Hungary was invited to the Paris Peace Conference on the basis of the decision of the Supreme Council of the Peace Conference. Budapest did not agree with the peace conditions but it sent its delegation to the Peace Conference without any delay.
The draft peace conditions were handed over to Hungary on the 15 January and the final peace conditions on the 5 or more formally 6 May 1920. The Hungarian peace delegation lead by Count Apponyi finally admitted that the Peace Treaty was delicate for them both from domestic and from foreign political perspective and resigned.
Despite it, the representatives of the Hungarian government signed the treaty on 4 June 1920. The main moment in the decision-making of the Hungarian political leaders was the new conception of French foreign policy.
The secret French-Hungarian political negotiations were established and Budapest hoped that it would lead to additional revision of the territorial provisions of the Peace Treaty after its signature.
