The White Poppy is a peace sign that calls for the end of conflicts and is worn in honor of war’s military and civilian casualties. It symbolizes the idea that killing strangers is not the best method to resolve issues. On Remembrance Day, an artificial white poppy blossom is worn as an alternative to or in addition to the red poppy that is worn to commemorate the war dead. The Women’s Co-operative Guild of the United Kingdom first used the sign in 1933, and the newly founded Peace Pledge Union (PPU) joined the cause in 1934. Currently, the PPU is in charge of the White Poppy Appeal.
