German reunification

German reunification was the historic process of re-establishing Germany as a single sovereign state. This process began on November 9, 1989, and reached its conclusion on October 3, 1990. During this time, the German Democratic Republic (GDR) was dissolved. Its constituent federated states were integrated into the Federal Republic of Germany (FRG). This integration created the modern German nation we recognize today.

The date of October 3 was chosen as a national holiday. It is now celebrated annually as German Unity Day. On this same day, the divided city of Berlin was also reunified. Berlin eventually became the capital of the unified nation.

The roots of this division trace back to the end of World War II. After the unconditional surrender of German armed forces in 1945, the German Reich ceased to exist. There was no central government authority left in the country. The four Allied powers—the United States, the United Kingdom, France, and the Soviet Union—occupied Germany.

They divided the land into different occupation zones. The Potsdam Agreement in August 1945 helped organize these zones. This agreement also modified German borders. The country lost territories east of the Oder–Neisse line to Poland and the Soviet Union.

Two distinct states emerged from these occupation zones in 1949. The American, British, and French zones combined to form the Federal Republic of Germany (FRG) on May 23, 1949. This state, often called West Germany, was a liberal democracy. In October 1949, the Soviet-occupied zone became the German Democratic Republic (GDR).

This state, or East Germany, was a communist nation with a planned economy. The two countries lived side-by-side during the Cold War. Most borders between them were physically fortified and tightly controlled. West Germany joined NATO in 1955, while East Germany belonged to the Warsaw Pact.

Change began through a series of events known as the Peaceful Revolution. This movement included many protests by East German citizens. A major turning point occurred on May 2, 1989. On this date, Hungary removed its border fence with Austria. This created a hole in the Iron Curtain, which was the political boundary dividing East and West.

Thousands of East Germans used this opening to flee to West Germany via Hungary. This exodus was an irreversible movement that weakened the East German government. The political instability eventually led to the fall of the Berlin Wall on November 9, 1989.

Following the fall of the Wall, formal negotiations began to unite the two nations. The GDR held its first free elections on March 18, 1990. This led to the creation of a Unification Treaty between the two Germanies.

Other negotiations involved the four occupying powers. These talks resulted in the Treaty on the Final Settlement with Respect to Germany. This treaty granted full sovereignty to the reunified German state on March 15, 1991. Although sovereignty was granted then, the last Russian occupation troops did not leave Germany until August 31, 1994.

The legal structure of the new state is unique. The reunified Germany is not a successor state to the GDR. Instead, it is an enlarged continuation of the West German state.

This means the Federal Republic of Germany kept its existing international memberships. It retained its seats in the European Union, NATO, and the United Nations.

However, it had to relinquish membership in the Warsaw Pact. This was because only East Germany had been a member of that specific organization.

There has been much debate regarding the terminology used to describe these events. Some people call the process "German unity," which is the official term in the 1990 treaty. Others refer to it as "Die Wende," meaning "the turning point." Some scholars and political figures have even used the term "annexation" to describe the process. For example, in 2010, Matthias Platzeck referred to it as an "anschluss." However, others, including Mikhail Gorbachev, have rejected such labels. Regardless of the name, the events of 1989 and 1990 fundamentally reshaped the political landscape of Europe.
