The German Reich is admitted to the League of Nations. It is also given a permanent seat on the most important organ of the organization, the council of the League of Nations. The main rival for this position, Poland, only receives a non-permanent seat on the council.

Over the course of the ceremonies marking Germany’s admission to the League of Nations, the German and French foreign ministers, Aristide Briand and Gustav Stresemann, meet in the French village of Thoiry. There they agree to comply with each other’s main foreign policy objectives. Stresemann pledges material support to stabilize the Franc, whereas Briand agrees to return the Saar Basin to Germany prematurely, to put an early end to the military control and occupation of the Rhineland and consents to a German-Belgian agreement on the return of Eupen Malmedy. However, the scope of the resolutions made in Thoiry is soon to be reduced due to the objections brought by the German and French governments. Despite this, the meeting in Thoiry is often still seen amongst scholars as the peak but also the endpoint of the Locarno policy.
