[1] A worker who joined the Romanian Communist Party (PCR; later PMR) when it was banned, he was tried by the authorities of the Kingdom of Romania at Craiova alongside Ana Pauker and spent time in prison at Jilava, Doftana, and Caransebeș.
[3] When Gheorghiu-Dej began, by 1950, to move to consolidate his undisputed leadership of the party, he named the trusted Moghioroș to stand guard over and watch for chauvinism in the activities of Vasile Luca, another high-ranking ethnic Hungarian targeted for purging.
A year earlier, at a politburo discussion, he was the only member who did not grant even token acknowledgment to the idea that collectivization should happen gradually or cautiously, condemning the "opportunist-conciliatory line" as "non-Leninist, because we can't build socialism without collective farms".
Once in charge, he sharply criticized Pauker's more lenient approach, holding nightly meetings with officials to decide on new collective farms and ordering a scaled-down plan for the spring be accelerated during the summer of 1950.
[2] His wife Stela (born Esther Radoșovețkaia) was also a longtime party activist and represented the PMR on the editorial board of the Cominform journal For a Lasting Peace, for Popular Democracy.
