From the beginning, the year 1926 was oversaturated by the 'spirit of Locarno'. However, some serious proofs awaited the Locarno understanding. There were many hopes laid on the Locarno treaties. These treaties could have come into power only in connection with the German membership in the League of Nations. The process of Germany's admission met with several solemn complications. These complications jeopardized even the Locarno understanding and revealed the long lasting problems of the Geneva organization. Germany's admission represented an important change in international relations. The Czechoslovak minister of foreign affaires counted with the German membership in the League of Nations. He expected increased security in the region from this step. Locarno and Germany's admission closed one period of the post-war history. These two events had a great impact on the Czechoslovak position in the political arena, and also on Czechoslovak-German relations.
