Hungarian foreign policy from the collapse of the Austro-Hungarian Monarchy in November 1918 to the Peace Treaty of Trianon of June 1920 concentrated on maintaining Hungary's integrity and finding ways to break out of the international isolation in which the newly independent state found itself. Such were the aims of the regimes that followed each other in succession, and which are identified with the names of Mihály Károlyi, Béla Kun, and Miklós Horthy.
