Free Territory of Trieste

The Free Territory of Trieste was an independent territory in Southern Europe between Italy and Yugoslavia, facing the north part of the Adriatic Sea, under direct responsibility of the United Nations Security Council in the aftermath of World War II. It existed for seven years. The territory was established on 10 February 1947, by a protocol of the Treaty of Peace with Italy, to accommodate an ethnically and culturally mixed population in a neutral independent country.
