République démocratique hongroise
After the Romanian Army advanced beyond this cease-fire line, the Entente powers asked Hungary (Vix Note) to acknowledge the new Romanian territorial gains by a new line set along the Tisza river. Unable to reject these terms and unwilling to accept them, the leaders of the Hungarian Democratic Republic resigned and the Communists seized power. In spite of the country being under Allied blockade, the Hungarian Soviet Republic was formed and the Hungarian Red Army was rapidly set up. This army was initially successful against the Czechoslovak Legions, due to covert food and arms aid from Italy. This made it possible for Hungary to reach nearly the former Galician (Polish) border, thus separating the Czechoslovak and Romanian troops from each other.
