A single German citizenship was created, with equal treatment of citizens within each state guaranteed (Article 3). However, until 1913, a person would hold the citizenship of the Empire as a result of holding the citizenship of one of the States. Therefore, initially, the criteria for becoming a citizen (the rules of acquisition of citizenship by descent, birth or naturalization), were laid down by the separate laws of the individual States. Only on 22 July 1913 was a common uniform Nationality Law for the Empire – the Nationality Law of the German Empire and States (Reichs- und Staatsangehörigkeitsgesetz, shorthand: RuStAG) – adopted.

As West Germany was reorganised and gained independence from its occupiers, the German Democratic Republic was established in East Germany in 1949. The creation of the two states solidified the 1945 division of Germany.  On 10 March 1952, (in what would become known as the " Stalin Note ") Stalin put forth a proposal to reunify Germany with a policy of neutrality, with no conditions on economic policies and with guarantees for "the rights of man and basic freedoms, including freedom of speech, press, religious persuasion, political conviction, and assembly" and free activity of democratic parties and organizations.  This was turned down; reunification was not a priority for the leadership of West Germany, and the NATO powers declined the proposal, asserting that Germany should be able to join NATO and that such a negotiation with the Soviet Union would be seen as a capitulation. There have been several debates about whether a real chance for reunification had been missed in 1952.
