Some wars can last for years and years, while others are relatively short lived, but no war, at least to date, has been as short as the Anglo-Zanzibar War that was fought on August 27, 1896. The war was so short, that it is estimated to have lasted between 38 and 40 minutes…yes, I said minutes. The cause of the war was the sudden and unexplained death of pro-British Sultan Hamad bin Thuwaini, followed by the subsequent succession of Sultan Khalid bin Barghash, who was suspected of killing his uncle in order to take over. The British authorities preferred Hamud bin Muhammed, who was well known for his favorable stance toward British interests. A treaty signed in 1886, called for any candidate for accession to the sultanate, to be approved by the British consul, and Khalid had not fulfilled this requirement. The British considered this an act of war and sent an ultimatum to Khalid demanding that he order his forces to stand down and leave the palace. In response, Khalid called up his palace guard and barricaded himself inside the palace.
At 9:00am East Africa Time on 27 August, the ultimatum expired. The British had gathered three cruisers, two gunboats, 150 marines and sailors, and 900 Zanzibaris in the harbor area. The Royal Navy contingent were under the command of Rear-Admiral Harry Rawson while their Zanzibaris were commanded by Brigadier-General Lloyd Mathews of the Zanzibar army, who was also the First Minister of Zanzibar. Around 2,800 Zanzibaris defended the palace, most of whom were recruited from the civilian population, but they also included the sultan’s palace guard and several hundred of his servants and slaves. The defenders had several artillery pieces and machine guns, which were set in front of the palace sighted at the British ships. The first bombardment, launched at 9:02am quickly set the palace on fire, disabling the defending artillery. A small naval action took place in the harbor, with the British sinking the Zanzibari royal yacht HHS Glasgow and two smaller vessels. The palace fired some shots ineffectually at the pro-British Zanzibari troops as they approached the palace. The flag at the palace was shot down and fire ceased at 9:40am. It was almost a matter of ready…aim…oh, never mind.
Sultan Khalid bin Barghash’s forces sustained roughly 500 casualties, while the British only had one sailor injured. Sultan Khalid immediately ran to the German consulate, where he was given asylum and then he escaped to German East Africa, located in the mainland part of present day Tanzania. The British quickly placed Sultan Hamud bin Muhammed in power at the head of a puppet government. The war marked the end of the Zanzibar Sultanate as a sovereign state and the start of a period of heavy British influence. The badly damaged palace complex was completely changed by the war. The harem, lighthouse and palace were demolished as the bombardment had left them unsafe. The palace site was turned into an area of gardens, and a new palace was erected on the site of the harem. The House of Wonders was almost undamaged and would later become the main secretariat for the British governing authorities. During renovation work on the House of Wonders in 1897, a clock tower was added to its frontage to replace the lighthouse lost to the shelling. The wreck of the Glasgow remained in the harbor in front of the palace, where the shallow waters ensured that her masts would remain visible for several years to come, as a reminder of what would happen if the treaty was not followed. In 1912, it was finally broken up for scrap.
