Over the course of the Somali Civil War, there have been many revolutionary movements and militia groups run by competing rebel leaders which have held de facto control over vast areas of the country.
First Somali resistance group.
Took part in a 1982 Ethiopian border offensive against Somalia.
The SSDF tried to ally with the SNM in 1983, but they failed to agree to a common strategy.
The SNF was a political revolutionary movement and armed militia in Somalia. Initially made up of loyalists to former President of Somalia Siad Barre and the remnants of the Somali National Army forces after his ouster from office, the SNF's intent and goal was to recapture Mogadishu and reinstate Barre's regime. Later, under General Omar Hagi Masallah and General Ahmed Ali, the SNF united the Marehan with the other Darod clans led by General Mohammed Said Hersi "Morgan", and then attempted to conquer the region around Kismayo to form the autonomous district of Jubaland.
Isaaq tribe members had founded the movement in 1981 as emigres to London with the express purpose of overthrowing the Barre regime. They eventually moved to Addis Ababa, Ethiopia, and gained the support of the Ethiopian government.
On January 2, 1982 operating near Berbera, the group attacked Mandera Prison to free political prisoners while simultaneously raiding Cadaadle armory.
Between 1985 and 1987, the SNM conducted many attacks on government facilities and troops based out of camps in Ethiopia.
By 1988, the SNM moved out of their camps in Ethiopia and began operating in northern Somali republic , the area now known as Somaliland. They even temporarily occupied the provincial capitals of Burao and Hargeysa.
