The Somaliland War of Independence (Somali: Dagaalkii Xoraynta Soomaaliland, lit. 'Somaliland Liberation War') was a rebellion waged by the Somali National Movement (SNM) against the ruling military junta in Somalia led by General Siad Barre lasting from its founding on 6 April 1981 and ended on 18 May 1991 when the SNM declared what was then northern Somalia independent as the Republic of Somaliland. The conflict served as the main theater of the larger Somali Rebellion that started in 1978. The conflict was in response to the harsh policies enacted by the Barre regime against the main clan family in Somaliland, the Isaaq, including a declaration of economic warfare on the clan-family. These harsh policies were put into effect shortly after the conclusion of the disastrous Ogaden War in 1978.
As a direct response to the harsh policies enacted by the Barre regime against the Isaaq people, in April 1981 a group of Isaaq businesspeople, students, former civil servants and former politicians founded the Somali National Movement in London. From February 1982, Isaaq army officers and fighters started moving into Ethiopia where they formed the nucleus of what would later become the armed wing of the SNM. Throughout the early to mid 1980s SNM launched a guerrilla war against the Barre regime through incursions and hit and run operations on army positions within Isaaq territories, especially into the Waqooyi Galbeed and Togdheer regions.
