The World's Shortest War Lasted Minutes

The swift military engagement that unfolded on August 27, 1896, between the British Empire and the Sultanate of Zanzibar stands as a unique event in history, remarkable for its extreme brevity. This conflict, often cited as the shortest ever recorded, was the culmination of escalating tensions following the sudden death of Sultan Hamad bin Thuwaini, who was seen as pro-British. His cousin, Khalid bin Barghash, seized the throne without British approval, directly violating an 1890 treaty that stipulated British consent for any new sultan. The British, keen to maintain their influence in the strategically important island nation, issued an ultimatum demanding Khalid step down.

Khalid bin Barghash refused to comply, instead barricading himself in the palace with an estimated 2,800 defenders and an assortment of artillery pieces, some of which were diplomatic gifts. In response, the Royal Navy, under Rear-Admiral Harry Rawson, positioned a formidable force of warships, including cruisers and gunboats, in Zanzibar's harbor, along with British marines and pro-British Zanzibari troops. At precisely 9:00 AM, after the ultimatum expired, the British ships opened fire on the palace.

The bombardment was devastatingly effective, quickly silencing Khalid's defenses and setting the palace ablaze. The Sultan's royal yacht, the HHS Glasgow, was also swiftly sunk. Within minutes, the resistance crumbled. By 9:38 AM, the Sultan's flag was lowered, signaling surrender. The entire conflict lasted between 38 and 45 minutes, resulting in approximately 500 casualties for Zanzibar's forces, while only one British sailor was reported injured. Khalid bin Barghash fled to the German consulate and later to German East Africa, and a British-favored sultan was quickly installed, solidifying British control over Zanzibar.
