The Dervish Movement (Somali: Dhaqdhaqaaqa Daraawiish) also known as the Dervish State was an armed resistance movement and polity in the Horn of Africa between 1899 and 1920, which was led by the Salihiyya Sufi Muslim poet and militant leader Mohammed Abdullah Hassan, also known as Sayyid Mohamed, who called for independence from the British and Italian colonisers and for the defeat of Ethiopian forces. The Dervish movement aimed to remove the British and Italian influence from the region and restore an "Islamic system of governance with a Sufi doctrine as its foundation", according to Mohamed-Rahis Hasan and Salada Robleh.
Hassan established a ruling council called the Khususi consisting of Sufi tribal elders and spokesmen, added an adviser from the Ottoman Empire named Muhammad Ali, and thus created a multi-clan Islamic movement in what led to the eventual creation of the state of Somalia.
