The Ulster Volunteer Force (UVF) is an Ulster loyalist paramilitary group in Northern Ireland. It emerged in 1966 and is named after the original UVF of the early 20th century. Its first leader was Gusty Spence, a former British soldier. The group undertook an armed campaign of almost thirty years during the Troubles. It declared a ceasefire in 1994 and officially ended its campaign in 2007, although some of its members have continued to engage in violence. The group is classified as a terrorist organization by the United Kingdom, Republic of Ireland and United States.
