The South Tyrol Question between conflict and diplomacy (1918–1992): Relations between Italy, Austria and South Tyrol on the path towards pacification

This thesis reconstructs the South Tyrol (Alto Adige/Südtirol) dispute as a protracted diplomatic controversy, extending across several decades, in which bilateral negotiations, United Nations involvement, and domestic political developments evolved in constant interaction. Rather than treating autonomy as a purely internal constitutional issue, the study approaches the South Tyrolean question as an international problem shaped by diplomatic exchanges, parliamentary debates, and changing international contexts. The central argument is that the resolution of the dispute emerged gradually through negotiated procedures and internationally recognized stages, rather than through a single decisive agreement. The research is based on the analysis of primary sources, including diplomatic documentation (memoranda, notes verbales, bilateral communiqués), United Nations records, and the verbatim proceedings of the Italian and Austrian Parliaments. These materials are used to reconstruct the positions of the parties, the language of negotiation, and the procedural frameworks within which the controversy was managed. Chapter 1 traces the historical origins of the South Tyrol question from annexation to the post-war settlement, focusing on the emergence of minority protection as a diplomatic issue in post-war Europe. Particular attention is devoted to the De Gasperi–Gruber Agreement of 1946, analysed as a diplomatic compromise that established an international reference point while deliberately leaving open key questions concerning the scope and implementation of autonomy. This ambiguity would later shape bilateral negotiations and Austria’s recourse to the United Nations. Chapter 2 examines the period between 1948 and 1972 as a phase of unresolved conflict, during which the First Autonomy Statute and the regional framework of Trentino–Alto Adige/Südtirol failed to stabilize relations between Italy, Austria, and the South Tyrolean population. Through parliamentary debates and diplomatic correspondence, the chapter shows how implementation delays and recurring central-state interventions eroded confidence in the autonomy arrangement and facilitated its gradual internationalization. The thesis then reconstructs the dispute’s passage to the United Nations, analysing Austria’s initiatives and the adoption of General Assembly Resolutions 1497 (XV) and 1661 (XVI). It highlights the UN’s role as a procedural diplomatic arena that encouraged the continuation of bilateral negotiations and framed the controversy as a question of treaty interpretation and implementation. Episodes of political violence and terrorism are examined as a contextual factor influencing diplomatic rhetoric, without displacing negotiation as the primary path to settlement. Within this framework, the thesis examines the work of the Commission of Nineteen as a preparatory phase translating diplomatic commitments and domestic constraints into concrete proposals. It then reconstructs the elaboration of the “Package” as the key political compromise redirecting the dispute toward a negotiated settlement, accompanied by an operational calendar that structured implementation over time and enabled international verification. Chapter 3 focuses on the final phase of the settlement, examining the implementation of the Package through implementing norms and the gradual transfer of competences. It analyses how these steps enabled Austria’s issuance of the quietanza liberatoria and the subsequent communication to the United Nations, interpreted as the formal conclusion of a long diplomatic process. By foregrounding diplomatic documentation and parliamentary records, this thesis presents the South Tyrol settlement as a historically contingent process of conflict management in which international diplomacy, rather than coercive intervention or adjudication, played the decisive role.
