After 1846, the regime tried to reconcile with young liberals, and Vulpache emerged as a mediator between the two sides. Nevertheless, tensions between the conservatives and the liberals brought down the regime: a Wallachian Revolution erupted in mid 1848, and Bibescu was forced to abdicate and leave into exile. Vulpache also fled the country, returning after pacification with the Imperial Russian Army, which controlled part of Bucharest, and serving for a while as Minister of the Interior. His father stayed behind in Bucharest. As the revolutionary government fell and Cantacuzino, as "Caimacam", inaugurated a conservative regime, he was reappointed to the school board alongside Poenaru, Băleanu, and, from 1851, Apostol Arsache and Ion Emanuel Florescu. While there, he ordered budget cuts, sacking teachers who had participated in the Revolution and were unrepentant. His son, as Secretary of State, carried out the order, and, as records of the time suggest, the number of active schools dropped rapidly. Meanwhile, Vulpea was also given a position on a committee which evaluated the agrarian issue. Composed of conservatives, it outlined the standard alternative to land reform, suggesting a gradual termination of socage and corvée through boyar–peasant contracts.
