Sayid Mohamed Abdullah Hassan (Somali: Sayid Maxamed Cabdulle Xasan; (1856 – 1920) was a Somali religious and military leader in the Dervish territories encompassed by fortifications which Dervishes called Dhulbahante garesas, amidst which they intended a Darawiish (Dervish) polity in Ciid-Nugaal wherein Diiriye Guure was monarch and whereby Sayid Mohamed was the emir of king Diiriye Guure. It was subdivided into 13 administrative divisions of which the four largest were Shiikhyaale, Dooxato, Golaweyne and Miinanle, a setting which in the midst of colonial expansionism eventually set the stage for a two-decade long confrontation with various colonial empires including the British, Italians, and Abyssinians.
