Sport was one of the battlefields of the political and ideological conflicts that marked life in Trieste and the «Area A» of TLT, not only in relation to football and cycling but also in less popular disciplines. Starting to the recent works of Archambault, Sbetti and Zanetti Lorenzetti, this paper aims to deepen, in the broader context of the revival of Italian sport post-WWII, the reconstruction and conflicts of Trieste sport. In particular the focus is on Sports institutions (sometimes in a sutonomic and coordinated manner and some-times in a conflictual way): they have played an active role in defending of Italianness. To complete this paper, the auhors made use of secondary literature and direct sources. In particular the archives of Giulio Andreotti, of «Zone di Confine» Office, of Precidency of Council Minister, IOC and CONI as well as the most important national newspapers.
