December 17 in History

Rome's newest festival promised something radical: slaves ate first. For one December day, masters served their own household workers at banquet tables, roles reversed, social order suspended. The Senate had approved it to honor Saturn, god of agriculture and time before hierarchy existed. Participants wore soft caps instead of togas. Gambling was legal. You could say anything to anyone without punishment. The experiment worked so well it expanded to seven days, then survived Rome itself—nearly every culture that followed invented some version of the same idea. What started as controlled chaos became the template for every holiday that lets people briefly pretend the rules don't apply.

The garrison commander took Totila's gold and opened the Asinarian Gate at midnight. What followed wasn't a massacre — it was something stranger. Totila's Ostrogoths walked through Rome's streets and found a population already starved to near-extinction by their own Byzantine defenders. The city that once held a million people now sheltered maybe 500. Totila ordered no killings. He burned sections of the walls instead, then left. Rome, unconquered by foreign armies for 800 years, fell not to force but to a bribe. And the Gothic king who bought it didn't even want to stay.

The three Myinsaing brothers topple King Kyawswa of Pagan on December 17, 1297, shattering central authority across the Irrawaddy Valley. This coup fractures the once-unified kingdom into warring principalities, ending nearly two centuries of centralized rule and triggering decades of regional fragmentation that reshape Burmese politics forever.

Margaret II and her son William I signed a peace treaty on December 17, 1354, to end decades of civil strife known as the Hook and Cod wars. This agreement finally halted the violent factional fighting that had torn Holland and Hainaut apart, allowing both regions to stabilize their economies and rebuild their shattered towns under unified rule.

Drake left Plymouth with five ships and 164 men on what Elizabeth called a trading voyage. She lied. Her real orders: raid Spanish colonies along the Pacific coast and claim new lands for England. Spain controlled that ocean completely—no English ship had ever entered it. Drake's crew didn't know the true mission. Neither did Spain, which made peace with England that same year. By the time Spanish authorities realized an English pirate was loose in their private sea, Drake had already captured a treasure ship carrying 80 pounds of gold and 26 tons of silver. Only one of his five ships made it home. But that one carried enough stolen wealth to fund the English treasury for seven years.

Ernest of Bavaria's cannons blasted Godesberg Castle for three weeks straight. Inside, Gebhard Truchsess von Waldburg — the prince-archbishop who'd converted to Protestantism and married his mistress — watched his walls crumble. He'd sparked the Cologne War by refusing to give up his throne after his conversion. When the fortress fell, his men were slaughtered or captured. Gebhard escaped and spent the rest of his life in exile, dying broke in Strasbourg. Ernest took the archbishopric and kept it Catholic for another two centuries. One marriage, one war, one religion locked in place.

Bolívar stood in Angostura — a river town Spain couldn't hold — and declared something that didn't exist yet: Gran Colombia. Not just Venezuela. Not a single colony freed. He announced a republic spanning modern Venezuela, Colombia, Ecuador, and Panama before most of it was even liberated. The wars would drag on another four years. But the declaration worked backward: it created the nation first, then dared his army to make it real. They did. Within a decade, Bolívar's imagined country controlled two million square miles. Then ego and geography tore it apart — the republic fractured into four countries by 1831, twelve years after he conjured it into existence.

Grant believed Jewish merchants were smuggling cotton to the North, enriching themselves while his army struggled for supplies. He gave families 24 hours to leave — women, children, elderly, anyone with Jewish heritage. Some had lived there for generations. Some had sons fighting for the Union. Didn't matter. Lincoln revoked the order three weeks later, but by then entire communities had already scattered. Grant never quite apologized. Thirty years later, when he ran for president, Jewish voters remembered — and forgave him anyway. He'd learned. What stuck wasn't the expulsion order itself, but how fast collective punishment can become official policy when someone needs a scapegoat.

The first building in North America with artificial ice — real hockey in September, real figure skating in July — burned to the ground in 12 minutes. Schenley Park Casino had opened just two years earlier with a radical brine-cooled floor system that cost $100,000, more than most entire arenas at the time. Pittsburgh's elite skated there in summer tuxedos while outside temperatures hit 90 degrees. The fire started in the chemical room housing the ice-making equipment. By the time firefighters arrived, the wooden structure was already collapsing. The technology survived: within a decade, 20 North American cities had copied the system.

Orville Wright steers the Wright Flyer into a 12-second hop that shatters centuries of human limitation. This feat forces engineers to abandon rigid gliders for powered propulsion, launching an era where global travel shrinks from months to hours and reshapes warfare, commerce, and culture forever.

Up to 1,000 residents of Darwin marched on Government House to demand the removal of the Northern Territory administrator, protesting wartime labor restrictions and the government's heavy-handed treatment of returned soldiers. The rebellion forced the administrator's recall and became the largest civil disturbance in Australian outback history.
