# The Anglo-Zanzibar War: History's 38-Minute War

*History & War · Eleanor Hartwell · 2026-10-13*

## TL;DR

On 27 August 1896, Britain and the Sultanate of Zanzibar fought a war that lasted about 38 minutes. Sultan Khalid bin Barghash refused a British ultimatum to step down, so Royal Navy ships bombarded his palace. He fled, and Britain installed its preferred sultan.

## Key facts

- Sultan Hamad bin Thuwaini of Zanzibar died on 25 August 1896, and his cousin Khalid bin Barghash seized the throne without British approval.
- Britain demanded Khalid leave the palace by 9:00 a.m. on 27 August 1896, and he refused, so Royal Navy ships opened fire.
- The bombardment lasted roughly 38 minutes, destroying much of the palace and killing an estimated 500 people among Khalid's defenders.
- Khalid fled to the German consulate and escaped to German East Africa, while Britain installed Hamoud bin Mohammed as sultan.
- Zanzibar remained a British protectorate until 1963, and the 1896 conflict is widely cited as the shortest war ever fought.

## The Morning a War Lasted Less Than a Lunch Break

On the morning of 27 August 1896, the Royal Navy and the Sultanate of Zanzibar fought a war that began and ended before most people had finished their breakfast. The Anglo-Zanzibar War lasted roughly 38 minutes, which is why it is remembered as the shortest war in history. The shooting is generally timed from about 09:02 to about 09:40. Think about that gap: a bombardment, a surrender, and the collapse of a government, all squeezed into the space between two cups of tea.

To understand why such a lopsided, clock-stopping event could happen at all, you have to picture Zanzibar in the late 19th century. This small island off East Africa was the commercial heart of the region, and it carried a nickname that sounded almost romantic: the Spice Island. Cloves, ivory, and human beings moved through its ports. For Britain, the island mattered for a colder reason. Whoever controlled Zanzibar sat astride the Indian Ocean trade routes, and in an age of empires, that was not a detail. It was the whole point.

So the stage was set long before the guns opened fire. What turned a tense harbor into a shooting gallery was a death and a succession, and once the ultimatum clock started running, there was almost no time left for anyone to step back.

## A Sudden Death, a Defiant Cousin, and a British Ultimatum

Sultan Hamad bin Thuwaini of Zanzibar died suddenly on 25 August 1896. He had been Britain's man on the throne, friendly to London, reliable, and then he was simply gone. Whether poison was involved has never been settled; the death was sudden, the suspicion lingered, and no proof ever followed.

Into that vacuum stepped his cousin, Khalid bin Barghash. He took the throne before anyone in London could object, and the objection came fast. Britain refused to recognize him. Under the treaty terms Zanzibar had signed, a new sultan needed British consent, and Khalid had not asked. Britain viewed his accession as illegitimate, treating it as an unlawful transfer of power, though that exact phrasing cannot be confirmed as a direct quote.

What followed was a two-day standoff with a clock attached. The British demanded that Khalid leave the palace and surrender by 09:00 on 27 August 1896. He refused. Instead of packing, he prepared the palace for a fight, gathering roughly 2,800 soldiers along with several cannons and machine guns. Exact figures vary by source, but the shape of the thing is clear: a young sultan betting that defiance would buy him time, or respect, or something.

He had until nine in the morning. The ultimatum did not move.

## 09:02 to 09:40: The Palace Burns

At 09:02 on the morning of 27 August 1896, the guns of the Royal Navy opened fire on the Sultan's palace in Zanzibar, and the Anglo-Zanzibar War had begun in earnest. Anchored in the harbor that morning were HMS St. George, HMS Philomel and HMS Sparrow, with other vessels such as HMS Racoon and HMS Thrush also present in the roads. The ultimatum had run out. The ships did not wait.

What followed was less a battle than a demonstration. Shells walked across the palace compound and the surrounding structures, and fires broke out almost at once. One detail has hardened into legend over the years: that the very first shots struck the arsenal and touched off the explosion that left the whole palace in flames. That is how the morning is often described, but it cannot be reliably confirmed that those opening rounds hit the arsenal specifically and started the blaze. What is certain is that the palace burned.

Zanzibari gunners tried to answer. The palace artillery fired back, but the return fire was thin and short-lived, and the guns fell silent quickly against the weight of the bombardment. For roughly thirty-eight minutes the shelling continued. Then, at about 09:40, the flag came down and the firing stopped. The shortest war in history was over before most of the world had finished breakfast.

From the first shell at 09:02 to the struck flag at 09:40, the entire engagement fit inside a single morning errand. The arithmetic is the point: a sovereign palace, thousands of defenders, and one Royal Navy squadron, resolved in thirty-eight minutes.

## 500 Dead, One Wounded Sailor, and a Sultan in Hiding

When the guns finally went quiet at 09:40 on 27 August 1896, the arithmetic of the Anglo-Zanzibar War was already written in stone. Roughly 500 Zanzibaris lay dead. On the British side, exactly one sailor had been wounded. Five hundred to one, and the whole exchange had lasted about 38 minutes.

