Romanian Counter-offensive to the Tisza(1919)
Background
Béla Kun's government had launched a surprise offensive northward into Slovakia (May–June), temporarily rolling back Czech lines, which gave Hungary an inflated sense of military capability. When Romania counter-attacked in April, the Red Army's forces were overextended. The Allied Supreme Council pressured Romania to halt at the Tisza, but Romania used the pause to prepare the decisive July offensive.

The Battle
After the Hungarian Red Army's northern offensive into Slovakia stalled, Mărdarescu launched a coordinated counter-offensive that swept through Carei, Oradea, and Debrecen, driving Hungarian forces back to the Tisza by May 1.
The Romanian Counter-offensive to the Tisza in April 1919 was a strategic response to Hungarian attacks during the Hungarian–Romanian War. The operation resulted in a rapid Romanian advance that pushed the Hungarian Red Army across the Tisza River, establishing a new frontline.

A socialist government under the leadership of Gyula Peidl was installed in Budapest with the assistance of the Allied council, but its tenure was short-lived. The counter-revolutionary White House Fraternal Association attempted to install Archduke Joseph August of Austria as Hungary's head of state and István Friedrich as prime minister. However, the Allies would not accept a Habsburg as head of state in Hungary and so a new government was needed. Romania occupied all of Hungary except for an area around Lake Balaton. There, Admiral Miklós Horthy formed a militia with arms from Romania.
