August 22 in History

King Baldwin III's coalition of Templars and Hospitallers seized the fortress of Ascalon from Fatimid Egypt, finally removing the last major Muslim stronghold threatening Jerusalem's southern flank. This surrender ended a century-long siege and secured the Kingdom of Jerusalem's borders, allowing the Crusader states to focus their resources on internal consolidation rather than constant border warfare.

Richard III falls dead on Bosworth Field, shattering three centuries of Plantagenet rule and compelling Henry VII to claim the English crown. This violent shift ends the Wars of the Roses, allowing the Tudor dynasty to consolidate power and reshape the nation's religious and political future for a hundred years.

Violent mobs stormed Frankfurt's Judengasse, looting homes and driving the expulsion of its entire Jewish population in August 1614. This brutal pogrom shattered the city's fragile economic stability and compelled authorities to reimpose strict martial law for years to restore order.

Eight British transport ships from Admiral Hovenden Walker's Quebec Expedition wrecked on rocks at the mouth of the Saint Lawrence River, drowning nearly 900 soldiers and sailors. The disaster aborted Britain's most ambitious attempt to capture French Canada, delaying the conquest by almost 50 years.

James Cook landed on Possession Island off the tip of Cape York and formally claimed the entire east coast of Australia — which he named New South Wales — for King George III. The claim, made with no consultation of the Aboriginal peoples who had inhabited the continent for 65,000 years, laid the legal foundation for British colonization.

British forces under Barry St. Leger abandoned the siege of Fort Stanwix after exaggerated rumors of a massive Continental Army relief column panicked their Iroquois allies into deserting. The withdrawal wrecked the British plan to isolate New England and contributed directly to General Burgoyne's devastating defeat at Saratoga two months later.

Over a thousand French soldiers landed at Kilcummin harbour in County Mayo to support Wolfe Tone's United Irishmen rebellion against British rule. The expeditionary force initially routed local British militia but was eventually surrounded and forced to surrender, ending the last foreign military invasion of the British Isles.

Nat Turner planned his rebellion for months. He was an enslaved preacher who believed he'd received a divine sign to act. Just after midnight on August 22, 1831, he and a small group of men moved through Southampton County, Virginia, killing every white person they could reach. By morning, over 50 were dead. Virginia militia put down the rebellion within days. Turner hid for two months before being captured. He was tried, convicted, and hanged in November. The retaliation killed hundreds of Black Southerners — many of whom had nothing to do with the uprising.
