The Somaliland campaign, also called the Anglo-Somali War or the Dervish rebellion, was a series of military expeditions that took place between 1900 and 1920 in modern-day Somaliland. The British were assisted in their offensives by the Ethiopian Empire and the Kingdom of Italy.
The Dervish led by Sayid Muhammed Abdullah Hassan, continued independently from about (24–26) years between 1896/1900–1921. The Dervish movement had successfully repulsed the British Empire four times and forced it to retreat to the coastal region.,
With the defeat of the Ottoman and German empires in World War I, the Dervish movement lacked any allies. The British thus turned their attention to the Dervishes, who launched a massive combined arms offensive on their strongholds of the Taleh forts. The British also aerially bombed the Dervish capital of Taleh, bringing the conflict to an end.
