The Royal British Legion, sometimes referred to as simply The Legion, is the United Kingdom's leading charity providing financial, social and emotional support to millions who have served or who are currently serving in the British Armed Forces, and their dependants. The British Legion was founded in 1921 as a voice for the ex-Service community as a merger of four organisations: the Comrades of the Great War, the National Association of Discharged Sailors and Soldiers, the National Federation of Discharged and Demobilized Sailors and Soldiers and the Officers' Association. It was granted a Royal Charter on 29 May 1971 to mark its fiftieth anniversary which gives the Legion the privilege of the prefix 'Royal'.
Earl Douglas Haig, commander of the Battle of the Somme and Passchendaele was one of the founders of the Legion, and was President until his death. Perhaps known best for the annual Poppy Appeal and Remembrance services, including the Festival of Remembrance, the Legion was born as a campaigning organisation and has been active behind the scenes in promoting the welfare and interests of the Services and ex-Service community for 86 years.
