Bolshevik-inspired maximalist faction won control of Romania's Social-Democratic party—the Socialist Party of Romania, successor to the defunct Romanian Social-Democratic Workers' Party and the short-lived Social Democratic Party of Romania (the latter was refounded in 1927, reuniting those opposed to communist policies). The establishment was linked with the socialist group's affiliation to the Comintern (just before the latter's Third Congress): after a delegation was sent to Bolshevist Russia, a group of moderates (including Ioan Flueraș, Iosif Jumanca, Leon Ghelerter, and Constantin Popovici) left at different intervals beginning with January 1921. The party renamed itself the Socialist-Communist Party () and, soon after, the Communist Party of Romania ( or PCdR). Government crackdown and competition with other socialist groups brought a drastic reduction in its membership—from the ca. 40,000 members the Socialist Party had, the new group was left with as much as 2,000 or as little as 500; after the fall of one-party rule in 1989, Romanian historians generally asserted that the party only had around 1,000 members at the end of World War II. Other researchers argue that this figure may have been intentionally based on the Muscovite faction figures and, as such, underestimated to undermine the influence of the internal faction; this estimate was afterwards promoted in post-communist historiography to reinforce a stereotypical image of the regime as illegitimate. The early Communist Party had little influence in Romania. This was due to a number of factors: the country's lack of industrial development, which resulted in a relatively small working class (with industry and mining employing fewer than 10% of the active population) and a large peasant population; the minor impact of Marxism among Romanian intellectuals; the success of state repression in driving the party underground and limiting its activities; and finally, the party's "anti-national" policy, as it began to be stated in the 1920s—supervised by the Comintern, this policy called for the breakup of Greater Romania, which was regarded as a colonial entity "illegally occupying" Transylvania, Dobruja, Bessarabia and Bukovina (regions that, the communists argued, had been denied the right of self-determination). In 1924, the Comintern provoked Romanian authorities by encouraging the Tatarbunary Uprising in southern Bessarabia, in an attempt to create a Moldavian republic on Romanian territory; also in that year, a Moldavian Autonomous Soviet Socialist Republic, roughly corresponding to Transnistria, was established inside the Soviet Union. At the same time, the left-wing political spectrum was dominated by Poporanism,
