Reactions to the 1926 Treaty of Berlin

From The Weimar Years: Rise and Fall 1918–1933, by Frank McDonough (Bloomsbury, 2023), Kindle pp. 397-400, 416:

Meanwhile, German foreign policy once again took centre stage. Stresemann had reacted to the delay in Germany’s admission to the League of Nations by taking a crucial step in improving relations with the Soviet Union. He wanted to keep friendship with the Soviet Union as a form of insurance policy, which might be used later to alter Germany’s eastern borders at the expense of Poland.

The pivot of German foreign policy towards the western Allies at Locarno had filled the Soviet government with feelings of deep anxiety. The delay in Germany joining the League offered the Soviets an ideal opportunity to make a dramatic diplomatic intervention. The Soviet Foreign Minister, Georgy Chicherin, told Stresemann that if the Locarno powers could not push through the entry of Germany to the League, then what could Germany expect of them when more serious matters were discussed? He felt a new Russo-German agreement would weaken the idea of the western Allies developing a common front against the Soviet Union. In response, Stresemann explained that he had always wanted to sign a new agreement with the Soviet Union, and had only delayed this due to a wish not to antagonise the members of the League of Nations during Germany’s application process.

On 24 April, the Treaty of Berlin (otherwise known as the German–Soviet Neutrality and Nonaggression Pact), was duly signed in Berlin by Gustav Stresemann for Germany and Nicolai Krestinski, the Soviet Ambassador, for the Soviet Union. It greatly strengthened the relationship between the two powers. The treaty consisted of just four brief articles: (1) The 1922 Treaty of Rapallo remained the basis of Russo-German relations, to which was added a promise by the two governments to maintain friendly relations with each other, and to promote a solution to all outstanding political and economic questions that concerned them both. (2) Germany and the Soviet Union pledged neutrality in the event of an attack on the other by a third party. (3) Neither party would join in any coalition for the purpose of an economic boycott on the other. (4) The duration of the treaty was set at five years. In 1931, it was renewed for three more years. To this, Stresemann added the additional assurance that if the League ever contemplated anti-Soviet sanctions or a military attack then he would do everything in his power to oppose it. The agreement was endorsed by a vote in the Reichstag on 10 June, with only three dissenting votes. On 29 June, the agreement was officially ratified by the German government. On 3 August, it was officially registered in the League of Nations.

In Germany, the Russo-German Treaty was received with universal acclaim. There was much greater public and political unanimity than there had ever been over the Dawes Plan, the Locarno Treaties and Germany’s proposed entry into the League of Nations. On 27 April, the Reichstag Committee on Foreign Affairs, usually the scene of bitter party disputes, gave the treaty its unanimous approval. The Nationalist DNVP believed the new agreement with the Soviet government would bring closer the return of Upper Silesia, Danzig and the Polish Corridor, for it was clear that a revision of Germany’s eastern frontiers required Soviet support, or at the least benevolent neutrality. Stresemann felt the agreement would quieten Soviet apprehension about the Locarno Treaties, maintain Germany’s good relations with Russia and appease the pro-Russian element on the Nationalist Right.

In the rest of Europe, the Treaty of Berlin caused a high degree of anxiety. The reaction in France, Poland, Czechoslovakia and Romania was wholly critical. The French press claimed the Treaty placed Germany’s entry into the League in jeopardy, and accused Stresemann of provocatively signing the German–Soviet Treaty to undermine the Geneva negotiations over Germany’s entry into the League of Nations. To the French government the treaty represented another Russo-German threat to Eastern Europe, and the French responded in June 1926 by signing an agreement with Romania, to add to its existing security agreements with Poland and Czechoslovakia. Aleksander Skrzyński, the Polish Foreign Minister, urged the Allies to examine what effect the new German–Soviet treaty would have on the obligations Germany would have to assume if it joined the League of Nations. In Britain, The Times adopted a surprisingly conciliatory tone, suggesting the agreement was not in conflict with the agreements made at Locarno, but the Daily Mail was much less charitable, arguing the Treaty of Berlin had raised suspicions about Germany’s true motives in moving closer to the Soviet Union at a time when it was supposedly aiming to become a loyal member of the League of Nations.

On 10 December, the Nobel Prize Committee awarded the Peace Prize for 1926 jointly to the Foreign Ministers of Germany and France, Gustav Stresemann and Aristide Briand, for their ‘critical roles in bringing about the Locarno Treaty and Franco-German reconciliation’, while at the same time awarding the Peace Prize for 1925, retrospectively and jointly, to Austen Chamberlain, the British Foreign Secretary, for his role in the signing of the Locarno Treaties and to the American financier Charles Dawes, for the central part he had played in brokering the financial restricting of Germany’s reparations under the Dawes Plan.
