 In 1935, the organisation aligned itself with the outlawed Romanian Communist Party (PCR), an agreement inspired by the Stalinist "Popular Front" doctrine and signed in Ţebea (after negotiations overseen by Scarlat Callimachi).During this period, the Ploughmen's Front never obtained more than 0.30% of the vote.Outlawed together with all parties in 1938, through a law passed by the authoritarian regime of King Carol II, it remained active in clandestinity during the dictatorial rule of Ion Antonescu (when Groza was detained in 1943–1944), and surfaced after its fall in 1944 and the start of Soviet ascendancy and influence ("see Romania during World War II").
