After the death of the Queen Mother Marie in 1938 and the deposition of Carol II in 1940, Elisabeth played the role of First Lady of Romania. Ambitiously, the princess had indeed no remorse to follow her brother's policy, even when she showed herself tyrannical with other members of the royal family. After the return to the throne of Michael I and the establishment of the dictatorship of Marshal Ion Antonescu, Elisabeth stayed out of politics. However, from 1944, she forged links with the Romanian Communist Party and openly conspired against her nephew, who now considered her a spy. In early 1947, she received in her domain of Banloc the Marshal Tito, who deposed another of her nephews, the young King Peter II of Yugoslavia. Finally, through Alexandru Scanavi, the Princess participated in the financing of the guerrilla who fought against her former brother-in-law, the now King Paul I, in Greece.
