On 20 January 1941, the Iron Guard attempted a coup, combined with a pogrom against the Jews of Bucharest. On 22 January, at the height of the Rebellion, the Iron Guard carried out the ritual murder of 200 Jews at the Bucharest slaughterhouse, while the Guardists were singing Christian hymns, "an act of ferocity perhaps unique in the history of the Holocaust". Within four days, Antonescu had successfully suppressed the coup. The Iron Guard was forced out of the government. Sima and many other legionnaires took refuge in Germany, while others were imprisoned. Antonescu abolished the National Legionary State, in its stead declaring Romania a "National and Social State."
