The lowering of the flag to half-staff, often referred to as half-mast when displayed on a ship or naval vessel, serves as a nationally recognized symbol of mourning. This practice is implemented as a sign of respect, remembrance, and grief, generally following the passing of prominent figures or in response to significant national tragedies.
The display of the flag at half-staff is a powerful visual representation of collective sorrow and unity. It allows the nation, state, or community to collectively acknowledge a loss, pay tribute to the deceased, and offer condolences to those affected. Historically, lowering the flag was believed to make room for the “invisible flag of death” to fly above it. Over time, it evolved into its modern symbolic meaning.
