In Germany, flying flags for mourning is ordered by the federal or state interior ministers in the event of national mourning; in Austria by the Federal Chancellor. It may apply on certain commemorative days, such as the national day of mourning, on the death of an important statesman, or in remembrance of tragic events such as the terrorist attacks of 11 September 2001.
Procedure
Mourning is usually marked by flying flags at half-mast. In this case the flags concerned – but not banners – are positioned on public buildings not at the top of the
flagpole but (depending on the length of the flag) slightly above the middle of the pole. The correct way to fly a flag at half-mast is to raise it first to the top of the pole, and only then to the half-mast position, where it
is then lowered. Conversely, when taking it down, the flag is first raised all the way to the top again and only then removed.
As an alternative to flying at half-mast, a mourning ribbon may be used on state banners; in that case the banner is positioned at the top of the pole.
History
The practice of flying flags at half-mast originates from naval battles between sailing ships. It was not only the flag of the defeated ship that was hauled down, but first of all the topmost sail. The enemy later also had to lower their own flag halfway, and in its place the victor's flag was raised as a visible sign to all.
From this ritual later arose the custom of lowering a flag as a sign of respect for persons of higher rank. Ships also greeted one another by dipping their flags. The original purpose – to make room for another flag – was forgotten. Today, flying a flag at half-mast is a mark of respect for the dead (the space at the top of the pole is for the invisible flag of death).
Special features
The flag of Saudi Arabia is the only flag that is never flown at half-mast. The reason is that it bears the Shahada, the Islamic declaration of faith.
