In the years following the bitter Civil War, a former Union general took a holiday originated by former Confederates and helped spread it across the entire country.
The holiday was Memorial Day, and the 2018 commemoration on May 28 marks the 150th anniversary of its official nationwide observance. The annual commemoration was born in the former Confederate States in 1866 and adopted by the United States in 1868. It is a holiday in which the nation honors its military dead.
Gen. John A. Logan, who headed the largest Union veterans fraternity at that time, the Grand Army of the Republic, is usually credited as being the originator of the holiday.
