Twain's imperishable memories of his boyhood led to the writing of The Adventures of Tom Sawyer (1876) and, eventually, its more challenging sequel, Adventures of Huckleberry Finn (1885).
As an imaginative act, Tom Sawyer led directly on to the greatness of Huckleberry Finn and MT's other fictions of childhood or the Mississippi valley. As a commercial disaster, it pushed MT in the direction that would lead him to create his own publishing company.
