The modern Mother's Day began in the United States, at the initiative of Anna Jarvis in the early 20th century. It is not directly related to the many traditional celebrations of mothers and motherhood that have existed throughout the world over thousands of years, such as the Greek cult to Cybele, the mother god Rhea, the Roman festival of Hilaria, or the Christian Laetare Sunday celebration. However, in some countries, Mother's Day is still synonymous with these older traditions.
The American version of Mother's Day has been criticized for having become too commercialized. Founder Jarvis herself regretted this commercialism and expressed that this was never her intention. In response, Constance Adelaide Smith successfully advocated for Mothering Sunday as a commemoration of a broader definition of motherhood in many other parts of the English-speaking world.
