The origin of Mother’s Day as we know it took place in the early 1900s. A woman named Anna Jarvis started a campaign for an official holiday honoring mothers in 1905, the year her own mother died. The first larger-scale celebration of the holiday was in 1908, when Jarvis held a public memorial for her mother in her hometown of Grafton, West Virginia.
Over the next few years, Jarvis pushed to have the holiday officially recognized, and it was celebrated increasingly in more and more states around the U.S. Finally, in 1914, President Woodrow Wilson signed a proclamation making Mother’s Day an official holiday, to take place the second Sunday of May.
