During the Eastern Front offensive of 1944, the Soviet Army occupied the northwestern part of Moldavia as a result of armed combat that took place between the months of April and August of that year, while Romania was still an ally of Nazi Germany.
The rest of the territory was occupied after Romania changed sides in World War II, as a result of the royal coup launched by King Michael I on August 23, 1944.
The armistice convention and eventually the Paris Peace Treaties of 1947 provided a legal basis for the Soviet military presence in Romania, which lasted until 1958, reaching a peak of some 615,000 personnel in 1946.
Romanian troops entered World War II in June 1941 as part of Operation Barbarossa, under the German High Command.
By the end of 1943, the Red Army had regained control over most of the Soviet territory, and was advancing westward beyond the borders of USSR to defeat Nazi Germany and its allies.
On August 23, 1944, King Michael, supported by all major parties, launched a coup d'état, thereby overthrowing the pro-Nazi government of Ion Antonescu, and putting Romania's Army on the side of the Allies.
"[14] Historians Mădălin Hodor [ro] and Vadim Guzun disputed these assertions, the latter noting that "the USSR occupied, dismembered and Sovietized Romania.
"[15] Article 3 of the Armistice Agreement with Romania[16] (signed in Moscow on September 12, 1944), stipulated that The Government and High Command of Rumania will ensure to the Soviet and other Allied forces facilities for free movement on Rumanian territory in any direction if required by the military situation, the Rumanian Government and High Command of Rumania giving such movement every possible assistance with their own means of communications and at their own expense on land, on water and in the air.Article 11 of the same agreement stipulated that Romania will compensate the Soviet Union for losses suffered in the war "to the amount of three hundred million United States dollars payable over six years in commodities (oil products, grain, timber products, seagoing and river craft, sundry machinery, et cetera)."
In line with Article 14 of the Armistice Agreement, two People's Tribunals were set up for the purpose of trying suspected war criminals, one in Bucharest, and the other in Cluj.
[18] On November 8, 1945, King Michael's name day, an anti-communist demonstration in front of the Royal Palace in Bucharest was met with force, resulting in dozens of casualties.

[32] The General Directorate of the Security of the People (Romanian initials: DGSP, but more commonly just called the Securitate) was officially founded on August 30, 1948, by Decree 221/30.
The Securitate was set up by SMERSH, an NKVD unit charged with dismantling the existing intelligence agencies and replacing them with Soviet-style bodies in the Soviet-occupied countries of Eastern Europe.
In October 1944, the Sănătescu government, at the request of the Allied Control Commission, began arresting young Romanian citizens of German descent, who were eventually placed at the disposal of the Soviet command.
At the request of the Allied Commission, the Rădescu government ordered the forced transportation by train of Transylvanian Saxons to the Soviet Union.
Generally, they were a contributing factor to the draining of Romania's resources, in addition to the war reparations demanded by the Armistice Agreement and the Paris Peace Treaties, which had been initially set at 300 million U.S.
[35] The Soviet contribution to the creation of the SovRoms consisted mostly in reselling leftover German equipment to Romania, at systematically overvalued prices.
One of these companies was Sovromcuarț, which started its operations in 1950 at the Băița mine in Bihor County, under a name that was meant to conceal the true object of its activity.
[38] Its initial workforce consisted of 15,000 political prisoners; after most of them died of radiation poisoning, they were replaced by local villagers, who were completely unaware of the fact that they were working with radioactive material.
[43] All ore was shipped abroad for processing, initially to Sillamäe in the Estonian SSR; the uranium concentrate was then used exclusively by the Soviet Union.
