Hassan Adan Wadadid in the context of "Somali National Movement"

The Somali National Movement (Somali: Dhaqdhaqaaqa Wadaniga Soomaaliyeed, Arabic: الحركة الوطنية الصومالية) was one of the first and most important organized guerilla groups and Mujahideen groups that opposed the Siad Barre regime in the 1980s to the 1990s, as well as being the main anti-government faction during the Somaliland War of Independence. The organisation was founded in London, England, on April 6, 1981 by Hassan Isse Jama, Hassan Adan Wadadid, and Ahmed Mohamed Gulaid and other former Somali diplomats, who stated that initially the group's purpose was to overthrow the Siad Barre regime.

In May 1991, the organisation declared an independent Republic of Somaliland in the region that had constituted British Somaliland before independence and unification with the former colony of Italian Somaliland in 1960 after the Somaliland War of Independence.
