The Second World War in Istria
The Second World War came to Istria whilst it was under Italian rule, to which it belonged after the end of the First World War and the collapse of Austria-Hungary, its previous ruler. The period of Italian rule in Istria, from 1920 until 1943, escalated during the fascist regime. It was characterised by bans, persecutions, humiliations and transformations that had reflected negatively on the identity and sustainability of Croats (and Slovenes) in Istria. Therefore, many emigrated, together with the anti-fascist Istrians, most often to the then Yugoslavia. It was, in fact, the first great wave of emigration due to the totalitarian regimes of the 20th century.
After twenty months of war and German occupation, in the spring of 1945, the Second World War in Istria ended. The region became the subject of a dispute because of the eastern border of Italy, i.e. the western border of Slovenia and Croatia.
From 1945 to 1947, pending the decisions of the Peace Treaty which determined the fate of Istria, the entire territory of the Julian March was temporarily divided into Zone “A” (Trieste, Gorizia and Pula), under the control of the Anglo-Americans, and Zone “B” (the area east of the demarcation line, or the Morgan Line) under the Yugoslav military administration.
The visit of the Inter-Allied Commission in the spring of 1946, sent to the disputed areas to determine the national and economic situation on the ground, and the wait for the Peace Conference to be held, contributed to the strengthening of the conflict between the pro-Yugoslav and pro-Italian fronts. Namely, the logic of territoriality that led to the drawing of border lines on the ground was inevitably reflected in the social fabric of Istria, with disastrous consequences for the population of these areas.
Therefore, with the adoption of the French proposal for a new border between Italy and Yugoslavia, Rijeka and the greater part of Istria went to Yugoslavia, whilst for northwest Istria and Trieste an agreement was not reached between the victorious powers and it was decided to establish the Free Territory of Trieste, divided into Zone “A” and Zone “B”, the first under the administration of Anglo-Americans, and the second Yugoslav. The Peace Treaty was signed in Paris on 10th February 1947, however, the formal transfer of sovereignty took place on 15th September 1947. It was only in 1954, with the signing of the Memorandum of Understanding in London, that the fate of the never-created Free Territory of Trieste – Zone “A” was settled, and it passed over to the administration of Italy, and Zone “B” to Yugoslavia. The situation was only definitively resolved in 1975 with the Osimo Treaties.
1945 was also a year of extreme choices for many Istrians who went into exile.
