Support: The Little Entente was an alliance formed in 1920 and 1921 by Czechoslovakia, Romania and the Kingdom of Serbs, Croats and Slovenes (Yugoslavia from 1929 on) with the purpose of common defense against Hungarian revisionism and the prospect of a Habsburg restoration in Austria or Hungary.

The first attempts seeking a mutual defense of the successor states of Austria-Hungary took place during the Paris Peace Conference of 1919.

The most remarkable and ardent proponent of the certain alliance binding the successor states was Edvard Beneš, the foreign minister of Czechoslovakia from 1918 to 1935.

[2] The obvious aim of his proposed alliance was to prevent the resurgence of Hungarian power and the restoration of the Habsburg monarchy, but its real purpose followed a much broader pattern.

Another interpretation is based on considerations of the new balance of power in Europe after World War I. France planned to contain possible German aggression by forming an arrangement with Germany's neighbours.

[5] A collective defense arrangement was signed in Belgrade on August 14, 1920, during a convention of Czechoslovakia and the Kingdom of Serbs, Croats and Slovenes.

Subsequently, Beneš suggested participation in the emerging alliance to Romania on August 17, 1920, but his offer was rejected by the Romanian government.

That was followed by the Hungarian reluctance to deprive Charles of his titles and the increasing danger of a military incursion of the Little Entente into Hungary.

The Kingdom of Serbs, Croats and Slovenes and Romania, however, were both agrarian countries that were uninterested in economic co-operation with the Soviet Union.

[25] The treaty was delivered by Ministers of Foreign Affairs of the member states: Bogoljub Jevtić for Yugoslavia, Nicolae Titulescu for Romania, and Edvard Beneš for Czechoslovakia.

The main instruments of collaboration were: The resurgence of German power after 1933 had gradually undermined French influence in the Little Entente countries.

To relieve that threat in 1934, Croatian Ustaše and possibly Italy, Hungary and Bulgaria[27] backed revolutionary Vlado Chernozemski, who assassinated King Alexander I of Yugoslavia and the French minister of foreign affairs, two leading proponents of the Little Entente.
