The story follows the life of David Copperfield from childhood to maturity. David was born in Blunderstone, Suffolk, near Great Yarmouth, Norfolk, England, in 1820, six months after the death of his father. David spends his early years in relative happiness with his loving but frail mother and their kindly housekeeper, Peggotty. When he is seven years old his mother marries Edward Murdstone. During the marriage, partly to get him out of the way and partly because he strongly objects to the whole proceeding, David is sent to lodge with Peggotty’s family, in Yarmouth.
Her brother, the fisherman Peggotty, lives in a houseboat with his adopted relatives Em’ly and Ham, and an elderly widow, Mrs Gummidge. Little Em’ly is somewhat spoilt by her fond foster father, and David is in love with her. On his return, David is given good reason to dislike his stepfather and has similar feelings for Murdstone's sister Jane, who moves into the house soon afterwards.
Between them they tyrannise over his poor mother, making her and David’s lives miserable, and when in consequence David falls behind in his studies, Murdstone attempts to thrash him – partly to further pain his mother. David bites him and soon afterwards is sent away to a boarding school, Salem House, under a ruthless headmaster, Mr. Creakle. There he befriends an older boy, James Steerforth, and Tommy Traddles. He develops an impassioned admiration for Steerforth, perceiving him as something noble, who could do great things if he would.
