The Entente considered Hungary a partner in the defeated Dual Monarchy, and dashed the Hungarians' hopes with the delivery of successive diplomatic notes. Each demanded the surrender of more land to other ethnic groups. On 20 March 1919, the French head of the Entente mission in Budapest gave Károlyi a note delineating the final postwar boundaries, which the Hungarians found unacceptable. Károlyi and Prime Minister Dénes Berinkey were now in an impossible position. They knew accepting the French note would endanger the country's territorial integrity, but were in no position to reject it. In protest, Berinkey resigned.
