The red poppy is the United Kingdom's symbol of remembrance for military personnel who died in war—worn from late October through Remembrance Day (November 11) and Remembrance Sunday (second Sunday in November).
1915: Lt. Col. John McCrae's poem "In Flanders Fields"—poppies blooming on Western Front graves.
1918: Moina Michael (US) pledges to wear poppy; Anna Guérin (France) organizes artificial poppy sales for veterans.
1921: British Legion adopts poppy; first UK Poppy Appeal raises £106K (equivalent ~£5M today).
Royal British Legion produces ~40M poppies/year (factory in Aylesbury employs disabled veterans). Donation-based—no fixed price. Funds → veterans' welfare, housing, employment, mental health, families.
Wearing etiquette: Left lapel (near heart). No official rule on when to start/stop—traditionally after Oct 31 until Nov 11 or Remembrance Sunday.
Near-universal participation across class, region, politics. Public figures expected to wear; omission noted. Two-minute silence at 11:00 Nov 11—transport, workplaces, schools stop. The poppy is Britain's secular sacrament: a nation pausing to honor its war dead.
