Soviet occupation of Romania The Soviet occupation of Romania refers to the period from 1944 to August 1958 , during which the Soviet Union maintained a significant military presence in Romania . The fate of the eastern territories of Romania occupied by the Red Army and eventually incorporated into the Soviet Union is treated separately in the article on Soviet occupation of Bessarabia and Northern Bukovina . During the Eastern Front offensive of 1944 , the Soviet Army occupied Romania . The northwestern part of Moldavia was occupied as a result of armed combat that took place between the months of May 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 on August 23 , 1944 . On that date , the King announced that Romania had unilaterally ceased all military actions against the Allied forces , accepted the Allied armistice offer , and joined the war against the Axis Powers . As no formal armistice offer had been extended yet , the Red Army occupied most of Romania as enemy territory prior to the signing of the Moscow Armistice of September 12 , 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 in 1946 . Soviet authors and the 1952 Constitution of Romania referred to the events of 1944 as the " liberation of Romania by the glorious Soviet Army " . On the other hand , most Romanian and Western sources use the term " Soviet occupation of Romania , " some applying it to the whole period from 1944 to 1958 . Background and beginning of the occupation . " See also : Romania during World War II and King Michael Coup " After having withdrawn its troops from Bessarabia and Northern Bukovina in response to the June 1940 Soviet Ultimatum , Romania entered an alliance with Nazi Germany and declared war on the Soviet Union . Romania n troops entered World War II in 1941 as part of Operation Barbarossa , under the German High Command . Following the recapturing of the territory annexed by the Soviet Union in 1940 , Romanian troops occupied Southern Ukraine all the way to the Southern Bug . However , Romania ' s eastern campaign ended in disaster , notably at Stalingrad . 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 . It was in this context that the Soviet forces crossed into Romania and occupied Northern and Eastern Moldavia . On August 23 , 1944 King Michael 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 . As a result , King Michael was spared the fate of another former German ally , Prince Kyril , Regent of Bulgaria , who was executed by the Soviets in 1945 . As a matter of fact , King Michael was the last monarch behind the Iron Curtain to lose his throne , on December 30 , 1947 . The coup facilitated the advance of the Red Army into Romania at an accelerated pace , and enabled the Romanian Army to liberate the country from the German occupation . In the absence of an actual signed armistice , the Soviet troops continued to treat the Romanians as a hostile force . The armistice was signed three weeks later , on September 12 , 1944 , " on terms Moscow virtually dictated . " The coup effectively amounted to a " capitulation " , an " unconditional " " surrender " to the Soviets and the rest of the Allies . In the wake of the cease fire order given by King Michael , between 114 , 000 and 160 , 000 Romanian soldiers were taken prisoners of war by the Soviets without resisting , and they were forced to march to remote detention camps , located in the Soviet Union ; about a third of the prisoners perished on the way . By September 12 , the Red Army had already gained control over much of the Romanian territory . Under the terms of its Armistice Agreement with the Allies , Romania became subject to an Allied Control Commission , composed of representatives of the Soviet Union , the United States , and the United Kingdom , while the Soviet military command exercised predominant , de facto authority . Bessarabia and Northern Bukovina were again incorporated into the Soviet Union . Founding documents . The Armistice Agreement . Article 3 of the Armistice Agreement with Romania ( signed in Moscow on September 12 , 1944 ) , stipulated that Article 18 of the same agreement stipulated that 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 . The plenipotentiary signatories to the armistice as indicated therein were : Paris Peace Treaties , 1947 . The effect of the Armistice Agreement ceased on September 15 , 1947 , when the Paris Peace Treaty with Romania entered into force . Article 21 , paragraph 1 of the new treaty provided the legal foundation for continued and unlimited Soviet military presence in Romania : The Romanian delegation at the Paris Conference was headed by Minister of Foreign Affairs Gheorghe Tătărescu . The Peace Treaty with Romania was signed on February 10 , 1947 , in the Salon de l ' Horloge of the Ministère des Affaires Étrangères . On the Romanian side , the four signatories were Gheorghe Tătărescu , Lucreţiu Pătrăşcanu , Ştefan Voitec , and Dumitru Dămăceanu . The signatories for the Allied powers included United States Secretary of State James F . Byrnes , Soviet Foreign Minister Vyacheslav Molotov , and British Secretary of State for Foreign and Commonwealth Affairs Ernest Bevin . Soviet forces in Romania , 1944 – 1956 . After the conclusion of the Armistice Agreement in 1944 , Soviet troops occupied the entire territory of Romania . Estimates of troop levels vary between 750 , 000 and 1 million ( estimates of British military officials ) , to between 1 and 1 . 