This article presents information concerning a European regional pact, formed during the interwar period – the Little Entente. The aim of the study is to highlight the advantages and disadvantages of an alliance between the countries of Central and Eastern Europe and the history of its creation. The influence that the Little Entente made on the history of Europe is very often overlooked. Though the alliance ultimately did not survive the strong pressure of the European powers, effective organisational structures and the successes of common foreign policy were a guideline for the integration of the Central and Eastern European countries in the future. The deliberate way in which foreign policy was conducted improved significantly alliance members position on the international area. The first part of the article relates to the historical background and describes both the historical and political environment of interwar Europe as well as indicates the most important moments during the process of the creation of an alliance. The next part describes links between the Little Entente and the French government. The main part of the study refers to the successes this alliance achieved as well as to the events that contributed to the collapse of this pact. This paper contains also a part connected with the heritage of the Little Entente. The last part of an article summarises the considerations of the content.
