History Hustle Channel on YouTube explains the birth of the Free Territory of Trieste (FTT or TLT) in a video documentary.
The Free Territory of Trieste was the result between a dispute between the West and the East, between the United States and the Soviet Union, between Italy and Yugoslavia. Once part of the Austro-Hungarian Empire the Italians took it after World War One was over. However, after the Second World War the new Yugoslav state, led by Josip Broz Tito claimed it. British Gen. Sir William Morgan proposed a temporarily solution and the Morgan Line was created. The Tito–Stalin split (Yugoslav–Soviet split) put an end to the tensions. It was formalized much later in 1975 by the Treaty of Osimo. The history of Trieste is a forgotten episode in history of the Cold War.