5 million ( estimates of the Romanian General Staff ) ; many Western diplomats and experts refer to more than 1 million Soviet troops . 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 . Soviet officers restrained Romanian soldiers and police from firing on civilians , and Soviet troops restored order . The estimated strength of Soviet forces stationed in Romania ( including air , navy , ground , and security troops ) , from VE Day to 1952 , is shown in the table on the right . During the second half of 1946 , more than half of the combat capabilities of the Soviet Air Forces were residing outside the USSR , with the largest portion in Poland and Romania ( 2 , 500 planes in each country ) . The troop levels surged to a high of 615 , 000 in March 1946 , but they were drawn down after the conclusion of the Peace Treaty in 1947 . By the end of 1946 , Soviet units in Romania were concentrated in five areas : Craiova – Slatina , Sibiu – Alba - Iulia , Constanţa , and Brăila – Focşani . Troop levels reach a relatively stable level from May 1948 until October 1956 : two full divisions , plus supporting units adding up to roughly a third division . Although with the signing of the Austrian State Treaty in 1955 the reason for the presence of Soviet troops as stated in the Paris Peace Treaties ceased to exist , Premier Gheorghiu - Dej announced that these troops would stay as long as foreign soldiers continue to be stationed in West Germany . Soviet troops stationed in Romania participated in the suppression of the Hungarian Revolution of November 1956 . Soviet troop facilities inside Romania were off limits to all Romanians at the time . Reorganization of the Romanian Army . The Soviet occupation of Romania led to a complete reorganization of the Romanian Army under the supervision of Soviet Army representatives . The manpower of the Romanian army was limited by the Paris peace treaty to a total of 138 , 000 ( officers and troops ) ; however , under the Soviet occupation it grew far beyond the limits imposed by the treaty , through increasing militarization of Romania ' s population . By 1953 , regular army forces had grown to approximately 300 , 000 ; reserve army forces to approximately 135 , 000 ; and " interior " forces ( border guards , security brigades , et al . ) under the jurisdiction of the Ministry of the Interior to over 325 , 000 . At the inception of this organizational overhaul , pro - German elements were purged from the Romanian armed forces . In 1944 – 45 , two divisions composed of Romanian volunteers — former prisoners of war , trained and indoctrinated in the Soviet Union during the war , and also Communist activists such as Valter Roman — were formed : the Tudor Vladimirescu Division , under the command of Colonel Nicolae Cambrea , and the Horia , Cloşca şi Crişan Division , under the command of General Mihail Lascăr ( who was to serve as Minister of Defense from 1946 to 1947 ) . These two units were to form the nucleus of the new Romanian Army under Soviet control . Once the Romanian Communist Party took the reigns of power , 30 % of officers and noncommissioned officers ( mostly experienced soldiers , but at the same time a potential source of opposition to the Sovietization of the Army ) were purged from the military . Following the Romanian Workers ' Party seizure of political power , the Sovietization of the Romanian army went into full gear , under the supervision of the new Minister of Defense , Emil Bodnăraş . This reorganization involved the adoption of the Soviet model of military and political organization , and a change of the military doctrine of combat and defense , in the context of Romania ' s integration into the Soviet strategic system , at the dawn of the Cold War . Soviet officers were appointed as advisers charged with supervising the thorough reorganization of the army . They held leadership and surveillance positions in the main institutions of the state , but also in areas of lesser importance . In the beginning , they only held a few positions in the Ministry of Defense , the General Staff , and the political sections