Vanity Fair: A Novel without a Hero is a novel by William Makepeace Thackeray that satirizes society in early 19th-century England. Like many novels of the time, Vanity Fair was published as a serial before being sold in book form; it was printed in 20 monthly parts between January 1847 and July 1848.
Thackeray meant the book to be not only entertaining but also instructive; this is shown both by the narrator of the book and in Thackeray’s private correspondence. (Summary from Wikipedia)
