Paris Peace Treaties, 1947

Italy lost the colonies of Italian Libya and Italian East Africa. The latter consisted of Italian Ethiopia, Italian Eritrea, and Italian Somaliland. Italy continued to govern the former Italian Somaliland as a UN trust territory until 1960. In the peace treaty, Italy recognized the independence of Albania (in personal union with the Italian monarchy after the Italian invasion of Albania in April 1939). Italy also lost its concession in Tianjin, which was turned over to China, and the Dodecanese Islands in the Aegean Sea were ceded to Greece.

Italy lost Istria: the provinces of Fiume, Zara, and most of Gorizia and Pola were ceded to Yugoslavia; the rest of Istria and the province of Trieste formed a new sovereign State (Free Territory of Trieste) divided in two administrative zones under a provisional government for which the United Nations Security Council was responsible.[2][3] In 1954, Italy incorporated the Province of Trieste (Zone A) and Yugoslavia incorporated the rest of Istria (Zone B). This was officially recognized with the Treaty of Osimo in 1975.

The villages of the Tende valley and La Brigue were ceded to France but Italian diplomats were able to maintain in place the Treaty of Turin (1860), according to which the French-Italian alpine border passes through the summit of Mont Blanc, despite French demands on the Aosta Valley. Anyhow the French Republic has never adopted any form of bilingualism in the towns of Briga and Tenda destining these municipalities to forced assimilation to French language.[4] The province of South Tyrol was also kept by Italy despite the territorial demands of Austria, largely thanks to the Gruber–De Gasperi Agreement signed some months before.

Finland was restored to its borders of 1 January 1941 (thus confirming its territorial losses after the Winter War of 1939-40), except for the former province of Petsamo, which was ceded to the Soviet Union. In Finland, the reparations and the dictated border adjustment were perceived as a major injustice and a betrayal by the Western powers, after the sympathy Finland had received from the West during the Soviet-initiated Winter War. However, this sympathy had been eroded by Finland's collaboration with Nazi Germany between 1941 and 1944. During this time, Finland not only recaptured territory it had lost in 1940, but continued its offensive deeper into Soviet lands, occupying a broad strip of Soviet territory. This prompted the United Kingdom to declare war on Finland in December 1941, further weakening political support in the West for the country. The Soviet Union's accessions of Finnish territory was based on the Moscow Armistice signed in Moscow on 19 September 1944 and resulted in an extension of the accessions in the Moscow Peace Treaty that ended the Winter War.

Hungary was restored to its borders before 1938. This meant restoring the southern border with Yugoslavia, as well as declaring the First and Second Vienna Awards null and void, cancelling Hungary's gains from Czechoslovakia and Romania. Furthermore, three villages (namely Horvátújfalu, Oroszvár, and Dunacsún) situated south of Bratislava were also transferred to Czechoslovakia, in order to form the so-called "Bratislava bridgehead".

Romania was restored to its borders of 1 January 1941, with the exception of the border with Hungary giving Northern Transylvania back to Romania. This confirmed the 1940 loss of Bessarabia and Northern Bukovina to the Soviet Union and the Treaty of Craiova, which returned Southern Dobruja to Bulgaria.

Bulgaria was restored to its borders of 1 January 1941, returning Vardar Macedonia to Yugoslavia and Eastern Macedonia and Western Thrace to Greece, but keeping Southern Dobruja per the Treaty of Craiova, leaving Bulgaria as the only former Axis power to keep territory that was gained during the Second World War.[5]
