The present paper fouses on the relationship between ideology and the political discourse, as well as on the relationship between ideology and propaganda. Our aim is to undeline the discoursive prospective of the ideology, seen into the global frame of the general communication process. A special attention is given to van Dijk´s three-dimension model of the ideologic discourse, based on a interdisciplinary theory of ideology which takes into consideration the level of the ideology´s nature, the level of its cognitive rappresentation and the level of its modalities of expression.
