The Treaty on the Final Settlement with Respect to Germany

Overview

On October 10, 1991, the Treaty on the Final Settlement with Respect to Germany, often referred to as the “Two Plus Four Agreement,” officially came into effect. This treaty was a pivotal moment in European history as it laid the groundwork for the reunification of Germany, which had been divided since the end of World War II.

Background

Following World War II, Germany was divided into East Germany (the German Democratic Republic) and West Germany (the Federal Republic of Germany), with Berlin similarly split into East and West. This division was emblematic of the broader Cold War tensions between the Soviet Union and the Western Allies, primarily the United States, the United Kingdom, and France.

The fall of the Berlin Wall on November 9, 1989, marked the beginning of the end for the division of Germany. This event set off a series of political changes that made reunification possible. The collapse of communist regimes across Eastern Europe and the weakening of Soviet influence under Mikhail Gorbachev’s policies of glasnost and perestroika further paved the way for change.

The Treaty

The Two Plus Four Agreement was negotiated between the two German states and the four Allied powers that occupied Germany after World War II: the United States, the Soviet Union, the United Kingdom, and France. The treaty was signed on September 12, 1990, in Moscow.

Key Provisions

  1. Sovereignty: The treaty restored full sovereignty to Germany, allowing it to make its own decisions regarding foreign and domestic policy without external interference.

  2. Borders: It confirmed Germany’s borders, particularly the Oder-Neisse line, which marked the boundary with Poland, thus ensuring peaceful relations with its neighbors.

  3. Military Restrictions: Germany agreed to limit its armed forces to 370,000 personnel and renounced the production and possession of nuclear, biological, and chemical weapons.

  4. Allied Forces: The treaty stipulated the withdrawal of Soviet troops from East Germany by the end of 1994 and the end of Allied occupation rights in Berlin.

  5. NATO Membership: It was agreed that a unified Germany would remain a member of NATO, which was a significant point of negotiation, especially for the Soviet Union.

Reunification

The treaty’s implementation on October 10, 1991, was a formal recognition of the reunification that had already taken place on October 3, 1990, when East and West Germany officially became one nation. This reunification was a momentous event, symbolizing the end of Cold War divisions in Europe.

Aftermath and Significance

The reunification of Germany had profound implications for Europe and the world:

  • European Integration: It accelerated the process of European integration, leading to the strengthening of the European Union.

  • NATO and Security: Germany’s continued membership in NATO helped stabilize the security landscape in Europe.

  • Economic Impact: The reunification posed significant economic challenges, as the integration of the two economies required substantial investment and restructuring.

  • Symbolic Victory: It marked a symbolic victory for democratic ideals over communist regimes, influencing political changes in other Eastern European countries.

The Treaty on the Final Settlement with Respect to Germany remains a landmark in diplomatic history, representing a peaceful resolution to decades of division and conflict.
