Front of National Unity

Front of National Unity or National Unity Front (, FJN) was a popular front supervising elections in the Polish People's Republic which also acted as a coalition for the dominant communist Polish United Workers' Party (PZPR) and its allies. It was founded in 1952 as National Front (Front Narodowy) and renamed to Front of National Unity in 1956. It was the heir of the Democratic Bloc (Blok Demokratyczny) which ran in the elections of 1947 before the merger between communists and socialists.

The Front was created by and was subordinate to the PZPR. During elections it had a near monopoly (varied depending on particular time) on registering candidates who had the right to participate in the elections. As was the case with other popular fronts in the Soviet bloc, the member parties of the Front were largely subservient to the PZPR; they had to accept the PZPR's "leading role" as a condition of their existence.

On 16 July 1983 at a meeting in Warsaw of the presidium of the National Committee of the Front of National Unity, the dissolution of that organization was announced and an appeal was made for FJN members to join Patriotic Movement for National Rebirth (Patriotyczny Ruch Odrodzenia Narodowego, PRON).
