The Treaty of Trianon was the peace settlement that the victors of World War I imposed on Hungary after the war. The treaty's severity was unprecedented in modern European history. By dismembering the multi-ethnic “historic Kingdom of Hungary” the treaty left Hungarians less than a third of their former territory and transferred 3.3 million of them to neighboring states. Not surprisingly, Trianon came as a shock to the Hungarian people and constituted an enduring blow to the Magyar national psyche. During the next quarter century, Hungarians were obsessed with the idea of reversing this dictum and the primary objective of their foreign policies was the creation of international conditions in which the revision of Trianon could become possible. For this purpose the regime in Budapest sought allies, as this aim could be attained only with outside help. By the first half of 1941 this search had led to Hungary's entanglement in an alliance with Nazi Germany. Once Hungary became a partner in the Nazi war, the danger emerged that if the country did not toe the German line, Hitler would reverse the frontier adjustments that he had rendered earlier in Hungary's favor. Already during the late summer of 1941 some of Hungary's statesmen realized that the Third Reich might not win the war, but their plans to limit their contribution to the Nazi war effort and to prepare for defection from the Axis were frustrated by the fear that, if they abandoned or weakened the alliance with Berlin, no more “lost” Hungarian lands could be regained and lands already recovered might be forfeited again.
