While liberating Serbia from fascism in the autumn of 1944 and in early 1945, under
the pretence of punishing ‘the enemies of the state and collaborationists’, the new partisan
government also punished their political and class enemies. These processes ranging from
arrests and interrogations to mass executions on secret locations, were run by the Department
of National Security, also known as OZNA. During these processes, usually without trials, OZNA
secretly executed between 55 and 60 thousand citizens of Serbia.
