Dervish resistance

Following the Berlin Conference, the British, Italians, and Ethiopians sought to claim lands inhabited by the Somalis. The Dervish movement, led by Sayid Muhammed Abdullah Hassan, existed for 21 years, from 1899 until 1920. The Dervish movement successfully repulsed the British Empire four times and forced it to retreat to the coastal region. Because of these successful expeditions, the Dervish movement was recognized as an ally by the Ottoman and German empires. The Turks named Hassan Emir of the Somali nation, and the Germans promised to officially recognise any territories the Dervishes were to acquire. After a quarter of a century of holding the British at bay, the Dervishes were finally defeated in 1920 as a direct consequence of Britain's use of aircraft.
