Step 1 : Introduction to the question "How long was the shortest war in history?"
The Anglo-Zanzibar War only lasted a whopping 38 minutes, and holds the record of being the shortest war in recorded history. The war began in 1896 when Sultan Khalid bin Bargash of Zanzibar seized power following the suspicious death of his uncle. The British, deeming Khalid too independent, issued an ultimatum to Khalid demanding that he order his forces to stand down and leave the palace. When Khalid refused, British warships opened fire on the Sultan's palace, quickly overwhelming his defenses. Khalid fled, resulting in a swift British victory.
