THE POLITICAL TRIAL IS FREQUENTLY RESORTED TO BY REGIMES seeking to establish or reaffirm their legitimacy. Almost by definition the opposition is the target of such trials for it has questioned or challenged the incumbent regime's right to rule. The trial, when successfully engineered, reveals the opposition as not simply misguided, but as subversive, treasonous, and, in the case of the monarchies, sacrilegious. The condemnation of all or part of the opposition for sins towards God and country emphasizes the objective validity and immutability of the regime's tenets, the components of its charter myth.
Such trials have several functions, but three stand out among them. First, one may consider the propagandistic, mass communication function. The trial itself becomes the scene for the definition, re-affirmation, and manipulation of the regime's symbols and credos. Official doctrine is hammered home to the society as a whole, under highly dramatic circumstances inherent in the trial process. The unfolding of the drama often evokes far greater public interest and concern than the routine propaganda efforts of the controlled mass media.
