Regulamentul Princes. He created an especially vibrant unionist cell and electoral committee, which also comprised figures such as Barbu Bălcescu, Gheorghe Chițu, and Grigore Lăceanu; together, they put out a nationalist paper, Vocea Oltului. They ended up rejecting Bibescu, whom they found to be "timid". In May, Konstantin Basily arrived in Bucharest to observe the situation on Russia's behalf. He was welcomed by the Bibescu party, whose members complained that Costaforu was inciting an anti-boyar revolution in the provinces. Basily was upset, and demanded that Costaforu tone down his party's propaganda; Costaforu diverted attention from his own radicalism by informing him that Bibescu had preemptively endorsed secularization. Basily became disappointed by both camps, promising them that Russia would never allow for monastery land to be confiscated. Știrbei, meanwhile, also published a constitutional project with virtually the same proposals as Crețulescu's. The Caimacam party also reemerged, once Bosianu again withdrew from the National Party venture, establishing his own Unionist Committee, and hoping to elect Dimitrie Ghica as Prince. Very few joined him, since, at the time, the Beizadea himself supported the notion of electing a foreigner. Bosianu established his own newspaper, called România. It depicted itself as a moderate and dispassionate voice in politics, and on such grounds presented arguments in support of the common unionist platform; by June, Bosianu himself had endorsed the project to import a Western European ruling house.

In July 1857, the debuting painter Theodor Aman of Craiova completed an allegorical canvass, the Union of the Principalities. Hailed as a milestone in patriotic artistry, it was followed soon after by mass prints of Petre Alexandrescu's similarly titled piece. Aricescu and Rucăreanu's work in theater was taken up in Bucharest by brothers Costache and Iorgu Caragiale. Their vaudevilles ridiculed an emerging mass panic, according to which a comet would strike Wallachia before the union could take place. The democratic side of unionism was by then completely free to organize, and its most radical proponents, C. A. Rosetti and Christian Tell, regained Bucharest during June. Highly popular with what Bălăceanu called the "socialist youth", they