Those numbers are not a rounding error or a bit of Victorian boasting. They are the clearest picture we have of what a modern naval bombardment does to a wooden palace defended by obsolete artillery. The defenders of Sultan Khalid bin Barghash had roughly 2,800 men, several cannons, and machine guns. It did not matter. The guns fell silent within minutes, and the flag came down.

### Where the Sultan Went

Khalid did not stay to be captured. He fled the burning palace and took refuge in the German consulate, where he reportedly hoped the German flag would shield him from British demands. It bought him time, not a throne. Britain moved fast: Hamoud bin Mohammed, the man London had wanted all along, was installed as sultan almost immediately afterward. Khalid's reign had lasted barely two days.

### The Long Shadow

With a compliant sultan on the seat, Zanzibar effectively became a British protectorate. The island's foreign policy, its trade, and its future now ran through London. That arrangement held for generations. Zanzibar stayed under British rule until 1963. Independence arrived in December 1963, and within weeks the Zanzibar Revolution of January 1964 swept the old order away and established a republic.

So the 38 minutes did not just end a war. They locked in six decades of colonial control, and the reckoning that followed in 1964 was every bit as sudden as the bombardment itself.

### The Cannons in Greenwich: A Spoils Story That Doesn't Quite Hold

Here is the detail that gets repeated most often about the Anglo-Zanzibar War, and it is also the one that deserves the most caution. The popular version says the palace's defensive cannons were Ottoman-made bronze barrels, and that after the fighting British soldiers carried them off to London as spoils, where they sit today in the National Maritime Museum in Greenwich. Neither half of that story can be reliably confirmed.

What we can say is narrower. Some of the artillery defending the palace is described as old or obsolete, which fits the broader picture of a garrison outmatched before the first shell flew. As for the Ottoman origin of those bronze barrels, that specific claim cannot be reliably confirmed either.

The same goes for the journey to Greenwich. It is a tidy ending, a physical relic of a 38-minute war sitting quietly in a London museum, and tidiness is exactly why it travels so well. But it cannot be reliably confirmed that specific palace cannons were taken to London as spoils, let alone that they are the ones on display at the National Maritime Museum.

So treat it as a story, not a fact. The verified record of the Anglo-Zanzibar War is dramatic enough without it: the bombardment, the fire, the flag coming down at 09:40, and roughly 500 dead on one side against a single wounded sailor on the other. The cannons in Greenwich make a better ending. They just may not be the true one.


## Frequently asked questions

**What was the Anglo-Zanzibar War and why is it called the shortest war in history?**

The Anglo-Zanzibar War was a bombardment of the Sultan's palace in Zanzibar on the morning of 27 August 1896, fought between British warships and the forces of Sultan Khalid bin Barghash. It lasted roughly 38 minutes, which is why it is widely called the shortest war in recorded history.

**How long did the Anglo-Zanzibar War last and when did it take place?**

It began at about 09:02 on 27 August 1896 and ended around 09:40 the same morning, a span of some 38 minutes. The British ultimatum had expired at 09:00, and the naval bombardment of the palace complex followed almost immediately.

**Who was Sultan Khalid bin Barghash and why did he refuse the British ultimatum?**

Khalid bin Barghash was the cousin of Sultan Hamad bin Thuwaini, who died suddenly on 25 August 1896. Khalid seized the throne, and when the British demanded he leave the palace by 09:00 on 27 August, he refused, instead preparing its defense with about 2,800 soldiers, several cannons and machine guns.

**How many people died in the Anglo-Zanzibar War?**

Around 500 Zanzibaris were killed, most of them defenders caught in the shelling of the palace and its surroundings. On the British side, the toll was a single wounded sailor. That imbalance is the number most histories of the conflict return to.

**Why did the British bombard the palace?**

Britain wanted Khalid removed and a sultan friendly to its interests installed in his place. When he refused to stand down, the warships opened fire to force him out, clearing the way for a ruler who would accept British terms.

**What happened to Khalid after the war?**

Khalid fled the palace as it burned and took refuge in the German consulate. He escaped British custody by sheltering there, and the British never captured him in the immediate aftermath of the bombardment.

**How did the Anglo-Zanzibar War lead to Zanzibar becoming a British protectorate?**

Britain installed Hamoud bin Mohammed as sultan right after Khalid's departure, and Zanzibar effectively became a British protectorate. That arrangement held until 1963, when the country gained independence, followed by a revolution in 1964 that turned it into a republic.

**Where are the palace cannons today?**

This one is hard to pin down. The claim that some of the palace's defensive cannons were taken to London as spoils and are now displayed at the National Maritime Museum in Greenwich is repeated in some accounts, but it cannot be reliably confirmed, so treat it as unverified rather than settled fact. Editorial note: Details that remain unconfirmed, including exact casualty figures and the precise duration of the fighting, are presented here as estimates rather than settled facts.
