It was during his time in Paris that he met with Pierre-Joseph Proudhon, the anarchist philosopher who had come to advance a moderate small-scale property project (to counter both economic liberalism and socialism). Heliade used this opportunity to make the Romanian cause known to the staff of Proudhon's "La Voix de Peuple". Major French publications to which he contributed included "La Presse", "La Semaine", and "Le Siècle", where he also helped publicize political issues pertaining to his native land. Heliade was credited with having exercised influence over historian Élias Regnault; Nicolae Iorga argued that Regnault's discarded his own arguments in favor of a unified Romanian state to include Transylvania (a concept which Heliade had come to resent), as well amending his earlier account of the 1848 events, after being exposed to "Eliad's propaganda".
