Some sitcom episodes run longer than this. On August 27, 1896, Britain and the Sultanate of Zanzibar fought what’s now recognized as the shortest war in recorded history: 38 minutes, start to finish, cannon fire included. By the time anyone back in London would have heard it had started, it was already over.
And this isn’t an urban legend or a number rounded up to make a catchy headline: the timing is documented down to the minute, complete with a start time, a surrender time, and a sultan fleeing out the back door.
A “wrong” sultan in under a day
It all started with a succession London wasn’t happy about. On August 25, 1896, Sultan Hamad bin Thuwaini died — a comfortably pro-British ruler. Hours later, his cousin Khalid bin Barghash moved into the palace and declared himself sultan on his own, without asking Britain’s permission.
The trouble was that, under an 1886 treaty, Zanzibar was effectively a British protectorate, and any new sultan needed London’s approval before taking the throne. Khalid skipped that step entirely, gathered around 2,800 men, some artillery, and the sultanate’s single warship, and barricaded himself in the palace overlooking the harbor. Britain treated it, quite simply, as a coup.
38 minutes, on the clock
The British issued an ultimatum: surrender by 9:00 a.m. on August 27, or they’d open fire. Khalid didn’t back down — by most accounts, he assumed no one would actually dare. At 9:02, five Royal Navy warships anchored off the palace began shelling it.
The wooden palace didn’t last long: it caught fire and partially collapsed within minutes, the sultanate’s only warship was sunk almost immediately, and resistance crumbled fast. By 9:40, the guns had gone quiet. Thirty-eight minutes of war, total, according to History Today, which has documented the timeline of the conflict in the most detail.
The casualty count was wildly lopsided: an estimated 500 Zanzibari soldiers and civilians died, while the British side counted exactly one injured sailor. A blisteringly short war — but not remotely a symbolic one for the people inside that palace.
The escape that sealed the story
And Khalid? The moment he saw the palace coming down around him, he slipped out a back door and sprinted to the nearby German consulate. Since the British couldn’t storm foreign diplomatic ground, he was stuck there — technically free, but thoroughly cornered, with the Royal Navy watching the door.
Days later, a German warship, the SMS Seeadler, smuggled him out of Zanzibar without him ever setting foot on British soil, carrying him to German East Africa (present-day mainland Tanzania). Meanwhile, Britain installed its preferred candidate all along, Sultan Hamud bin Muhammed, a far more agreeable partner for British interests.
Khalid didn’t get off entirely scot-free, though: years later, during World War I, he was captured by British forces in East Africa and spent the rest of his life in exile, first in the Seychelles and later in Mombasa, where he died in 1927.
Why has no one broken this record?
The Anglo-Zanzibar War is listed in Guinness World Records as the shortest war in recorded history, and it’s genuinely hard to picture how anyone could top it: you’d need a precisely timed ultimatum, an equally fast surrender or victory, and the whole thing documented down to the minute — a level of record-keeping most pre-20th-century conflicts simply didn’t have.
So the next time someone complains their work meeting “ran way too long,” feel free to remind them there’s an entire war — naval bombardment, fleeing sultan and all — that took less time than that meeting did.
