Hungary–Romania relations
During World War II, Hungary and Romania became allies and participated in the war against the Soviet Union. But after the coup on 23 August 1944 Romania switched sides and fought against Hungary. Consequently, Soviet and Romanian troops invaded Hungary, occupied Northern Transylvania by October 1944 and re-established the Romanian administration in the region in March 1945. The 1947 Treaty of Paris reaffirmed the borders between Romania and Hungary as originally defined in Treaty of Trianon 27 years earlier, thus confirming the return of Northern Transylvania to Romania.
Sandu Tudor
As noted by Neagu Rădulescu, "Credința" came to an abrupt "sad end", which Tudor took shame in recounting. An focused on his new passion, aviation, and bragged about having survived a plane crash. He maintained his religious focus during World War II. The Ion Antonescu dictatorship joined in Nazi Germany's attack on the Soviet Union. Romania's war on the Eastern Front gave an impetus to Romanian monastic life, by restoring the Romanian church's direct contacts with Russian Orthodoxy. The country witnessed the arrival of Russian monks, including one trained at the prestigious Optina Monastery. He was Ivan Kulygin (known to Romanians as "Ivan Kulîghin", "Ivan Kulâghin", or "Ivan Străinul", lit. "Ivan the Foreigner"), a victim of the Soviet regime, who took refuge to Romania after the Battle of Stalingrad.
