In 1940 ethnic disturbances between Hungarians and Romanians continued after some incidents following the entrance of the Hungarian Army, culminating in massacres at Treznea and Ip in the first two weeks approximately 1000 Romanians perished. Five days after the Second Vienna Award, on September 5 1940, at 7.00, the first Hungarian military unit crossed the border at Sighetul Marmației. Two Hungarian armies entered the territory of annexed Transylvania: First Army - with a force of 208,000 soldiers. It operated in the northeastern part of Transylvania. Second Army - with a staff of 102,000 soldiers. It operated in the Oradea - Cluj area. On the first day, the main occupied cities were Carei, Satu Mare, Sighetul Marmației and Ocna Șugatag. Nine stages of progress were established, each over a distance of 40-80 kilometers. The last localities taken over, on September 13 1940, were Sfântu Gheorghe and Târgu Secuiesc.

The Hungarian army was greeted enthusiastically by the majority of the Hungarian population, which was documented in detail in the 1940 films, with the parade of military units, as well as Horthy riding on gray horse, marching through the main cities of Northern Transylvania. After some ethnic Hungarian groups considered unreliable or insecure were sacked/expelled from Southern Transylvania, the Hungarian officials also regularly expelled some Romanian groups from Northern Transylvania. Also, many Hungarians and Romanians fled or chose to opt between the two countries. There was a mass exodus; over 100,000 people on both sides of the ethnic and political borders relocated. This continued until 1944. On March 19, 1944, following the occupation of Hungary by the Nazi Germany army through Operation Margarethe, Northern Transylvania came under German military occupation. Like the Jews living in Hungary, most of the Jews in Northern Transylvania (about 150,000) were sent to concentration camps during World War II, a move that was facilitated by local military and civilians. Following several decrees of the Hungarian government and high-level consultations at a meeting on April 26 with László Endre in Szatmárnémeti (now Satu Mare), the deportation of the Jews was decided.
