The Free Territory of Trieste was established by demand of the United Nations Security Council through its Resolution 16 of January 1947, under Article 24 of the UN charter, calling for the creation of a free state in Trieste and the region surrounding it. A permanent statute codifying its provisions was to become recognized under international law upon the appointment of an international governor approved by the Quatripartite Powers. On 15 September 1947, the peace treaty between the United Nations and Italy was ratified, establishing the Free Territory of Trieste.
