Moina Michael conceived of an idea in 1918 after reading a poem, to wear red poppies on Memorial day in honor of those who died serving the nation during war and sold poppies to her friends and co-workers with the money going to benefit servicemen in need. Later, Madam Guerin from France was visiting the United States and learned of this new custom. When she returned to France, she made artificial red poppies to raise money for war orphaned children and widowed women. This tradition spread to other countries.
In 1921, the practice of selling poppies was taken up by the American Legion Auxiliary and in1922 by the VFW. Two years later their "Buddy" Poppy program was selling artificial poppies made by disabled veterans. The practice continues today.
Several southern states have an additional separate day for honoring the Confederate war dead: January 19 in Texas, April 26 in Alabama, Florida, Georgia, and Mississippi; May 10 in South Carolina; and June 3, Jefferson Davis' birthday, in Louisiana and Tennessee.
