 As a result of its immediate popularity, parts of the poem were used in efforts and appeals to recruit soldiers and raise money selling war bonds.Its references to the red poppies that grew over the graves of fallen soldiers resulted in the remembrance poppy becoming one of the world's most recognized memorial symbols for soldiers who have died in conflict.The poem and poppy are prominent Remembrance Day symbols throughout the Commonwealth of Nations, particularly in Canada, where "In Flanders Fields" is one of the nation's best-known literary works.
