191. When was the Berlin Wall opened to everyone?

Answer options

1. 1987
2. 1989
3. 1992
4. 1995

Explanation

The de facto opening of the Berlin Wall occurred on 9 November 1989, triggered by SED Politburo member Günter Schabowski’s ambiguous announcement of a new travel regulation and the ensuing collapse of the GDR border regime at the crossings. In constitutional terms, this breakthrough paved the way for state unity via former Article 23 of the Basic Law (the GDR’s accession) and was legally consolidated by the Two Plus Four Treaty and the Unification Treaty. Only with accession on 3 October 1990 did fundamental rights such as freedom of movement (Article 11 GG) apply in the acceding territory, but the wall’s opening marked the irreversible political turning point. It was thus less a formal legal act than a revolutionary factual event subsequently regularized by law.
