he was obstructing revolution and aiming to take control of the Iron Guard, and that he had been transformed into a tool of Freemasonry (see Anti-Masonry). The political conflict coincided with major social challenges, including the influx of refugees from areas lost earlier in the year and a large-scale earthquake affecting Bucharest. Disorder peaked in the last days of November 1940, when, after uncovering the circumstances of Codreanu's death, the fascist movement ordered retaliations against political figures previously associated with Carol, carrying out the Jilava Massacre, the assassinations of Nicolae Iorga and Virgil Madgearu, and several other acts of violence. As retaliation for this insubordination, Antonescu ordered the Army to resume control of the streets, unsuccessfully pressured Sima to have the assassins detained, ousted the Iron Guardist prefect of Bucharest Police Ștefan Zăvoianu, and ordered Legionary ministers to swear an oath to the Conducător. His condemnation of the killings was nevertheless limited and discreet, and, the same month, he joined Sima at a burial ceremony for Codreanu's newly discovered remains. The widening gap between the dictator and Sima's party resonated in Berlin. When, in December, Legionary Foreign Minister Mihail R. Sturdza obtained the replacement of Fabricius with Manfred Freiherr von Killinger, perceived as more sympathetic to the Iron Guard, Antonescu promptly took over leadership of the ministry, with the compliant diplomat Constantin Greceanu as his right hand. In Germany, such leaders of the Nazi Party as Heinrich Himmler, Baldur von Schirach and Joseph Goebbels threw their support behind the Legionaries, whereas Foreign Minister Joachim von Ribbentrop and the Wehrmacht stood by Antonescu. The latter group was concerned that any internal conflict would threaten Romania's oil industry, vital to the German war effort. The German leadership was by then secretly organizing Operation Barbarossa, the attack on the Soviet Union. Legionary Rebellion and Operation Barbarossa Antonescu's plan to act against his coalition partners in the event of further disorder hinged on Hitler's approval, a vague signal of which had been given during ceremonies confirming Romania's adherence to the Tripartite Pact. A decisive turn occurred when Hitler invited Antonescu and Sima both over for discussions: whereas Antonescu agreed, Sima stayed behind in Romania, probably plotting a coup d'état. While Hitler did not produce a clear endorsement for clamping down on Sima's party, he made remarks interpreted by their recipient as oblique blessings. On 14 January 1941 during a German-Romanian summit, Hitler informed Antonescu
