Remembrance Day is commemorated every year on 11 November to mark the armistice signed between the Allies of World War I and Germany at Compiègne, France, for the cessation of hostilities on the Western Front of World War I, which took effect at eleven o’clock in the morning—the “eleventh hour of the eleventh day of the eleventh month” of 1918. The use of the 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 Europe that overlies a part of Belgium.
