Memorial Day is a United States federal holiday observed on the last Monday of May (May 31 in 2010). Formerly known as Decoration Day, it commemorates U.S. soldiers who died while in the military service.[1] First enacted to honor Union soldiers of the American Civil War – it is celebrated near the day of reunification after the Civil War – it was extended after World War I to honor Americans who have died in all wars.
Arlington National Cemetery in Arlington County, Virginia is a military cemetery in the United States of America, established during the American Civil War on the grounds of Arlington House, formerly the estate of the family of Confederate general Robert E. Lee's wife Mary Anna (Custis) Lee, a descendant of Martha Washington. The cemetery is situated directly across the Potomac River from the Lincoln Memorial in Washington, D.C. and near The Pentagon.
