Discourse analysis is rooted in the structure of a language and as a fundamental scale is of great significance. In the post-structuralism perspective, discourse analysis crosses the borders of language and goes into the essence of meaning. Scientific movement including structuralism, formalism, and modernism in literary analysis; semiotics, hermeneutics and post-structuralism in the form of language, meaning and text have come to help discourse analysis. By analyzing bigger chunks of statements and the have come to help discourse analysis. By analyzing bigger chunks of statements and the whys/hows of language use, linguistics has opened new spaces for discourse analysis. This has been carried out in two ways: discourse and the act of meaning making where Austin, Witgenestein, Saussaur, Barte, Derrida, Foucault, and Norman Fairclaugh, have played major roles. The discourse analysis viewpoint also emphasizes on meaning-making and freeing the text from a holistic, general and one-for-all meaning and the multiplicity of meanings hidden within the text has led to a variety of ideas regarding "meaning". In this field, Foucault, La kuoo, and Moufett are known as the most prominent figures. These historical efforts in half a century have led to the expansion of the concept of discourse and ways of discourse analysis. The theories of critical discourse analysis which has generally been shaped in the postmodern thought basis also have taken the text, author, reader and the context into account,.They have also reshaped and deconstructed the text and have created many new ideas in the realm of discourse analysis. In the present paper, it is intended to deconstruct the Command of Constitutionalism as an exceedingly significant historical document and locate the discourse gaps in them. The main subject of this paper is the critical analysis of the Command of Constitutionalism Text in the form of a discourse theory. The methodology has been taken from Norman Fairclaugh's style. The results show that there has been a new discourse gap :tromthe side of the modem discourses in the traditional discourse formed in the Ghajri Dynasty.
