The Politburo was the highest political organ of the Central Committee of the Polish United Workers' Party, which existed from 1948 to 1990. The Politburo typically had between 9 and 15 members at any one time. Usually, several alternates (or candidates) were also elected to the Politburo, but unlike members, alternates did not possess voting rights.
The predecessor of the PUWP was the Polish Workers' Party (Polska Partia Robotnicza). In 1948, it merged with the Polish Socialist Party to form the PUWP. A chronological list of Politburo membership is provided below.
