In the paper, the origin of methods of totalitarian pressure on academic milieu, formed in time of Poland's occupation is presented. The comparison between repression of occupational authorities and scholar's attitudes and mentality is shown. In these circumstances, the idealisation od academic science appeared on one hand and existential fight, forcing coping with conditions under occupation on the other. The after-war policies of communist regime were implemented in two stages: of 'mild revolution' and 'ideological offensive'. Both these stages forced specific methods of academic milieu enslavement, first of all of 'opening the science' and gradual destruction of connections inside the milieu. The instruments of science policy proved to be useful for the regime: personnel and financial policy and legislation. Propaganda activities were most visible, but it was the pressure through bureaucratic institutions that proved to be much more efficient. The main part of the paper consists of presentation of methods of enslavement of academic milieu used by authorities of the party and the state and of scholar's reactions, including splendid isolation and policy of 'saving the substance'
