 From that point on, opposition to Ghica's rule took the form of Freemason and "carbonari"-inspired conspiracies, formed around young politicians such as Mitică Filipescu, Nicolae Bălcescu, Eftimie Murgu, Ion Ghica, Christian Tell, Dimitrie Macedonski, and Cezar Bolliac (all of whom held Câmpineanu's ideology in esteem)—in 1840, Filipescu and most of his group (who had tried in vain to profit from the Ottoman crisis engendered by Muhammad Ali's rebellion) were placed under arrest and imprisoned in various locations.Noted abuses against the rule of law and the consequent threat of rebellion made the Ottoman Empire and Russia withdraw their support for Ghica in 1842, and his successor, Gheorghe Bibescu, reigned as the first and only prince to have been elected by any one of the two Assemblies.In Moldavia, the situation was less tense, as Sturdza was able to calm down and manipulate opposition to Russian rule while introducing further reforms.
