The Origins of Mother's Day

According to the Library of Congress and other sources, Anna Jarvis is credited with the campaign that led to a nationally-celebrated Mother's Day. Jarvis's mother was known for organizing women's groups to promote health and friendship. 
In the wake of her mother's death in 1905, Jarvis wanted to set aside a day to honor the sacrifices of mothers for their children. In May 1908, she organized the first official Mother's Day celebration.
