Antonescu, who had the support of Romania's military, met with Adolf Hitler on 14 January 1941, in Germany. During this meeting he promised Hitler the cooperation of Romania in any future German conflict with the Soviet Union, and gained Hitler's silent agreement to eliminate Antonescu's opponents in the Legionnaire Movement. Between 17 and 19 January the Legionnaire movement conducted a series of "lectures" throughout Romania, designed to demonstrate the national socialist nature of their movement and to show their loyalty to Hitler.
