Mothers Day started as a spring celebration in ancient Greece to honor Rhea, the Mother of the Deities.
In the 1600s Christians in England celebrated Mothering Sunday on the fourth Sunday of Lent in honor of Mary. This day was expanded to honor all mothers.
In 1870 Julia Ward Howe started the American Mothers Day on June 2 to encourage peace, a reaction to the horrors of the American Civil War and the Franco-Prussian War.
As the result of work by Anna Jarvis, U.S. President Woodrow Wilson declared in 1914 that Mothers Day would be celebrated on the second Sunday in May.
