May 28 in History

The sun went dark mid-battle, and both armies dropped their weapons. Thales of Miletus had predicted it—the first recorded solar eclipse forecast in history, May 28, 585 BCE. Alyattes of Lydia and Cyaxares of Media had been fighting for control of Anatolia for six years. Their soldiers watched the sky swallow itself and decided the gods had spoken. They signed a treaty that same day. The Halys River became the border. But here's what matters: Thales proved you could calculate the cosmos. Divine intervention looked a lot like math, and everyone knew it now.

Li Shimin had 3,500 cavalry. Dou Jiande brought 100,000 men to Hulao Pass in Henan. The numbers didn't matter. Shimin's father had just founded the Tang Dynasty, but half of China wasn't buying it yet. The 22-year-old prince charged anyway, smashing through Dou's center in a single day of fighting. Dou himself got captured. His entire army dissolved. And just like that, the civil war that could've torn China into a dozen kingdoms ended instead with three centuries of Tang rule. Sometimes history turns on one reckless charge by one emperor's son.

They murdered the inquisitors in their sleep. William Arnaud and eleven companions were hunting heretics in Languedoc when Cathars stormed their lodgings at Avignonet on May 28th. Axes and swords. No survivors. Count Raymond VII of Toulouse almost certainly knew it was coming—possibly even gave the nod. The killings bought the Cathars exactly three years. By 1245, the Pope had declared a full crusade against Raymond, and by 1255, organized Catharism was essentially extinct in southern France. Turns out martyring a dozen inquisitors is excellent fuel for the very persecution you're trying to stop.

They called it "everlasting." James IV of Scotland married Margaret Tudor in 1503, her father Henry VII footing the bill for a wedding that cost more than Scotland's annual revenue. The papal bull from Alexander VI—yes, that Borgia pope—blessed the union meant to end centuries of bloodshed along the border. Ten years later, James lay dead at Flodden Field, cut down by his wife's brother's army. The "Everlasting Peace" lasted exactly a decade. Though Margaret's great-grandson would eventually unite both crowns, just not the way anyone imagined at the altar.

Cranmer didn't even have the authority yet—his papal bulls confirming him as Archbishop wouldn't arrive for another two months. But Henry needed this marriage legal *now*. Anne was already four months pregnant, and a bastard heir solved nothing. So on May 23rd, Cranmer held a secret court at Dunstable Priory, ten miles from where Catherine of Aragon was staying, and declared Henry's first marriage invalid. Five days later, he ruled Anne's marriage good. The Church of England's first official act was retroactive legitimization of a king who'd already made up his mind.

The supply lists alone took three months to compile: 130 ships needed 300,000 pounds of biscuits, 600,000 pounds of salt pork, and fourteen million gallons of wine. King Philip II's "Invincible Armada" began limping out of Lisbon on May 20, 1588—so many vessels that it took ten days for them all to clear port. Each day's delay meant more spoiled food, more sick sailors, more doubt creeping through the decks. The man commanding this floating city, the Duke of Medina Sidonia, had begged Philip not to give him the job. He got seasick.

Louis Delgrès and his men wrote "Live Free or Die" on their final proclamation to the people of Guadeloupe. Napoleon had sent 15,000 troops to restore slavery across the French Caribbean after briefly abolishing it. The rebels held Mahabou fortress for three weeks against impossible odds. When the walls fell on May 28, 1802, Delgrès detonated the powder magazine. Four hundred chose the explosion. The blast was heard for miles. France got Guadeloupe back. Just not the people who knew its mountains best.

Jackson owned more than 150 enslaved people when he signed the law that would remove 60,000 Native Americans from their ancestral lands. The act forced Cherokee, Creek, Choctaw, Chickasaw, and Seminole nations westward on routes that killed roughly one in four travelers. Starvation, disease, winter exposure. The Cherokee called their 1838 march the Trail Where They Cried—we know it as the Trail of Tears. Georgia had found gold on Cherokee land two years before the law passed. Sometimes legislation isn't about expansion. It's about who's standing on something valuable.

The regiment marched through Boston streets lined with 20,000 people—more than had watched any military parade in the city's history. Most came to see if Black men could march in formation. They could. The 54th's 1,000 soldiers had turned away twice as many volunteers, and some had walked from as far as Ohio to enlist. Two of Frederick Douglass's sons marched in the ranks. Within three months, they'd assault Fort Wagner in South Carolina, losing nearly half their men in a charge that proved nothing about courage—only that some people needed proof.
