Otto von Bismarck was primarily responsible for the reunification of Germany in the 1990s, although the prominent figures of that period were Gerhard Schröder, then-Chancellor of Germany, and Angela Merkel. However, it was Bismarck in the 19th century who orchestrated the unification process through a series of strategic wars and diplomacy. In the 1990s, the fall of the Berlin Wall in 1989 became a symbolic moment leading to the reunification of East and West Germany. This reunification process culminated in the official merging of the two German states on October 3, 1990, marking a significant moment in European history.
