contact with Soviet overseers. In 1925, the question of Romania's borders as posed by the Comintern led to protests by Cristescu and, eventually, to his exclusion from the party (see Balkan Communist Federation). Around the time of the party's Fifth Congress in 1931, the Muscovite wing became the PCdR's main political factor: Joseph Stalin replaced the entire party leadership, including the general secretary Vitali Holostenco—appointing instead Alexander Stefanski, who was at the time a member of the Communist Party of Poland. The interior wing began organizing itself as a more efficient conspiratorial network through regained Comintern control. The onset of the Great Depression in Romania, and the series of strikes infiltrated (and sometimes provoked) by the interior wing signified relative successes (see Lupeni Strike of 1929), but gains were not capitalized—as lack of ideological appeal and suspicion of Stalinist directives remained notable factors. In parallel, its leadership suffered changes that were meant to place it under an ethnic Romanian and working-class leadership—the emergence of a Stalin-backed group around Gheorghe Gheorghiu-Dej before and after the large-scale Grivița Strikes. In 1934, Stalin's Popular Front doctrine was not fully passed into the local party's politics, mainly due to the Soviet territorial policies (culminating in the 1939 Molotov–Ribbentrop Pact) and the widespread suspicion other left-wing forces maintained toward the Comintern. The Communists did, nevertheless, attempt to reach consensus with other groupings on several occasions (in 1934–1943, they established alliances with the Ploughmen's Front, the Hungarian People's Union, and the Socialist Peasants' Party), and small Communist groups became active in the leftist sections of mainstream parties. In 1934, Petre Constantinescu-Iași and other PCdR supporters created Amicii URSS, a pro-Soviet group reaching out to intellectuals, itself banned later in the same year. During the 1937 elections, the Communists backed Iuliu Maniu and the National Peasants' Party against King Carol II and the Gheorghe Tătărescu government (who had intensified repression of Communist groups), finding themselves placed in an unusual position after the Iron Guard, a fascist movement, signed an electoral pact with Maniu; participation in the move was explained by Communist historiography as provoked by the Social-Democrats' refusal to collaborate with the PCdR. In the years following the elections, the PCdR entered a phase of rapid decline, coinciding with the increasingly authoritarian tone of King Carol's regime (but in fact inaugurated by the 1936 Craiova Trial of Ana Pauker and other high-ranking Communists).
