Rebecca "Becky" Sharp, later describing herself as Rebecca, Lady Crawley, is the main protagonist of William Makepeace Thackeray's 1847–48 novel Vanity Fair. She is presented as a cynical social climber who uses her charms to fascinate and seduce upper-class men. This is in contrast with the clinging, dependent Amelia Sedley, her friend from school. Becky then uses Amelia as a stepping stone to gain social position. Sharp functions as a picara—a picaresque heroine—by being a social outsider who is able to expose the manners of the upper gentry to ridicule.
