Stop the War Coalition
UK peace advocacy group (2001-)

The Stop the War Coalition (StWC), informally known simply as Stop the War, is a British group that campaigns against the United Kingdom's involvement in military conflicts.
It was established on 21 September 2001 to campaign against the impending war in Afghanistan. It then campaigned against the impending invasion of Iraq; the 15 February 2003 protest organised by the Coalition along with the Campaign for Nuclear Disarmament (CND) and the Muslim Association of Britain (MAB), was the largest public demonstration in British history.
Since then, the Coalition has campaigned against the 2011 military intervention in Libya and opposed UK involvement in the War against the Islamic State, stating that airstrikes would only fuel extremism. It opposed sending military aid to Ukraine during the Russian invasion, stating that it risks starting a war between NATO and Russia, a position which drew criticism from Andrew Fisher. It has called for ceasefires in the Russo-Ukrainian War and in the Gaza war.
The group has been criticised for allegedly excusing military aggression by enemies of the US and UK, and critics accuse it of being "more anti-West than anti-war".
Formation and leading members
The impetus to form the Stop the War Coalition came following the September 11 attacks in the United States. The Coalition was launched at a public meeting of 2,000 people at Friends House on Euston Road in London, on 21 September which was chaired by Lindsey German, then active in the Socialist Workers Party (SWP). "The Stop the War Coalition has been formed to encourage and mobilise the largest possible movement against the war", said the founding statement.

Why this record matters
The phrase “uK peace advocacy group (2001-)” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Aug 7, 2026. The linked authority identifier is Q1571260. VIAF identifies the subject as 152827306. The Library of Congress control number is no2008013640. 3 of 4 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 2001, 2003 and 2011.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
