Question:
Why are flags flown at half-staff?
Answer:
In the sixteenth century, ships would lower their flag halfway as a sign of submission during battle, and it was said they were flying at “halfmast.” On reaching port, the flag remained half-lowered in honour of those who had sacrificed their lives. In the seventeenth century the ritual moved to land, where it was said the flags were at “half-staff,” as a sign of respect for any individual who had died serving his country beyond the call of duty.
