, Poland) and nearly 200 surrounding towns and villages that had a predominantly German population. It was created on 15 November 1920 in accordance with the 1919 Treaty of Versailles that ended World War I, which excluded the area from Weimar Germany and the new Second Polish Republic. The Free City had a customs union with Poland. During the allied occupation of Vienna between 1945 and 1955, a small international zone in the historical city centre was governed in rotation by American, British, French, and Soviet troops. During the Cold War, the Friedrichstraße station was served by West Berlin S-Bahn and U-Bahn trains despite being located entirely in East Berlin. The station also served as a border crossing between West Berlin and East Germany. Under the 1947 United Nations Partition Plan for Palestine, the city of Jerusalem was supposed to become an international corpus separatum. This was never implemented; the city was the scene of fierce fighting in the 1948 war which culminated in its partition between West Jerusalem (Israel) and East Jerusalem (Jordan). In the 1967 war, East Jerusalem was captured and unilaterally annexed by Israel, in a move that has not been recognised by the international community. The idea of an international zone in Jerusalem, encompassing at least the highly sensitive Old City, continues to feature in many proposals to resolve the Israeli-Palestinian conflict. The Free Territory of Trieste was an international zone around the Adriatic Sea port of Trieste, under direct responsibility of the United Nations Security Council. The area was established on 10 February 1947 by a protocol of the Treaty of Peace with Italy in order to accommodate an ethnically and culturally mixed population in a neutral environment free from the rule of either Italy or Yugoslavia, which made competing claims on the territory. The Free Territory was de facto given to its two neighbours in 1954 and this was formalised much later by the bilateral Treaty of Osimo of 1975, ratified in 1977.
