Using the pen name Mark Twain, Samuel Clemens had become one of this country's favorite satiric writers by the early 1870s, routinely making light of everyday human foibles. But it was the publication of The Adventures of Tom Sawyer (1876) and The Adventures of Huckleberry Finn (1884) that assured him a lasting place in American letters. Inspired in part by his own boyhood, these two tales set along the Mississippi River did more than capture the rhythms of youth in antebellum America. In both novels, Clemens examined with sardonic wit various tensions that underlay contemporary society, including, most importantly, the question of race. In later years, his success in this country and abroad was tempered by financial and personal setbacks and by a contempt for American and British imperialism.
