Uncle Tom’s Cabin was the best-selling novel of the 19th century (and the second best-selling book of the century after the Bible) and is credited with helping to fuel the abolitionist cause in the 1850s. In the first year after it was published, 300,000 copies of the book were sold. Page 226 of Robert J. Scarry’s “Millard Fillmore” states that “Uncle Tom’s Cabin” was the first American novel to sell one million copies and that Millard Fillmore had two copies of this book.
