The Free Territory of Trieste occupied a narrow strip of land around the Gulf of Trieste in the northern Adriatic Sea. It stretched from Duino in the north to Cittanova in the south, covering an area of approximately 386 square kilometers. The territory bordered post-war Italy to the north and Yugoslavia to the east and south. Rivers such as the Rižana, Dragonja, Timavo, Val Rosandra, and Mirna flowed through this small region. Its highest point was Monte Cocusso, while its most extreme points reached Medeazza in the north and Tarski Zaliv in the south. Savudrija marked the westernmost edge at 13° 29' longitude, and Gročana defined the eastern boundary at 13° 55'. This geographic configuration placed the territory directly between two emerging Cold War powers.
Ethnic Composition And Languages
Italian-speakers dominated urban settlements along the coast, but significant ethnic South Slavic minorities lived inland. By the end of World War I, Slovenes represented one-third of the population within the Trieste district. The countryside of the southern portion was mostly populated by ethnic Slovenes or Croats. Smaller communities included Istro-Romanians, Greeks, Albanians, and a sizeable Triestine Jewish community. The local Triestine dialect reflected this mix, based on Romance Venetian language with influences from ancient Rhaeto-Romance substrate. Some vocabulary came from German and Slovene sources, alongside loanwords from Greek. Variations of spoken Slovenian and Serbo-Croatian were largely dialectal, sharing words with Triestine and Istrian dialects. In the southernmost part, Croatian-based dialects were of the Chakavian type while Venetian-based Istrian remained common.
World War II Military Occupation
Italy joined World War II in 1940 as an Axis power alongside Nazi Germany. When the Fascist regime collapsed in September 1943, the territory fell under occupation by the German Wehrmacht armed forces. They made the city their capital for the Operational Zone of the Adriatic Littoral. Yugoslav Partisan units entered Trieste on the 1st of May 1945 after fighting in Opicina. The 2nd New Zealand Division arrived the next day and forced the surrender of approximately 2,000 German troops who had refused to capitulate to Yugoslav forces. An uneasy truce developed between New Zealand and Yugoslav troops until British General William Morgan proposed partitioning the area into separate military-administered zones. Yugoslav leader Josip Broz Tito agreed to this idea on the 23rd of May. A formal agreement signed in Duino on the 10th of June created the Morgan Line dividing the Julian March territory. Yugoslav troops withdrew to their designated area on the 12th of June 1945.
United Nations Administrative Framework
The United Nations Security Council approved Resolution 16 in January 1947 calling for a free state in Trieste. A permanent statute was supposed to become recognized under international law upon appointing an international governor approved by the Quatripartite Powers. On the 15th of September 1947, the peace treaty established the Free Territory of Trieste. Official languages included Italian and Slovene, with possible use of Serbo-Croatian south of the Dragonja River. Local government bodies were never formed, leaving administration to military authorities following the Morgan Line division. Zone A covered about 222 square kilometers with a population of 262,406 including Trieste itself, administered by British and American forces. Zone B spanned approximately 164 square kilometers with 71,000 residents, controlled by the Yugoslav army. Between October 1947 and March 1948, the Soviet Union rejected twelve successive nominees for civilian governor. The Tripartite Powers issued a note on the 20th of March 1948 recommending return to Italian sovereignty since no governor was ever appointed.
Economic Status Of The Free Port
The economy relied heavily on its ports, specifically the Free Port of Trieste and the Port of Koper. The first had a peculiar free zone status originating in 1719 and confirmed by the Treaty of Peace with Italy of 1947. This allowed transportation of goods inside the area without customs duties. Annex VIII to the Treaty stipulated that authorities shall not levy customs duties or charges other than those for services rendered. This status remains recognized by the international community and European Union today. The port facilitated regional trade during the territory's brief existence as an independent entity. Goods could move freely through the area under special provisions established decades earlier.
Demographic Shifts And Exodus
During the late 1940s, up to 40,000 people mostly Italians chose to leave Yugoslav Zone B and move to Italian Zone A. Some were intimidated into leaving while others simply preferred not to live in Yugoslavia. Within Yugoslavia, these people who left were referred to as optants per the right of option provided in the Treaty of Peace with Italy. They called themselves exiles. About 14,000 Italians chose to remain in the Yugoslav zone. The population of the Free Territory was approximately 370,000 in 1949 according to Allied Military Government estimates published that year. Zone A contained about 239,200 ethnic Italians and 63,000 ethnic Slovenes at that time. Contemporary Italian sources estimated Zone B had between 36,000 to 55,000 Italians and 12,000 to 17,000 Slovenes and Croats.
Dissolution And Final Settlement
On the 5th of October 1954, the London Memorandum was signed by ministers from the United States, United Kingdom, Italy, and Yugoslavia. This memorandum did not change the de jure status but dissolved the territory de facto. After withdrawal of Allied military troops by the 24th of October 1954, Italy assumed civil administration of Zone A on the 26th of October 1954. Italian General de Renzi arrived in Trieste at 12:00 to formalize the handover. Zone B remained under Yugoslavian administration while Yugoslavia took control of several villages previously located in Zone A including Plavje, Spodnje Škofije, Elerji, Hrvatini, Kolomban, Cerej, Premančan, Barizoni, and Socerb. The demarcation line continued as a frontier dispute until November 1975 when the bilateral Treaty of Osimo ended any current or future claims. This treaty was ratified in 1977, resolving the border issue twenty years after initial dissolution.
