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.
Flag of Europe
On 25 September 1953, the Consultative Assembly of the Council of Europe recommended that a blue flag with fifteen gold stars be adopted as an emblem for the organisation, the number fifteen reflecting the number of states of the Council of Europe. West Germany objected to the fifteen-star design, as one of the members was Saar Protectorate, and to have its own star would imply sovereignty for the region. The Committee of Ministers (the Council's main decision making body) agreed with the Assembly that the flag should be a circle of stars, but opted for a fixed number of twelve stars, "representing perfection and entirety". The Parliamentary Assembly of the Council of Europe on 25 October 1955 agreed to this. Paul M. G. Lévy drew up the exact design of the new flag. Officially adopted on 8 December 1955, the flag was unveiled at the Château de la Muette in Paris on 13 December 1955.
