Mother's Day was introduced to America in 1870 by Julia Ward Howe, who wanted to set aside a day of protest after the Civil War, in which mothers could come together and protest their sons killing other mothers' sons.
But the woman who really created Mother's Day as we know it was Anna Jarvis. Her mother had held Mother's Friendship Days to reunite families and neighbors separated during the war, and when she died, her daughter, Anna Jarvis, worked to proclaim an official Mother's Day to honor her mother and celebrate peace. And so on May 10, 1908, the first official Mother's Day celebrations took place in Grafton, West Virginia, and at a church in Philadelphia. In 1914, Woodrow Wilson designated the second Sunday of May as Mother's Day.
But Mother's Day became commercialized very quickly, especially in the floral industry, and Anna Jarvis was furious. She said, "What will you do to route charlatans, bandits, pirates, racketeers, kidnappers, and other termites that would undermine with their greed one of the finest, noblest, and truest movements and celebrations?" But flower sales and card sales continued to grow, and Anna Jarvis died in poverty and without any children of her own.
