When did Mother's Day become a holiday?

We know the holiday well - Mother's Day.  Falling in May, moms are wined and dined and recognized for their unending help and hard work.

I did a bit of research and found some interesting facts about the much loved holiday,

Mother's Day honors “the best mother who ever lived — your mother,” according to Anna Jarvis, who is widely credited with making the holiday an institution in the U.S. and across the globe.

The idea dates back to the 1850s when women in West Virginia organized into Mother’s Day work clubs that worked to reduce infant mortality and improve sanitary conditions for mothers and families. During the Civil War, these groups also cared for wounded soldiers from both sides.

After the war ended in 1865, women planned Mother’s Friendship Day picnics in an effort to bring Union and Confederate loyalists together, urging them to promote peace. “Battle Hymn of the Republic” writer Julia Ward Howe started a “Mother’s Peace Day" around this time, which encouraged mothers to support antiwar efforts on behalf of their sons' well being.

Many of the Mother's Day work club events were organized by Ann Jarvis, Anna's mother, who lost nine of her 13 children before they reached adulthood. After her death, Anna, held the first Mother’s Day observances in 1908 to honor her. Cities across the country adopted the trend, and in 1914 President Woodrow Wilson named the second Sunday in May a national holiday.

In 1914, Woodrow Wilson signed a proclamation designating Mother's Day, held on the second Sunday in May, as a national holiday to honor mothers. Although Jarvis was successful in founding Mother's Day, she became resentful of the commercialization of the holiday.
