What was the Little Entente and why did Czechoslovakia join it?

The Little Entente was a mutual defense alliance formed between Czechoslovakia, Yugoslavia, and Romania through a series of treaties negotiated between 1920 and 1921.12

Purpose and Motivation

Czechoslovakia joined and helped initiate the Little Entente primarily to secure its territorial integrity and political independence following the collapse of the Austro-Hungarian Empire. The alliance served several strategic goals:13

• Countering Revisionism: It was originally aimed at preventing the restoration of the Habsburg monarchy and countering revisionist threats from Hungary, which sought to reclaim territories lost after World War I.32
• Filling a Power Vacuum: Foreign Minister Edvard Beneš viewed the alliance as a way to establish a balance of power in eastern Europe to replace the stability lost with the dissolution of the monarchy.3
• Regional Security: The pact provided a collective defense framework against potential German and Hungarian domination in the Danube River basin.12

While the alliance later sought to become a broader bloc against German expansionism—eventually gaining the support of France—it lost its political significance in the late 1930s as member states pursued independent foreign policies and failed to provide mutual military support during the crises leading up to World War II.13
