National POW/MIA Recognition Day is observed annually in September around a central theme to show commitment to full accountability to the families of captured service members and missing war heroes.
The terms POW and MIA mean prisoner of war and military personnel who went missing in action.
Many service members suffered as prisoners during the several wars that have happened throughout the history of the U.S. National POW/MIA Recognition Day was initiated as a day to commemorate the families of many of the tens of thousands of service members who never made it home.
The day was first observed in 1979 after Congress and the president passed a resolution to make it official following the demands of the families of 2,500 Vietnam War POW/MIAs who asked for accountability in finding their loved ones.it is also mostly associated with service members who were prisoners of war during the Vietnam War.
Regardless of where they are held in the country, National POW/MIA Recognition Day ceremonies share the common purpose of honoring those who were held captive and returned, as well as the memory of those who remain missing in service to the United States.
Until 1979, there was no formal day set aside for these important men and women and the first observance of POW/MIA day included a remembrance ceremony at the National Cathedral in Washington, D.C. Since then, the Pentagon is where the official observance happens, with other celebrations happening at military bases around the country and elsewhere.
