Displaying the flag at half-staff, or half-mast, is a sign of mourning in the United States and other countries. When flown in this manner, it serves as a visible symbol of respect, grief, and remembrance for individuals or groups who have died or experienced a significant loss. This practice is usually ordered by the President of the United States, a state governor, or, in certain instances, by a local authority.
The act of lowering the flag is intended to provide a visual representation of mourning. The flag, normally flown at the peak of its staff, is purposefully lowered to a position halfway between the top and bottom, creating a striking image of solemnity. The reason for the lowering is typically related to the death of a prominent figure, a national tragedy, or a day of remembrance for fallen heroes. It acknowledges a collective sense of loss and unites citizens in honoring the deceased or those who have suffered. The act also serves to remind the public of the values, service, or sacrifice that the individual or group being honored represented.
