The Haig Fund (more properly the Earl Haig Fund) is a charity set up in 1921 by Field Marshal Douglas Haig, 1st Earl Haig to assist ex-servicemen. Today, the Haig Fund continues to support veterans from all conflicts and other military actions involving British Armed Forces up to today. Its members sell remembrance poppies in the weeks before Remembrance Day/Armistice Day. The words "Haig Fund" are no longer inscribed on the black button in the centre of each poppy; instead it reads "Poppy Appeal".
