As we all know, the countries participating in the First World War were divided into two camps: one was the Allied camp led by Britain, France, Russia, and the United States; The other was the Allied camp led by Germany and Austria-Hungary. After the end of World War I, the two camps were disbanded. What is less well known is that there were also "little Entente powers" between World War I and World War II.
After the end of World War I, the victorious powers established the "Versailles-Washington" system. The dominant countries of the "Versailles-Washington" system were Britain and France, and Germany, Austria, Hungary (one of the two main bodies of the Austro-Hungarian Empire) and other defeated countries in World War I were all the objects of defense of the "Versailles-Washington" system. France, in particular, which wants to maintain its hegemony over the Continent, is particularly guarding against the resurgence of the defeated countries.
With the collapse of the Austro-Hungarian Empire, many small states emerged in southeastern Europe, and they were the best targets for expansion for the resurgence of defeated countries such as Germany and Austria. France, on the other hand, is located in Western Europe and is somewhat "out of reach" for Germany's expansion in Eastern Europe. France supported Czechoslovakia, Romania, and Yugoslavia in forming a political-military alliance to curb the expansion of Germany and Austria.
On August 14, 1920, Czechoslovakia and Yugoslavia signed the Treaty of Defensive Alliance between Czechoslovakia and Serbo-Croat-Slovenia. On April 23, 1921, Czechoslovakia and Romania signed the Treaty of Alliance between Czechoslovakia and Romania. On 7 June 1921, Romania and Yugoslavia signed the Treaty of Defensive Alliance between Romania and Serbo-Serbo-Croat-Slovenia.
In September 1920, Czechoslovakia's then-foreign minister, Beneš, proposed that the alliance of Czechoslovakia, Romania, and Yugoslavia be named "Little Entente" to show the intention of preserving the fruits of victory in World War I. In February 1933, Czechoslovakia, Romania and Yugoslavia signed the Convention on the Organization of the Little Entente, and the "Little Entente", an international organization formed by the three countries, was formally established.
However, because France, the largest backer of the "Little Entente", pursued an "appeasement policy" before World War II, the foundation of the "Little Entente" was shaken. In 1938, with Czechoslovakia being completely betrayed by Britain and France in the "Munich Conspiracy", the "Little Entente" survived in name only. After Czechoslovakia was annexed by Nazi Germany in 1939, the Little Entente disintegrated.
