World's Shortest War Lasted 38 Minutes

The catalyst for history's briefest military conflict was a classic power struggle. Upon the death of the pro-British Sultan of Zanzibar in August 1896, his cousin Khalid bin Barghash seized the throne without British approval. This move directly defied a treaty that essentially made Zanzibar a British protectorate, giving the empire the right to approve any new successor. Barricading himself inside the royal palace with roughly 2,800 loyalists and several pieces of artillery, Khalid ignored British demands to stand down in favor of their preferred candidate.

The British Empire responded with a swift and decisive ultimatum: surrender and leave the palace by 9:00 AM on August 27, or face the consequences. When the deadline passed without compliance, five Royal Navy warships anchored in the harbor opened fire. The ensuing bombardment was overwhelming. In less than an hour, the palace was a smoldering ruin, the Sultan's artillery was silenced, and his flag was felled, signaling his surrender. The conflict officially ended after just 38 minutes.

Sultan Khalid fled to the German consulate for asylum, and the British quickly installed their own choice on the throne, securing their influence for decades. The lopsided conflict resulted in an estimated 500 casualties among the Zanzibari palace defenders, while the British suffered only a single non-fatal injury. The lightning-fast war served as a brutal demonstration of the British Empire's military superiority and its intolerance for challenges to its colonial authority.
