# Moscow Treaty | European History 1945 to Present

## Definition

The Moscow Treaty was the 1970 agreement between West Germany and the Soviet Union that normalized relations during the Cold War. In European History 1945 to Present, it is a major example of Willy Brandt’s Ostpolitik.

## What It Is

The Moscow Treaty was a 1970 agreement between West Germany and the Soviet Union that marked a major shift in Cold War diplomacy. In this course, it shows West Germany moving away from rigid anti-communist isolation and toward Willy Brandt’s Ostpolitik, or Eastern Policy.

The treaty mattered because it accepted the political reality that existed after World War II. Instead of pretending Germany’s division or Europe’s new borders could be reversed immediately, West Germany agreed to work within the postwar order. That made the treaty feel controversial to some Germans, but it also opened the door to more stable relations with the Soviet bloc.

This was not just a symbolic handshake. The treaty supported normalization, meaning both sides were trying to make relations more regular and less hostile. That included a willingness to talk, cooperate, and reduce tension even while the Cold War continued. For Brandt’s government, this was part of a broader effort to increase trade and cultural contact with Eastern Europe.

The Moscow Treaty also signaled respect for sovereignty and peaceful conflict resolution. Those ideas sound routine, but in the Cold War they were a real change in tone. When countries have spent years treating each other as enemies, agreeing to solve disputes without force is a meaningful diplomatic step.

A common mistake is to treat the treaty as if it instantly ended the division of Germany. It did not. What it did was make later agreements easier, including deeper contact with East Germany and other Eastern Bloc states. In the bigger story of Europe since 1945, the Moscow Treaty is one of the clearest examples of détente in action, where former rivals chose negotiation over confrontation.

## Why It Matters

The Moscow Treaty matters because it shows how postwar Europe gradually moved from hard division toward managed cooperation. In the Cold War years, a lot of diplomacy was about drawing lines and protecting spheres of influence. This treaty shows West Germany trying a different approach, using dialogue instead of pressure.

It also helps explain Ostpolitik as more than a slogan. Brandt’s policy was built on the idea that acknowledging reality could create change later. By recognizing the postwar order and improving relations with the Soviet Union, West Germany set up the conditions for more treaties, more exchange, and less isolation.

For European History 1945 to Present, the treaty is a useful example of how diplomacy, ideology, and national identity overlap. Germans were still living with the consequences of World War II, and the treaty forced people to confront the divided map of Europe instead of imagining it away. That makes it a strong case study for détente, normalization, and the long path toward later European realignment.

## Connections

### Ostpolitik

The Moscow Treaty is one of the clearest results of Willy Brandt’s Ostpolitik. Ostpolitik was the broader strategy, while the treaty was one concrete agreement that put the strategy into practice. If you know Ostpolitik, the Moscow Treaty shows how the policy moved from idea to diplomacy.

### Normalization

This treaty is a textbook example of normalization because it tried to make relations between West Germany and the Soviet Union less tense and more practical. Instead of constant confrontation, both sides accepted limited cooperation, which is how many Cold War relationships gradually became more stable.

### Non-Aggression Pact

The Moscow Treaty is not the same thing as a non-aggression pact, but it shares the idea of reducing the chance of conflict. A non-aggression pact mainly promises no attack, while this treaty went further by supporting broader political acceptance and diplomatic contact.

### [Warsaw Treaty](/europe-since-1945/key-terms/warsaw-treaty)

The Moscow Treaty fits into the same diplomatic turn as the Warsaw Treaty. Together, these agreements show West Germany reaching out to Eastern Europe and accepting postwar borders. If you trace the sequence of Brandt’s diplomacy, these treaties work like steps in one larger policy.

## On the AP Exam

A quiz or short-answer prompt may ask you to identify the Moscow Treaty as part of Brandt’s Ostpolitik and explain what changed in West German diplomacy. For an essay, you might use it as evidence that Cold War Europe was not just about military standoff, but also about negotiated compromise and détente. If a question asks about the division of Germany or postwar borders, the treaty is a strong example of West Germany acknowledging reality rather than rejecting it. In timeline questions, place it in the early 1970s as part of the shift toward normalization with the Soviet bloc.

## Moscow Treaty vs Warsaw Treaty

These two treaties are easy to mix up because both are part of Ostpolitik and both involve West Germany reaching out to the East. The Moscow Treaty was signed with the Soviet Union, while the Warsaw Treaty was signed with Poland. In class, the difference usually matters when you are tracking which country West Germany recognized or negotiated with first.
