This period of Princess Marițica's life was curbed by an anti-conservative revolution. The opposition was initially peaceful, and issued a "Proclamation of Islaz", demanding more rights; it erupted into a more violent revolt on June 9, 1848, when officers Grigore Paleologu and Grigore Pereț shot at Prince Bibescu, who was taking a carriage ride outside Bucharest. They only managed to hit one of Bibescu's epaulettes. Various accounts suggest that Marițica was by her husband's side, though others have it that the Prince was traveling with his favorite minister, Alexandru Vilara. The following day, rebellious militiamen confronted the Prince with imperative requests for a liberal constitution. Though Gheorghe never made this pledge, he took another oath, "on my life and that of Her Highness the Princess", that "no Moskal shall enter this country".
