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.
Coat of arms of Germany
It is a re-introduction of the coat of arms of the Weimar Republic (in use 1919–1935), which was adopted by the Federal Republic of Germany in 1950. The current official design is due to Karl-Tobias Schwab (1887–1967) and was originally introduced in 1928.
