Union of the Soviet Socialist Republics (USSR) was born shortly after the victory of the Russian Revolution and the establishment of Bolshevik rule in Russia. The rulers of the USSR planned to establish a government which was based on socialist doctrines in order to lead the society toward communism. In this path, it was necessary to demolish all remaining structures from Tsarist Russia and replace them with new ideologically correct establishments. In this process, the first unavoidable step was changing the culture and mentality of the Russian people and the second step was eradication of poverty and removal of exploitation through which people would be convinced of the new ruling system. One of the main areas in the creation of the appropriate bases for the new ruling system was theatre. Infact, the new ruling system played more attention to playwrights than to other artists. The central committee of the Communist party believed that it was in the power of the playwrights to disseminate the new ideology along with the ideas of its new rulers among the public and persuade them of the socialist utopia.October Revolution in Russia and victory of Marxist-Leninist ideological Revolution and establishment of Soviet Union had a great influence on all aspects of individual and social lives of the people.One of these areas of influence was establishment of a powerful and strict governmental system in the field of theater and particularly in dramaturgy (dramatic literature and playwriting). The operation of such governmental system undermined play writing during that period, so that none of the plays written within that era, in contrast with previously written plays, did not find international importance, white playwriting in this period of time should be the inheritor of fruitful, distinguished works of playwrights such as Pushkin, Chekhov, Googol and others. In this era and under the influences of the established ruling system, dramaturgy was at service of describing, deepening and bestowing legit.imacy to the ruling ideology and its promotion and thus it began its degradation. In this paper, the author has tried to infer, extract and summarize the trends and objectives dominant in the theater of that era in the form of "orders". These orders were in fact ideological instruction of the new rulers for the dramaturgy of that period. Then the author has tried to recognize and introduce those indicators prescribed by the cultural-artistic policy makers of ex-Soviet union; the instructions which led to degradation and annihilation of dramaturgy at that time. It should be mentioned that the playwrights of that Socialist Union were bound to follow such instructions in their works. "Class struggle", "particular approaches of Socialist Realism", "development of a new positive character" were some of the prescribed characteristics of that period's dramaturgy.
