Lies told by Hungary at Trianon

The Treaty signed at Trianon confirmed the recognition, by the major powers, of the Union of Transylvania and part of Banat with Romania, a deed already accomplished through the Act of Union on December 1st, 1918, but which had not been recognized by Hungary. The Treaty, with major significance for the history of Romania, was signed by 16 victorious Allied Powers in the First World War.
The delegation of the new Hungarian government arrived led by Count Albert Apponyi, presented to the Conference a voluminous body of evidence intended to support Hungarian claims, a method also used by Romania, Czechoslovakia, the Kingdom of Serbs, Croats, and Slovenes, Austria, and Italy.
The conclusions were that the Hungarians remained prisoners of the same exclusive mentality that existed before the outbreak of the war, and all the states affected by Hungary's claims protested solidly against the Hungarian argumentation.
