The National Democratic Front received recognition in the December 1944 government of General Nicolae Radescu and, although given a number of important posts, was generally held to a role subordinate to that of the National Peasant, the Liberal, and the Social Democratic parties. In late January 1945 after a visit to Moscow by Pauker and Gheorghiu-Dej, the leftist leadership within the government initiated a virulent campaign of disorder, agitation, and denunciation against Radescu and called for the replacement of his regime with one to be formed by the National Democratic Front. The anti-Radescu campaign was prolonged and intensified by the Communists who, through their control of the printer's union, were able to silence the opposition press and thus enhance their own propaganda. In February 1945, during a staged demonstration, the Communists provoked an incident in which several participants were killed. Demands were made for Radescu's arrest, and he was forced to seek asylum within a foreign mission. Using this latest incident as a pretext, Soviet Deputy Commissar for Foreign Affairs Andrei Vyshinsky, who arrived from Moscow within two days of the event, forced King Michael to accept a National Democratic Front government to be headed by Petru Groza, the leader of the Plowman's Front and longtime communist sympathizer. The government installed by Groza on March 6, 1945, was dominated by Communists and fellow travelers and represented an effective seizure of power by relatively peaceful means. Although a few dissident former members of the Liberal and National Peasant parties were given posts to maintain the facade of representative government, no leaders or representative members of the historic political parties were included. After recognition by the Soviet Union in August 1945 and by the United States and Great Britain in February 1946, the Groza government held rigged elections for the Grand National Assembly and emerged with 379 of the 414 seats. Having thus achieved legislative as well as executive control, the Communists proceeded methodically during the following year to eliminate all political opposition. National Peasant and Liberal leaders were arrested and tried, and these two major parties were outlawed in June 1947. This action was followed in the spring of 1948 by the fusion of the Social Democrats with the Communists into a new party called the Romanian Workers' Party, which the Communists controlled. As a final step the National Democratic Front was reorganized into the People's Democratic Front, which then included the Romanian Workers' Party, the Plowman's Front, and two new puppet organizations--the National Popular Party and the Hungarian People's Union.
