Anglo-Zanzibar War

Date: August 27, 1896 • Location: London, United Kingdom

This milestone marked the outbreak and beginning of this historic period, which spanned 1896.

In the shortest recorded war in history, the Sultanate of Zanzibar surrendered to the United Kingdom after less than an hour of conflict.

The Anglo-Zanzibar War was a military conflict fought between the United Kingdom and the Sultanate of Zanzibar on 27 August 1896. The conflict lasted between 38 and 45 minutes, marking it as the shortest recorded war in history. The immediate cause of the war was the suspicious death of the pro-British Sultan Hamad bin Thuwaini on 25 August 1896 and the subsequent succession of Sultan Khalid bin Barghash. The British authorities preferred Hamoud bin Mohammed, who was more favourable to British interests, as sultan. The agreement of 14 June 1890, instituting a British protectorate over Zanzibar, specified that a candidate for accession to the sultanate should obtain the permission of the British consul; Khalid had not fulfilled this requirement. The British considered this a casus belli 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.
