Ion Antonescu in the context of "Gheorghe Gheorghiu-Dej"

The 1944 Romanian coup d'état, better known in Romanian historiography as the Act of 23 August (Romanian: Actul de la 23 august), was a coup d'état led by King Michael I of Romania during World War II on 23 August 1944. With the support of several political parties, the king removed the government of Ion Antonescu, which had aligned Romania with Nazi Germany, after the Axis front in northeastern Romania collapsed in the face of a successful Soviet offensive. The Romanian Army declared a unilateral ceasefire with the Soviet Red Army on the Moldavian front, an event viewed as decisive in the Allied advances against the Axis powers in the European theatre of World War II. The coup was supported by the Romanian Communist Party, the Social Democratic Party, the National Liberal Party, and the National Peasants' Party who had coalesced into the National Democratic Bloc in June 1944.

Para-fascism are authoritarian conservative movements and regimes that adopt characteristics associated with fascism such as personality cults, paramilitary organizations, symbols and rhetoric, while diverging from conventional fascist tenets such as palingenetic ultranationalism, modernism, and populism. Para-fascism often emerges in response to the need for a facade of popular support in an age of mass politics, without a genuine commitment to revolutionary nationalism, instead focusing on maintaining tradition, religion, and culture. Para-fascist regimes may co-opt or neutralize genuine fascist movements.

The historian Roger Griffin defines the following regimes and movements as para-fascist: Austrofascism in the Federal State of Austria led by Engelbert Dollfuss and Kurt Schuschnigg, Metaxism in the Greek '4th of August Regime', the "New State" of António de Oliveira Salazar's Portugal, the Bando nacional and the FET y de las JONS led by Francisco Franco in the Spanish State, Kingdom of Hungary led by Miklós Horthy, and the Révolution nationale in Vichy France led by Philippe Petain; the dictatorships of Carol II and Ion Antonescu in the Kingdom of Romania, Miguel Primo de Rivera's dictatorship in Spain and Antanas Smetona's Lithuanian Nationalist Union in Lithuania have also been referred to as para-fascist. While most historians of fascism agree that these regimes were not totally fascist, many authors do acknowledge that they have some kind of connection with fascism, either by being partially influenced by it or by co-opting some genuine fascist groups. The words used by different historians to characterize these conservative regimes include, apart from parafascism: semi-fascist, fascisant, fascistic, fascistized, quasi-fascist, and others.

The Romanian Communist Party (Romanian: Partidul Comunist Român [parˈtidul komuˈnist roˈmɨn]; PCR) was a communist party in Romania. Founded in 1921, the party assumed to the power of Romania in 1947 and became the founding and ruling party of the Socialist Republic of Romania, until its overthrow in the Romanian revolution in 1989. Ideologically committed to Marxism–Leninism, the party oversaw Romania's departure from the Soviet satellite status and incorporation of national communism.

The successor to the pro-Bolshevik wing of the Socialist Party of Romania, it gave an ideological endorsement to a communist revolution that would replace the social system of the Kingdom of Romania. After being outlawed in 1924, the PCR remained a minor and illegal grouping for much of the interwar period and submitted to direct Comintern control. During the 1920s and the 1930s, most of its activists were imprisoned or took refuge in the Soviet Union, which led to the creation of competing factions that sometimes came into open conflict. That did not prevent the party from participating in the political life of the country through various front organizations, most notably the Peasant Workers' Bloc. In 1934–1936, PCR reformed itself in the mainland of Romania properly, with foreign observers predicting a possible communist takeover in Romania. The party emerged as a powerful actor on the Romanian political scene in August 1944, when it became involved in the royal coup that toppled the pro-Nazi government of Ion Antonescu. With support from Soviet occupational forces, the PCR pressured King Michael I into abdicating, and it established the Romanian People's Republic in December 1947.

Gheorghe I. Tătărescu (also known as Guță Tătărescu, with a slightly antiquated pet form of his given name; 2 November 1886 – 28 March 1957) was a Romanian politician who served twice as Prime Minister of Romania (1934–1937; 1939–1940), three times as Minister of Foreign Affairs (interim in 1934 and 1938, appointed to the office in 1945-1947) and once as Minister of War (1934). Representing the "young liberals" faction inside the National Liberal Party (PNL), Tătărescu began his political career as a collaborator of Ion G. Duca, becoming noted for his anticommunism and, in time, for his conflicts with the PNL's leader Dinu Brătianu and the Foreign Minister Nicolae Titulescu. During his first time in office, he moved closer to King Carol II and led an ambivalent policy toward the fascist Iron Guard and ultimately becoming instrumental in establishing the authoritarian and corporatist regime around the National Renaissance Front. In 1940, he accepted the cession of Bessarabia and Northern Bukovina to the Soviet Union and had to resign.

After the start of World War II, Gheorghe Tătărescu initiated a move to rally political forces in opposition to Ion Antonescu's dictatorship, and sought an alliance with the Romanian Communist Party (PCR). He was twice expelled from the PNL, in 1938 and 1944, creating instead his own group, the National Liberal Party-Tătărescu, and representing it inside the communist-endorsed Petru Groza cabinet. In 1946-1947, he was also the President of the Romanian Delegation to the Peace Conference in Paris. Then, relations between Tătărescu and the PCR began to sour, and he was replaced from the leadership of both his own party and the Foreign Ministry when his name was implicated in the Tămădău Affair. Following the Communist takeover, he was arrested and held as a political prisoner while being called to testify in the trial of Lucrețiu Pătrășcanu. He died soon after his release from prison.

The Iași pogrom (Romanian pronunciation: [ˈjaʃʲ] , sometimes anglicized as Jassy) was a series of pogroms launched by governmental forces under Marshal and Leader Ion Antonescu in the Romanian city of Iași against its Jewish community, which lasted from 28 June to 30 June 1941. According to Romanian authorities, over 13,266 people, or one third of the Jewish population, were massacred in the pogrom itself or in its aftermath, and many were deported. It was one of the worst pogroms during World War II.
