Tolstoy's lasting contribution to Russian literature was a trilogy of historical dramas (modelled after Alexander Pushkin's "Boris Godunov"): "The Death of Ivan the Terrible", "Tsar Fyodor Ioannovich", and "Tsar Boris". "The Death of Ivan the Terrible", published in 1866 in "Otechestvennye Zapiski" magazine, was staged the following year in Saint Petersburg, Moscow, and some provincial theaters and enjoyed massive success, but after 1870 was virtually banned and got revived on stage only in the late 1890s. "Tsar Fyodor Ioannovich" (1868, "Vestnik Evropy") was banned from being produced on stage personally by Interior minister Timashev; as late as 1907 censors deemed the play "inappropriate." "Tsar Boris" (1870, "Vestnik Evropy") received no official ban, but the Directorial council of the Imperial Theatres refused to sanction its production. In 1871 Tolstoy started his fifth and final play called "Posadnik" (set in the times when the Novgorod Republic prospered), which remained unfinished. Parts of it were published in "Skladchina", an 1874 charity almanac, the rest appeared in "Vestnik Evropy" in 1876, after the author's death.
