The official Mother’s Day holiday arose in the early 1900s as a result of the efforts of Anna Jarvis, daughter of Ann Reeves Jarvis. Following her mother’s death in 1905, Anna Jarvis conceived of Mother’s Day as a way of honoring the sacrifices mothers made for their children. After gaining financial backing from a Philadelphia department store owner named John Wanamaker, in May 1908 she organized the first official Mother’s Day celebration at a Methodist church in Grafton, West Virginia. That same day also saw thousands of people attend a Mother’s Day event at one of Wanamaker’s stores in Philadelphia.
Arguing that American holidays were biased toward male achievements, Jarvis started a massive letter writing campaign to newspapers and prominent politicians urging the adoption of a special day honoring motherhood. By 1912 many states, towns, and churches had adopted Mother’s Day as an annual holiday, and Jarvis had established the Mother’s Day International Association to help promote her cause. Her persistence paid off in 1914 when President Woodrow Wilson signed a measure officially establishing the second Sunday in May as Mother’s Day.
