Third Europe
A "Third Europe" was the 1938 proposal of an alliance between the Second Polish Republic, the Kingdom of Romania, and the Kingdom of Hungary. It was proposed by Polish foreign minister Józef Beck, as a mutual defense pact against both Nazi Germany and the Soviet Union.
History
Intermarium
After the end of the First World War, Polish Chief of State Józef Piłsudski proposed the Intermarium, a country that would include the Baltic states, Poland, Czechoslovakia, Belarus, Ukraine, Romania, Hungary, and Yugoslavia. The country was meant to be a Federation that emulated the former Polish-Lithuanian Commonwealth, which had dissolved in 1795. Pilsudki also hoped that the plan could stop the aggression of the newly formed Russian Soviet Federative Socialist Republic by keeping it out of Lithuania, Belarus, and Ukraine.Pilsudski's next proposal was without Ukraine or Belarus, but with the addition of Finland, Bulgaria, and Greece. This Intermarium would not only stretch from the Baltic to the Black Seas, but also from the Arctic Ocean to the Mediterranean Sea. This plan also failed, as Poland was distrusted by Czechoslovakia and Lithuania. While Poland had good relations with some other countries, it had tensions with its neighbors rendering such a union impossible. Only a Polish-Romanian alliance emerged from the proposal, being established in 1921. In 1920, along with Yugoslavia and Romania, Czechoslovakia formed the Little Entente, which was supported by France.
Beck's proposal
Following Pilsudski's death in 1935, Polish Foreign Minister Józef Beck decided to create a plan for his own union between nations. He called his plan "Third Europe," an alliance between Poland, Romania, and Hungary. Beck hoped that the plan would prevent aggression by both Nazi Germany and the Soviet Union. Beck also hoped that the plan could allow him to become closer with the United Kingdom, as well as establish cooperation with Japan and Türkiye, among other powers. The concept became very prominent in the tense prewar years of 1937–1939. As observed by Marek Kornat, the principle of the Third Europe plan would be hard to reconstruct, as it was never implemented, and as Beck never gave an in-depth explanation of its principles.The proposal gained little traction before the onset of the Second World War due to the influence of Nazi Germany. Germany was the world's second largest economy and the third most populous in Europe. Germany had much more influence over Eastern Europe than either of the latter two powers due to its proximity to the region. Countries in Eastern Europe felt more inclined to follow Berlin's lead rather than Warsaw.
