The “Le Pen phenomenon” designates the sum constituted by the elaboration of a politicalbrand located at the far-right and by the conflictual reactions that it provokes within theFrench society. The objectivization of this phenomenon lies in the analysis of the FrontNational ideology as it is this of a political brand which must produce an original doctrinalcontent in order to distinguish it from the others parties but also in the study of the socialmovement – or the movement of the social – which it is the cause of. The category of thesacred comes to shed the discursive sets which are discernible just as well in the FrontNational words as those of its political and associative opponents. The research is going onwith the analysis of the French far-right main ideological schemas, which is based on ahistory of ideas which starts with the counter-revolutionary thought. The Durandianmethodology of the semantic basin allows to identify the cardinal stages of the far-rightnationalism ideological formation. The examination of this ideology comes to an end with theanalysis of the Front National contemporary discourse and the mythanalytic comparison ofthe Jean-Marie Le Pen and Marine Le Pen candidacies at the time of 2007 and 2012 Frenchpresidential elections.
