September 29 in History

Henry Robinson opened his Office of Addresses and Encounters on Threadneedle Street in London, creating the first historically documented service for matching people seeking companionship. The venture applied a commercial registry model to personal relationships, anticipating by three and a half centuries the matchmaking industry that would eventually evolve into modern online dating platforms.

Pompey paraded captured kings, gold, and a fleet of pirate ships through Rome to mark his third triumph on his forty-fifth birthday. This spectacle cemented his reputation as Rome's greatest general while inflaming political rivals who feared his unchecked power would topple the Republic.

Pompey arranged his third Roman triumph to land exactly on his 45th birthday — a scheduling flex that was entirely intentional and entirely him. He paraded the spoils of campaigns against pirates and Mithridates through Rome: 324 captured ships, conquered kings represented in chains, placards listing 900 cities he'd taken. The celebration lasted two days. He was so popular at that moment that he could've done almost anything. He chose to disband his army, walk back into civilian life, and trust the Senate. That trust would eventually cost him everything.

Frederick II kept promising to go on Crusade. He promised in 1215, again in 1220, again in 1227 — and kept not going. When he finally sailed in 1227 and turned back sick, Pope Gregory IX had had enough and excommunicated him. Then Frederick did something no one expected: he went on Crusade anyway, while still excommunicated. And he succeeded — negotiating a treaty that returned Jerusalem to Christian control without a single battle. The Pope was furious. Frederick had just won the Crusade the Church said he was too sinful to lead.

King Henry III forced Llywelyn ap Gruffudd to accept the title of Prince of Wales only as his feudal vassal in the Treaty of Montgomery. This arrangement granted Llywelyn temporary legitimacy over Welsh territories while confirming English royal authority, a fragile peace that collapsed just two years later when war erupted again between the realms.

Anglo-Breton forces crush the Franco-Breton army at Auray, shattering Charles de Blois's claim to the Duchy of Brittany and securing John IV's rule. This decisive victory ends the decade-long War of the Breton Succession, compelling France to accept English influence in the region for a generation while solidifying the Montfort dynasty's hold on the duchy.

Protestant insurgents in Nîmes dragged Catholic priests from their homes and executed them on September 29, 1567, during the French War of Religion. This brutal slaughter, known as the Michelade, shattered any remaining hope for peaceful coexistence between the factions and escalated the conflict into a cycle of retaliatory violence that deepened the religious divide across France.

Cossack troops slaughtered roughly 800 civilians overnight in Hailuoto, turning a localized rebellion into a massacre that shattered any hope of peaceful coexistence between the Tsardom of Russia and the Finnish population. This brutal display of force cemented Russian dominance in the region while leaving deep scars that fueled decades of local resistance against imperial rule.

Johann Sebastian Bach conducts the premiere of his cantata Herr Gott, dich loben alle wir to honor Archangel Michael, weaving Paul Eber's twelve-stanza hymn into a rich musical mix. This performance solidified the work as a cornerstone of the Lutheran liturgical calendar, ensuring its enduring presence in church services for centuries.

The first standing army the United States ever established — authorized in September 1789 — had a strength of about 840 men. That was it. The whole thing. The founding generation was deeply suspicious of permanent armies; they'd seen what a standing force could do in the hands of a crown. So Congress debated endlessly before agreeing to just a few hundred soldiers, mainly to man frontier forts. George Washington, who'd commanded tens of thousands, now nominally led a force smaller than some modern-day police departments.

When the Metropolitan Police launched in 1829, Londoners hated them. Not inconvenience-hated — genuinely, violently hated. The first officers weren't allowed to carry weapons and were routinely attacked in the streets. Home Secretary Robert Peel, who created the force, had the recruits wear civilian-style blue coats specifically to avoid looking like soldiers, because the public feared a military police state. The force was called 'Peelers' and 'Bobbies' — both nicknames for Peel — as insults first. Somewhere along the way, 'Bobby' stopped being a slur.
