Russian Count Aleksey Konstantinovich Tolstoy or Alexei Tolstoy, best known as A.K. Tolstoy (1817-1875), was a Russian poet, novelist, and satirist, a member of the famous Tolstoy family, and a second cousin to Leo Tolstoy. During his childhood, A.K. was "a comrade in games" with the future Crown Prince, Alexander II.
Tostoy was regarded as the best historical dramatist in Russia in the 19th century for his trilogy: The Death of Ivan the Terrible (1866), Tsar Fyodor Ioannovich (1868), and Tsar Boris (1870).
