While many celebrate the day, few are aware of the significance and history of the event which began as Decoration Day in the 1860s to honor soldiers who died in the Civil War. That war, which ended in the spring of 1865, claimed more lives than any conflict in U.S. history and required the establishment of the first national cemeteries in the country.
Memorial Day was originally celebrated on May 30 but in 1968, Congress approved the Uniform Monday Holiday Act, establishing the holiday would always fall on the last Monday in May.
