204. How did the Federal Republic of Germany and the GDR become a single state?
Official German wording
Wie wurden die Bundesrepublik Deutschland und die DDR zu einem Staat?
Answer options
Correct answer
The five present eastern federal states acceded to the Federal Republic of Germany.
Explanation
German unity occurred on 3 October 1990 by the GDR’s accession under Article 23 of the Basic Law (old version), after the GDR reconstituted its Länder and concluded the Unification Treaty. In international law, the Federal Republic continued as the same state; the GDR ceased to exist and its territory was integrated—this was neither occupation nor annexation. The Two Plus Four Treaty settled the external dimension (full sovereignty, borders), while the Unification Treaty governed domestic legal harmonization and the continued application or transfer of East German law. A constituent refounding under Article 146 did not occur; instead, the Basic Law was amended and extended to the acceding Länder.
