The shortest war in history lasted less than an hour and ended a sultanate.
On August 27, 1896, the United Kingdom and the Sultanate of Zanzibar engaged in a conflict that concluded in under 45 minutes. Triggered by a disputed succession, the brief bombardment of the palace effectively dismantled Zanzibar's sovereignty and solidified British colonial control over the island for decades to come.
The conflict began following the sudden death of Sultan Hamad bin Thuwaini on August 25, 1896. His nephew, Khalid bin Barghash, seized the palace in Zanzibar Town without the British approval required by an 1890 protectorate agreement. British authorities, who favored the more compliant Hamoud bin Mohammed, issued an ultimatum demanding that Khalid vacate the palace by 09:00 on August 27. When Khalid refused, British naval forces under Rear-Admiral Harry Rawson initiated a bombardment of the wooden palace complex.
The engagement was remarkably lopsided. While Khalid had mustered roughly 2,800 defenders, including palace guards and civilians, they were no match for the Royal Navy’s cruisers and gunboats. The palace was quickly set ablaze, and the sultan's small naval vessel, the HHS Glasgow, was sunk after attempting to return fire. By 09:46, the palace flag had been struck and the fighting ceased. Approximately 500 of the sultan's forces were killed or wounded, largely due to the fire, while only one British sailor sustained injuries.
Khalid fled to the German consulate, eventually securing passage to German East Africa. The British promptly installed Hamoud bin Mohammed as a puppet ruler, who subsequently abolished slavery as demanded by his benefactors. The war marked the definitive end of Zanzibar as a sovereign state, transitioning it into a period of total British influence. This lopsided victory ensured that no further rebellions against British authority occurred on the island for the next 67 years, until the protectorate ended in 1963.
The exact duration of the war remains a subject of minor historical debate, with estimates ranging from 38 to 45 minutes depending on whether the start is marked by the order to fire or the first impact. Regardless of the precise timing, the event stands as a stark demonstration of imperial power, where a single morning of naval artillery fire permanently altered the political trajectory of an entire nation.
