Boris Godunov was completed by A.Puschkin just before Decembrist Revolt In 1825. Puschkin refused the three unity of the classical tragedy or romantic tragedy. Therefore we cant find not only unity of time and place, but also unity of action in Boris Godunov. Puschkin would create entirely new tragedy. In the process of writing the tragedy the great Russian poet thought of the free imagination and poetic of W.Shakespeare. Puschkin called Shakespeare my father. He would create the original Russian tragedy according to Russian conventions and history by overcoming the french classicism. Contemporary critics and writers didn’t accept Boris Godunov. Rarely the tragedy was enthusiastically greeted by small part of intellectuals, for example P.Vjazemskij. Czar Nikolaj and the critic F.Bulgarin cynically criticized the tragedy. The critical attitude to Boris Godunov continued long time. After the October Revolution in the 20th century the tragedy of Puschkin was performed on the theatre stage. My paper study many problems: Puschkin’s Dramaturgy, three unity, composition of tragedy. My next study is the relationship of Puschkin and Shakespeare, Boris Godunov and the epic theatre of B. Brecht.
