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.

On 26 February 1935 Hitler officially created the Luftwaffe with Hermann Göring as its Commander-in-Chief ("Oberbefehlshaber der Luftwaffe"). Late in 1935 a flag was instituted that consisted of a square of bright red silk. The flag was similar to some extent to that used before. The differences of the obverse were that now there was placed in the centre a gold swastika and instead of the four black swastikas four golden Luftwaffe eagles were added. The wings were left out. Moreover, the flag was edged on all four sides with a gold-braided border, which incorporated a row of 76 small gold swastikas all standing on their points. The reverse displayed a golden Luftwaffe eagle in the centre and four golden swastikas set in each corner of the flag. Suspended from the base of the silver laurel was a true representation of the "Pour le Mérite". When Göring was promoted to "Generalfeldmarschall" a pair of Luftwaffe field marshal's batons were added to the flag's reverse design and shown crossed above the "Pour le Mérite". The obverse remained the same as before. This alteration took place on 28 April 1938.
