Anna Marie Jarvis, shown here, got Mother's Day officially proclaimed. Her mother, Ann Jarvis, a young Appalachian homemaker, began organizing “Mother's Work Days” in 1858 to improve sanitation and avert deaths from disease-bearing insects and polluted water. When Ann Jarvis died in 1905, her daughter, Anna, began a campaign to memorialize her mother’s lifelong activism that culminated in 1914 when Congress passed a Mother's Day resolution.

The first official Mother's Day was May 9, 1914, according to Library of Congress records.

President Woodrow Wilson proclaimed the day to be one for expressing public “reverence” for mothers.

West Virginia native Anna Jarvis is considered to be the driving force behind the campaign, which she developed in memory of her mother Anna Reeves Jarvis.

Mother Jarvis established the Mothers Day Work Clubs in the 1850s.

Among other things, these clubs nursed soldiers on both sides of the Civil War, advocated for better sanitation and worked toward improving individual health.

In today's world, mothers are an evolving demographic.

Roughly 66% of the 23.5 million women who worked in 2018 with children under 18 worked full-time, according the U.S. Census Bureau.

About 40% of all working mothers in 2018 worked in education, health care or social assistance.
