How did Charles Dickens’s American visit influence American Notes and Martin Chuzzlewit?

Charles Dickens’s five-month tour of the United States in 1842 profoundly shaped his subsequent writing, as he found the reality of the "republic of his imagination" to be a disappointment filled with vulgarity and sharp practice rather than the social ideals he had anticipated.12

In his nonfiction book American Notes, Dickens documented his experiences, using the platform to launch a vigorous attack on the institution of slavery and to protest the lack of copyright protection, which allowed American publishers to sell millions of his books without providing him royalties.12

These frustrations also permeated his novel Martin Chuzzlewit. Dickens incorporated American episodes into the story, partly as a calculated move to boost declining sales through "America-baiting" and partly to seek literary revenge against the American press. In the novel, the protagonist and his servant travel to the United States, where they are swindled by land speculators and endure unpleasant experiences, ultimately leading them to return to England, thoroughly disillusioned with the New World.34
