When the Paris Peace Conference confirmed the creation of Greater Romania, Catholics of both churches represented 13 to 14% of its population. During the Conference, the Ion I. C. Brătianu cabinet and representatives of Pope Benedict XV established preliminary contacts, a gesture coinciding with the encyclical "Pacem, Dei Munus Pulcherrimum" (which, in turn, redefined relations between the Holy See and individual states). Negotiations were continued by the Alexandru Vaida-Voevod cabinet, who appointed the Greek-Catholic priest Vasile Lucaciu as its representative, and by that of Alexandru Averescu. Through a decision taken by Foreign Minister Duiliu Zamfirescu, the outgoing Ghika was replaced with Dimitrie Pennescu, who was Romania's first Ambassador to the Vatican ("see Holy See–Romania relations"). The Apostolic Nunciature in Romania was set up as a result of this. The first person to hold this office was Archbishop Francesco Marmaggi, who took charge in October 1920.
