This war lasted over two decades until the British Royal Air Force, having honed their skills in WWI, led a devastating bombing campaign against dervish strongholds in 1920, under which Hasan was forced to flee, dying of pneumonia soon after.
The dervish struggle was the one of the longest and bloodiest anti-Imperial resistance wars in sub-Saharan Africa, and cost the lives of nearly a third of northern Somalia's population, as well as egregious casualties on the Ethiopian and British sides.
The Ogaden War of 1977-78 between Somalia and Ethiopia and the consequent refugee influx forced Somalia to depend for its economic survival on humanitarian handouts.
By the end of the war, most of the country's physical infrastructure was destroyed, and what was not destroyed during the war is rapidly deteriorating.
One major consequence of the split-up was a civilwar between the two organizations during 1972-74.
Ethiopian defeats gave the EPLF control of the north, west and, finally the east (with the capture of the port city of Massawa in 1990).
