The Full Story
On August 27, 1896, the British ultimatum expired at 9:00 AM. Within about 40 minutes, the war was over.
The Anglo-Zanzibar War lasted somewhere between 38 and 45 minutes, commonly called the shortest war in recorded history. Behind those minutes lay decades of British pressure to end the slave trade in East Africa.
Zanzibar had been the hub of the Indian Ocean slave trade. For years, Britain had pushed successive Sultans to restrict it: the export trade was banned and the slave market closed in 1873, though slavery itself remained legal. When Sultan Hamad died on 25 August 1896, Khalid bin Barghash seized the palace without British approval.
Britain would not allow it.
When Khalid refused to stand down, the Royal Navy opened fire. The Sultan's palace was destroyed. His one ship was sunk. There were approximately 500 Zanzibari casualties, killed and wounded. British casualties: 1 sailor injured.
Khalid fled to the German consulate. A new Sultan, Hamoud, was installed. On 6 April 1897 he decreed the abolition of slavery's legal status in Zanzibar, though concubines were excluded until 1909.
Roughly 40 minutes of war, and within a year Zanzibar's slaves were legally free. It is commonly called the shortest war ever fought.
Why This Matters
The war's immediate trigger was a succession dispute, but the settlement that followed ended slavery's legal status in Zanzibar within a year. British power in East Africa and the end of slavery there are part of the same story.
Key Facts
- ⚠Correction: the video says the war lasted exactly 38 minutes and was fought to end slavery; sources give 38 to 45 minutes, the documented trigger was the succession dispute after Sultan Hamad's death, the ~500 figure is Zanzibari casualties (killed and wounded), and the abolition decree followed on 6 April 1897 (Britannica, Cambridge Law and History Review).
