The remembrance poppy is an artificial flower that has been used since 1921 to commemorate military personnel who have died in war, and represents a common or field poppy, Papaver rhoeas. Inspired by the World War I poem "In Flanders Fields", and promoted by Moina Michael, they were first adopted by the American Legion to commemorate American soldiers killed in that war (1914–1918). They were then adopted by military veterans' groups in parts of the British Empire.
Today, they are mostly used in the United Kingdom, Canada, Australia and New Zealand, to commemorate their servicemen and women killed in all conflicts. There, small artificial poppies are often worn on clothing leading up to Remembrance Day/Armistice Day, and poppy wreaths are often laid at war memorials. In Australia and New Zealand, they are also worn on Anzac Day.
The Royal British Legion's Poppy Appeal has caused some controversy, with some—including British Army veterans—arguing that it has become excessive, is being used to marshal support behind British military campaigns, and that public figures are pressured to wear poppies.
The remembrance poppy was inspired by the World War I poem "In Flanders Fields". Its opening lines refer to the many poppies that were the first flowers to grow in the churned-up earth of soldiers' graves in Flanders, a region of Belgium. It is written from the point of view of the dead soldiers and, in the last verse, they call on the living to continue the conflict. The poem was written by Canadian physician, Lieutenant Colonel John McCrae, on 3 May 1915 after witnessing the death of his friend, a fellow soldier, the day before. The poem was first published on 8 December 1915 in the London-based magazine Punch.
