The very basis of the relationships between Italy and the new born Czechoslovak state was constituted by military and diplomatic activities, leading to formation of military corps as the first manifestation of the state not having yet denomination no its own geographical frontiers. The article proposes to show how the attitude of Italy towards constitution of the independent Czechoslovakia was strictly conditioned by seeing the new state as an ally in the Adriatic problem and by its support of Italyʼs territorial demands on the Dalmatia and Istria coast. We try to point out, relaying on the information and contents of the Italian diplomatic correspondence, how such a support was abandoned as a consequence of Czechoslovak foreign politics choices made in the immediate after World War I period. In this way, we were able to reconstruct in a more detailed way a chapter of the Italian-Czechoslovak relations not fully examined in the contemporary period.
