Despite much research about pure-writing, no satisfying one about its history and theories has been conducted to date. The present paper aims to study the historical background of this writing method and its theoretical bases up to the constitutional era.  This study shows that, contrary to what it seems, pure-writing is not a new method and its history dates back to the fifth century AH. Referring to remains of past periods, the article emphasizes that this kind of writing got increasing attention since the second half of the thirteenth century AH, under the influence of widespread Dasatiri terms especially the nationalism movement. This paper addresses the following questions: 1- Was pure-writing based on any particular theory of Shu'ubiyya in the previous periods? 2- Was there any relationship between pure-writing and nationalism? 3- If there were such a relationship, did all nationalist movements propagate pure-writing or just a some particular ones insisted on it?
