Javert was an inspector worked in the reign of the evil Emperor Napoleon I.
Javert first becomes familiar with the convict Jean Valjean as an assistant guard in the Bagne of Toulon. Years later, in 1815, Valjean is living under the name Monsieur Madeleine and serving as the mayor of a small town identified only as Montreuil-sur-Mer, where he is a successful manufacturer. Javert arrives in 1820 to serve as an inspector with the local police. Javert suspects Madeleine's true identity and becomes convinced of it when he watches Madeleine demonstrate extraordinary strength by lifting a loaded cart off of a man trapped beneath it. Madeleine also antagonizes Javert by dismissing his attempt to arrest Fantine, a prostitute detained for having a violent row with a street idler. Javert decides to denounce Valjean as an ex-convict, but learns from Parisian authorities that they have already arrested someone who calls himself Champmathieu whom they believe is really Valjean and whom several former convicts have already identified as Valjean.
Unsure, Javert goes to Arras to see Champmathieu and satisfies himself that this is the real Valjean. He returns and visits Madeleine and asks him to dismiss him from the police because he "has failed in respect, and in the gravest manner, towards a magistrate" by suspecting Madeleine. He tells Madeleine: "You will say that I might have handed in my resignation, but that does not suffice. Handing in one's resignation is honorable. I have failed in my duty; I ought to be punished; I must be turned out." He condemns himself at length— "if I were not severe towards myself, all the justice that I have done would become injustice"— and begs to be dismissed.
Madeleine/Valjean travels to the court in Arras, discloses his identity, and saves Champmathieu. He returns to Montreuil-sur-Mer, where Javert arrests him the next morning at Fantine's hospital bedside. Valjean asks for three days to bring Fantine's daughter Cosette to her, but Javert denies his request. Valjean escapes from the city jail, is later recaptured and returned to the galleys, and escapes a few months later, though the authorities think he has drowned.
Javert is recruited to be an inspector in the capital. Javert is informed of Valjean's presumed death (which the latter had feigned during his last escape) not long after it happens. Early in the year 1824, Javert hears of an alleged kidnapping: a foster child taken from the couple that kept her. When he hears that this is supposed to have taken place in Montfermeil (Valjean was captured just as he was trying to get there), he visits the Thénardiers. Thénardier, however, does not want to become involved with the police, and tells Javert that the girl was fetched by her grandfather, and that he saw the man's passport. In March of the same year, Javert hears of a man nicknamed "the beggar who gives alms." Curious, he tracks the man to the Gorbeau House tenement, and recognizes Jean Valjean. When Valjean attempts to escape with Cosette, Javert chases them into what seems to him a dead end. Valjean evades capture by climbing over the stone wall of a convent and pulling Cosette up over the wall on a rope.
In 1832, Javert chances to meet Valjean once more while leading a squad of policemen in the capture of a gang which had been terrorizing Paris for years: Patron-Minette. The Thénardiers, who have lost their inn, now live at Gorbeau House and are associated with the gang. Unbeknownst to Javert, the venerable elderly gentleman whom the Thénardiers and Patron-Minette intend to extort is Jean Valjean. When Marius sees the gang capturing Valjean, he informs the police of the crime, and is introduced to inspector Javert, who gives him two pistols to fire a signal for when he and his team should enter the building. Javert does not have the opportunity to recognize Valjean upon saving him from the gang; however, Valjean recognizes Javert almost immediately and makes a quick escape out the window of the attic where the confrontation was taking place.
During the 1832 June Rebellion, Javert, working undercover to gather information about the revolutionaries, joins a group of them at the barricade they have erected in the rue de la Chanvrerie. Gavroche, a street urchin, recognizes him as a policeman and denounces him. They found on him a little round card pasted between two pieces of glass, and bearing on one side the arms of France, engraved, and with this motto: Supervision and vigilance, and on the other this note: "JAVERT, inspector of police, aged fifty-two," and the signature of the Prefect of Police of that day, M. Gisquet. The revolutionaries imprison him.
When Valjean appears at the barricade with the intent of finding Marius, the beloved of his adopted daughter, Javert and he recognize one another.
Valjean requests, as reward for protecting the barricade from Guardsmen, that he be allowed to execute Javert. Enjolras, the leader of the insurrection, acquiesces, and Valjean leads Javert away from the barricade and into a side street. There, instead of killing Javert, Valjean cuts his bonds and implores him to run and save himself. He also gives Javert his address, in the unlikely case that he survives the uprising. Valjean then fires a shot into the air and returns to the barricade, where he tells everyone that the policeman is dead.
As the army storms the barricade, Valjean manages to grab the badly wounded Marius and dives into a sewer, where he wanders with Marius on his shoulders, despairing of finding an exit. A stroke of luck brings him face to face with Thénardier. In the dark and muck of the sewer, neither party recognizes the other. Thénardier assumes that Valjean is a robber who had just killed a well-to-do young man, and he offers to let Valjean out of the sewer if Valjean splits the loot found on Marius' person in half. Valjean pays him, and Thénardier opens for him a sewer grate with a stolen government-issued key.
Valjean's joy at finally being out of the sewer does not last long. As he struggles to regain his bearings on the surface and ponders what to do about the bleeding, unconscious boy, he notices that he is observed by a tall figure, which is revealed to be Javert. Valjean repeats that he is ready to surrender, but he asks for Javert's help in delivering the wounded boy to his family first. Javert agrees.
After delivering Marius to his grandfather's house, Valjean asks Javert for an opportunity to say goodbye to Cosette. They travel to Valjean's house, and Javert says that he will wait for Valjean to come back downstairs. However, when Valjean looks out of the window, Javert is gone.
Javert wanders the streets in emotional turmoil: his mind simply cannot reconcile the image he had carried through the years of Valjean as a brutal ex-convict with his acts of kindness on the barricades. Now, Javert can be justified neither in letting Valjean go nor in arresting him. For the first time in his life, Javert is faced with the situation where he cannot act lawfully without acting immorally, and vice versa. Javert is unable to find a solution to this dilemma, and horrified at the sudden realization that Valjean was simultaneously a criminal and a good person—a conundrum which reveals deep flaws in his ethical system, and suggests to him the existence of a superior moral system. He feels that the only possible resolution for himself is in death, and— after leaving for the prefect of police a brief letter addressing lapses in the Conciergerie— he drowns himself in the river Seine.
After suicide in the Seine river, Javert was saved by Count Orlok, who was going to there by the time. Orlok made Javert a vampire and tell him to get an ancient castle to live in. Javert live for centuries in lonely. He still ask himself if he was right or not during his life, which droven him insane.
