why do we fly flags at half mast

Flags are flown at half-mast (or half-staff) as a symbol of respect, mourning, or distress. This tradition, which began in the 17th century, is used to honor and commemorate individuals, such as government officials or members of the armed forces who have died, or to show solidarity and grief during tragic events affecting a community or nation. The flag is lowered to a position below the top of the flagpole, making space for an "invisible flag of death" above, symbolizing loss. This practice is common worldwide and often follows formal protocols depending on the country and occasion.
