In post-war (WW2) Poland, power was actually in the hands of the elite of the Polish Workers’ Party (PPR). An especial role was play by the central party apparatus, whose task was to implement the decisions of the narrow party leadership. The executive cadre of the apparatus was the members of the PPR Central Committee Secretariat, managers and deputy managers of Central Committee departments, directors of the party schools, and the leadership of the Central Party Control Commission. The executive cadre of the PPR’s central apparatus was fairly diversified in terms of social and ethnic descent, and education. The predominant members were activists who spent the World-War 2 years in the Soviet Union. The characteristic shared by 85% members of the top executive cadre was their long service in the communist movement. They came from one ideological generation of party activists and formed a tightly-knit group of professional revolutionaries. In 1944 - 1948 they were comparatively young, which enabled most of them to survive in the party elite until the late nineteen sixties.
