This paper aims to discover, develop and interpret the thematic, stylistic and dramatic elements of Fatima Gallaire’s plays which contribute to emerge the patriarchy’s dramatisation as an opportunity of theatrical and sociological approach of situations of harmonic or problematical relations between fathers and daughters, woman’s oppression and efforts of feminine emancipation in the Maghrebi or Mediterranean family and society. The plays which express in a theatrical, morphological and thematic point of view these parameters and which will form the corpus of our research are the following: ‘Princesses’, ‘Les Co-épouses’, ‘Rimm la gazelle’, ‘Au coeur la brûlure’, ‘Les Richesses de l’hiver’ and ‘Molly des Sables’. The followed methodology is based on the approach of the following optics of analysis: the fidelity in the representation of the sociocultural reality of the patriarchal family in Algeria, the polyvalence of her theatralization, the nature of distance, conflict or harmony which characterizes the bond between father and daughter and the catharsis’ propositions given by the playwright. The conclusions’ evaluation ambitions to proof how the approach of patriarchy’s theme in Fatima Gallaire’s theatre overtakes the simple registration of a concrete social and cultural reality, and becomes the opportunity to treat timeless and universal situation, such as the claim of the human rights and liberty, the respect of religious, ethnic and cultural differences, and the restoration of the female value and respect.
