Flag of Germany
When Heinrich XI, Prince Reuss of Greiz was appointed by Joseph II, Holy Roman Emperor to rule the then-new Principality of Reuss-Greiz on 12 May 1778, the flag adopted by the "Fürstentum Reuß-Greiz" was the first-ever appearance of the black-red-gold tricolour in its modern arrangement in any sovereign state within what today comprises Germany – the Reuss elder line that ruled the principality used a flag whose proportions were close to a "nearly square"-shape 4:5 hoist/fly ratio, instead of the modern German flag's 3:5 figure.
Reichskriegsflagge
Designed personally by Adolf Hitler, this flag served the Heer and the Luftwaffe as their War Flag, and the Kriegsmarine as its War Ensign (the National Flag serving as Jack). This flag was hoisted daily in barracks operated by units of the "Wehrmacht" combined German military forces, and it had to be flown from a pole positioned near the barracks entrance, or failing this, near the guard room or staff building. New recruits in the latter part of World War II were sworn in on this flag (one recruit holding the flag and taking the oath on behalf of the entire recruit class with the recruits looking on as witnesses – before, this was done on the regimental colors).
The flag had to be formally hoisted every morning and lowered every evening. These hoisting and lowering ceremonies took the form of either an ordinary or a ceremonial flag parade. At the ordinary raising, the party consisted of the Orderly Officer of the Day, the guard, and one musician. At the ceremonial raising, one officer, one platoon of soldiers with rifles, the guard, the regimental band, and the corps of drums were all present.