inside the army . With the passage of time , the number of Soviet advisers gradually increased , while at the same time their positions became permanent . In November 1952 , there were 105 permanent and 17 temporary Soviet adviser positions in military schools . After 1955 , their number began to decrease : 72 in 1955 , 63 in 1956 , 25 in 1957 and 10 in 1958 . After 1945 , new military regulations were developed , following the templates of the Red Army , and they were finalized in 1949 – 1952 . Consequently , a number of officers and military students were sent to the Soviet Union to complete their training . Between 1949 and 1952 , 717 Romanian students were being trained in the USSR , while in 1958 471 Romanian military students were pursuing education in the USSR . Their number decreased in the following years . Reorganization of the security services . Immediately following the August 23 , 1944 events , communists began to infiltrate the Ministry of Internal Affairs on a large scale . 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 . The SMERSH unit in Romania , called Brigada Mobilă , was led until 1948 by the NKVD colonel Boris Grünberg , also known in Romania as Alexandru Nicolschi . Its stated purpose was to " defend democratic conquests and guarantee the safety of the Romanian Peoples ' Republic against both internal and external enemies . " The first Director of the Securitate was NKVD general Panteleimon Bondarenko , who also went by the name Gheorghe Pintilie . Alexandru Nicolschi ( by then a general ) and another Soviet officer , Major General Vladimir Mazuru ( born Mazurov ) , held the two deputy director positions . Expulsion of Germans . The Red Army played a crucial role in the expulsion of Transylvanian Saxons from Romania that was initiated in January 1945 . 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 . Faced with ultimatums from the Soviet command , the Rădescu government ordered the forced transportation by train of Transylvanian Saxons to the Soviet Union . In a Protest ( dated January 13 , 1945 ) , the Rădescu government affirmed the Romanian government ' s duty to protect each of its citizens , regardless of ethnic origin , and noted the absence of a legal basis for the deportation of the Transylvanian Saxons . Such deportations would be outlawed in 1949 by the Fourth Geneva Convention ; its Article 49 states : " Individual or mass forcible transfers , as well as deportations of protected persons from occupied territory to the territory of the Occupying Power or to that of any other country , occupied or not , are prohibited , regardless of their motive . " SovRoms . The " SovRoms " were Soviet - Romanian joint ventures established on Romanian territory at the end of World War II , and lasting until 1954 – 1956 . An agreement between the two countries regarding the establishment of these enterprises was signed in Moscow on May 8 , 1945 . In theory , the purpose of these ventures was to generate funding for post - war reconstruction efforts . However , their real purpose was to provide resources for the Soviet side . Generally , they were a contributing factor to the draining of Romania ' s resources , in addition to the war reparation s demanded by the Armistice Agreement and the Paris Peace Treaties , which had been set at 300 million US $ . The Soviet contribution to the creation of the SovRoms consisted mostly in reselling leftover German equipment to Romania , at systematically overvalued prices . The total value of goods sent from Romania to the Soviet Union was estimated at 2 billion dollars , exceeding by far the amount of war reparations demanded by the Soviets . By 1952 , 85 % of Romanian exports were directed towards the Soviet Union . The last Sovrom was dissolved in 1956 . One of these companies was " Sovromcuarţ " , which started its operations in 1950 at the Băiţa mine in Bihor County , under a name that was meant to conceal the true object of its activity . 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 . Romania secretly delivered 17 , 288 tons of uranium ore to the Soviet Union between 1952 and 1960 , which was used , at least in part , in the Soviet atomic bomb project . Uranium mining continued there until 1961 . All ore was shipped abroad for processing , initially to Sillamäe in Estonia ; the uranium concentrate was then used exclusively by the Soviet Union . Comparison with Soviet occupation of other Eastern Bloc countries . Comparing the Soviet occupation of Romania to that of Bulgaria , David Stone notes : " Unlike Bulgaria , Romania had few cultural and historical ties with Russia , and had actually waged war on the Soviet Union . As a result , Soviet occupation weighted heavier on the Romanian people , and the troops themselves were less disciplined . "
