatan Uprising

Opechancanough, leader of the Powhatan Confederacy, orchestrated a surprise assault on English settlements along the James River, killing about a quarter of the colony's population in hours. The attack, a response to years of land encroachment and broken agreements, nearly destroyed the Jamestown colony and hardened English attitudes toward the Powhatan people for a generation.

The Stamp Act

The British Parliament passed the Stamp Act, requiring colonists to pay a tax on virtually every piece of printed paper they used, from newspapers to playing cards. Colonists, who had no representation in Parliament, erupted in protest under the banner "no taxation without representation." The backlash forced repeal within a year but set the colonies on an irreversible path toward revolution.

Denmark-Norway Bans Slave Trade

King Christian VII's government issued a decree banning Danish participation in the transatlantic slave trade, to take effect in 1803, making Denmark-Norway the first European nation to legislate against the trade. The law stopped new slave shipments but did not free those already enslaved in Danish colonies like the Virgin Islands, where slavery itself persisted for decades more.

The Spanish National Assembly decreed the abolition of slavery in Puerto Rico, freeing an estimated 30,000 enslaved people on the island. Enslaved individuals were required to work for their former masters for three more years under contract, a compromise that softened resistance from plantation owners while still marking a landmark moment in the Caribbean's long struggle against slavery.

Nixon Discusses Watergate Cover-Up

In a recorded Oval Office conversation, Richard Nixon discussed paying hush money to E. Howard Hunt and other Watergate burglars to keep them silent, remarking that cost was no obstacle. The tape, later released during the impeachment investigation, provided some of the most damning direct evidence of Nixon's personal involvement in obstructing justice.

Apple Unveils the Macintosh 512K

Apple launched the Macintosh 512K, nicknamed the "Fat Mac," boosting RAM from 128 kilobytes to 512 kilobytes. The upgrade addressed one of the loudest complaints about the original 1984 Macintosh, that its memory was too limited for serious software, and helped keep Apple's graphical-interface vision alive during a difficult early period for the machine.

Russia's Soyuz MS-12 spacecraft launched from Baikonur Cosmodrome carrying a three-person crew to the International Space Station, docking just over six hours later. The flight marked a return to orbit for Nick Hague, who had survived a dramatic launch abort the previous October, and began Christina Koch's record-setting extended mission aboard the station.
