The spread of the poppy as a symbol

The poem then inspired an American academic named Moina Michael to adopt the poppy in memory of those who had fallen in the war. She campaigned to get it adopted as an official symbol of Remembrance across the United States and worked with others who were trying to do the same in Canada, Australia, and the UK.

Also involved with those efforts was a French woman, Anna Guérin who was in the UK in 1921 where she planned to sell the poppies in London.

There she met Earl Haig, founder of the Royal British Legion, who was persuaded to adopt the poppy as an emblem for the Legion in the UK. The Legion, which had been formed in 1921, ordered nine million poppies and sold them on 11 November that year.
