Fanny Price is a young girl from a large and relatively poor family, who is taken from them at age 10 to be raised by her rich uncle and aunt, Sir Thomas, a baronet, and Lady Bertram, of Mansfield Park. She had previously lived with her own parents, Lieut. Price and his wife, Frances (Fanny), Lady Bertram's sister. She is the second child and eldest daughter, with seven siblings born after her. She has a firm attachment to her older brother, William, who at the age of 12 has followed his father into the navy. With so many mouths to feed on a limited income, Fanny's mother is grateful for the opportunity to send Fanny away to live with her fine relatives.

More than eight years before the novel opens, Anne Elliot, then a lovely, thoughtful, warm-hearted 19 year old, accepted a proposal of marriage from the handsome young naval officer Frederick Wentworth. He was clever, confident, and ambitious, but poor and with no particular family connections to recommend him. Sir Walter, Anne's fatuous, snobbish father and her equally self-involved older sister Elizabeth were dissatisfied with her choice, maintaining that he was no match for an Elliot of Kellynch Hall, the family estate. Her older friend and mentor, Lady Russell, acting in place of Anne's late mother, persuaded her to break the engagement. Now 27 and still unmarried, Anne re-encounters her former love when his sister and brother-in-law, the Crofts, take out a lease on Kellynch. Wentworth is now a captain and wealthy from maritime victories in the Napoleonic wars. However, he has not forgiven Anne for rejecting him. While publicly declaring that he is ready to marry any suitable young woman who catches his fancy, he privately resolves that he is ready to become attached to any appealing young woman except for Anne Elliot.

The story follows the main character Elizabeth Bennet as she deals with issues of manners, upbringing, morality, education, and marriage in the society of the landed gentry of early 19th-century England. Elizabeth is the second of five daughters of a country gentleman living near the fictional town of Meryton in Hertfordshire, near London.
