World's Shortest War Lasted 38 Minutes

The Anglo-Zanzibar War, a blink-and-you-miss-it conflict on August 27, 1896, was a dramatic display of late 19th-century imperial power. The immediate catalyst was the sudden death of Sultan Hamad bin Thuwaini, a pro-British ruler, on August 25, 1896. His cousin, Khalid bin Barghash, promptly seized the throne without British approval, a clear violation of a 1890 treaty that effectively made Zanzibar a British protectorate and required British consent for succession. The British, who preferred another candidate more amenable to their interests, issued an ultimatum demanding Khalid step down by 9:00 AM on August 27.

Khalid, however, refused to comply, barricading himself in the palace with approximately 2,800 loyal men, including his palace guard and hastily recruited civilians, along with some artillery pieces. Despite his preparations, his forces were no match for the overwhelming naval superiority of the British Royal Navy, which had amassed two cruisers and three gunboats in the harbor.

At precisely 9:02 AM, when the ultimatum expired, the British warships opened fire on the palace. The bombardment was devastatingly swift, destroying Khalid's artillery and setting the palace ablaze within minutes. The Zanzibari royal yacht, the HHS Glasgow, was also quickly sunk. By 9:40 AM, the Sultan's flag had been shot down, and the shelling ceased. The entire engagement lasted a mere 38 to 45 minutes, solidifying its place in history as the shortest recorded war.

In the aftermath, Khalid fled to the German consulate, eventually finding asylum in German East Africa. The British swiftly installed their preferred candidate, Hamoud bin Mohammed, as the new Sultan, who promptly agreed to all British terms, including the abolition of slavery. While the British suffered only one injured sailor, approximately 500 Zanzibaris were killed or wounded, largely due to the intense bombardment and subsequent fires. This brief but brutal conflict underscored the immense technological and military disparity between European colonial powers and local states during the "Scramble for Africa."
