So far as is known, white poppies were first produced by the Co-operative Women's Guild in Britain in 1933, and later the Peace Pledge Union undertook their annual distribution. In subsequent years, white poppies spread to other countries around the globe, and the white poppy became an international symbol of remembrance and peace. The white poppy is an international symbol of remembrance for all the casualties of war - civilians and armed forces personnel - and of peace. Some people see it as an alternative to the red poppy, others see it as complementary; some choose to wear both poppies, some one or the other, and some no poppy at all.
