On May 5, 1868, the Grand Army of the Republic established Memorial Day or Decoration Day as the national day to decorate the graves of the Civil War soldiers with flowers.

Even before this declaration, local observances for these war dead were being held at various places. In Columbus, Miss., a group of women visited a cemetery on April 25 1866, to decorate the graves of Confederate soldiers and the Union soldiers whop fell at the battle of Siloh. Many cities in the North and the South claim to be the first to celebrate Memorial Day in 1866 but Congress and President Lyndon Johnson officially declared Waterloo in New York as the 'birthplace' of Memorial Day in 1966. It was said that on May 5, 1866, a ceremony was held here to honor local soldiers and sailors who fought in the Civil War, businesses were closed for the day and residents furled flags at half-mast. It was said to be the first formal, community-wide and regular event.
In 1971, Memorial Day was declared a national holiday by the Congress, who designated the last Monday in May as the day for its observance.
