Major
Jean Valjean (also known as Monsieur Madeleine, Ultime Fauchelevent, Monsieur Leblanc, and Urbain Fabre) – The protagonist of the novel. Convicted for stealing a loaf of bread to feed his sister's seven starving children and sent to prison for five years, he is paroled from prison nineteen years later (after four unsuccessful escape attempts added twelve years and fighting back during the second escape attempt added two extra years). Rejected by society for being a former convict, he encounters Bishop Myriel, who turns his life around by showing him mercy and encouraging him to become a new man. While sitting and pondering what Bishop Myriel had said, he puts his shoe on a forty-sou piece dropped by a young wanderer. Valjean threatens the boy with his stick when the boy attempts to rouse Valjean from his reverie and recover his money. He tells a passing priest his name, and the name of the boy, and this allows the police to charge him with armed robbery – a sentence that, if he were caught again, would return him to prison for life. He assumes a new identity (Monsieur Madeleine) in order to pursue an honest life. He introduces new manufacturing techniques and eventually builds two factories and becomes one of the richest men in the area. By popular acclaim he is made mayor. He confronts Javert over Fantine's punishment, turns himself in to the police to save another man from prison for life, and rescues Cosette from the Thénardiers. Discovered by Javert in Paris because of his generosity to the poor, he evades capture for the next several years in a convent. He saves Marius from imprisonment and probable death at the barricade, reveals his true identity to Marius and Cosette after their wedding, and is reunited with them just before his death, having kept his promise to the bishop and to Fantine, the image of whom is the last thing he sees before dying.
Javert – A fanatic police inspector in pursuit to recapture Valjean. Born in the prisons to a convict father and a fortune teller mother, he renounces both of them and starts working as a guard in the prison, including one stint as the overseer for the chain gang of which Valjean is part (and here witnesses firsthand Valjean's enormous strength and just what he looks like). Eventually he joins the police force in the small town identified only as M____-sur-M__. He arrests Fantine and butts heads with Valjean/Madeleine, who orders him to release Fantine. Valjean dismisses Javert in front of his squad and Javert, seeking revenge, reports to the Police Inspector that he has discovered Jean Valjean. He is told that he must be incorrect, as a man mistakenly believed to be Jean Valjean was just arrested. He requests of M. Madeline that he be dismissed in disgrace, for he cannot be less harsh on himself than on others. When the real Jean Valjean turns himself in, Javert is promoted to the Paris police force where he arrests Valjean and sends him back to prison. After Valjean escapes again, Javert attempts one more arrest in vain. He then almost recaptures Valjean at Gorbeau house when he arrests the Thénardiers and Patron-Minette. Later, while working undercover behind the barricade, his identity is discovered. Valjean pretends to execute Javert, but releases him. When Javert next encounters Valjean emerging from the sewers, he allows him to make a brief visit home and then walks off instead of arresting him. Javert cannot reconcile his devotion to the law with his recognition that the lawful course is immoral. He takes his own life by jumping into the Seine.
Fantine – A beautiful Parisian grisette abandoned with a small child by her lover Félix Tholomyès. Fantine leaves her daughter Cosette in the care of the Thénardiers, innkeepers in the village of Montfermeil. Mme. Thénardier spoils her own daughters and abuses Cosette. Fantine finds work at Monsieur Madeleine's factory. Illiterate, she has others write letters to the Thénardiers on her behalf. A female supervisor discovers that she is an unwed mother and dismisses her. To meet the Thénardiers' repeated demands for money, she sells her hair and two front teeth, and turns to prostitution. She becomes ill. Valjean learns of her plight when Javert arrests her for attacking a man who called her insulting names and threw snow down her back, and sends her to a hospital. As Javert confronts Valjean in her hospital room, because her illness has made her so weak, she dies of shock after Javert reveals that Valjean is a convict and hasn't brought her daughter Cosette to her (after the doctor encouraged that incorrect belief that Jean Valjean's recent absence was because he was bringing her daughter to her).
Cosette (formally Euphrasie, also known as "the Lark", Mademoiselle Lanoire, Ursula) – The illegitimate daughter of Fantine and Tholomyès. From approximately the age of three to the age of eight, she is beaten and forced to work as a drudge for the Thénardiers. After her mother Fantine dies, Valjean ransoms Cosette from the Thénardiers and cares for her as if she were his daughter. Nuns in a Paris convent educate her. She grows up to become very beautiful. She falls in love with Marius Pontmercy and marries him near the novel's conclusion.
Marius Pontmercy – A young law student loosely associated with the Friends of the ABC. He shares the political principles of his father and has a tempestuous relationship with his royalist grandfather, Monsieur Gillenormand. He falls in love with Cosette and fights on the barricades when he believes Valjean has taken her to London. After he and Cosette marry, he recognizes Thénardier as a swindler and pays him to leave France.
