Joffrey ruled the Seven Kingdoms, having claimed the Iron Throne after his father, King Robert Baratheon, died. However, Joffrey was actually the bastard son of the incestuous relationship between Ser Jaime Lannister and Queen Cersei Lannister. Because of this, his claim to the Iron Throne was challenged by Robert's younger brother, Stannis Baratheon. He was formally styled as His Grace, Joffrey of the Houses Baratheon and Lannister, the First of His Name, King of the Andals and the First Men, Lord of the Seven Kingdoms, and Protector of the Realm.
Joffrey was originally betrothed to Sansa Stark, whom he kept captive in King's Landing after he beheaded her father for treason, as Eddard Stark tried to reveal the truth about his parentage. However, he later set Sansa aside in favor of Margaery Tyrell, as part of the new alliance between House Lannister, the primary supporters of Joffrey, and House Tyrell, the ruling house of the Reach whose support helped save King's Landing from Stannis Baratheon's attack.
At his wedding to Margaery Tyrell, Joffrey was assassinated by poison after drinking from his wine goblet. His final gesture as he was dying was towards his uncle, Tyrion Lannister. Upon his death, Cersei Lannister arrests Tyrion on the grounds of regicide, though the actual orchestrators are Lord Petyr Baelish and Lady Olenna Tyrell.
Joffrey is believed to be the oldest son and heir of King Robert Baratheon and Queen Cersei Lannister, both of whom entered into a political marriage alliance after Robert took the throne by force from the Mad King Aerys II Targaryen. In reality, his father is Jaime Lannister, the queen's brother and the Lord Commander of the Kingsguard. He has a younger sister, Myrcella, and a younger brother, Tommen , both whom are also the product of Jaime and Cersei's incest.
Joffrey takes after his mother in terms of looks and personality, his blonde hair being a subtle clue that he isn't really a Baratheon, who famously always possess black hair even when one of their parents possesses blonde hair. He is usually accompanied by his sworn shield, the formidable Sandor Clegane, who is better known as the Hound. Even before he ascends to the Iron Throne, Joffrey is spoiled, arrogant, cowardly, and sadistic; however these traits are further exacerbated upon Robert's death and his ascension to the crown.
Prince Joffrey accompanies his parents to Winterfell and is betrothed to marry Sansa Stark as part of King Robert's plan unite House Baratheon to House Stark by blood. Both seem happy with the prospect, and Joffrey is charming and polite towards Sansa. However, he shows no sympathy when Bran falls from a tower and is severely injured, and has to be physically chastised by his uncle Tyrion before he will pay his respects to Bran's parents. While on the Kingsroad to King's Landing, Joffrey is walking with Sansa and chances upon her sister Arya practicing sword play with a commoner, Mycah. Joffrey sees a chance to have some fun with Mycah, who is too scared to move. Joffrey accuses him of assault on a noble girl and makes a cut on his face with his sword, but Arya hits Joffrey, allowing the butcher's boy to get away. When Joffrey turns on Arya, her direwolf Nymeria overpowers Joffrey, injuring him, and Arya throws his sword in the river. Joffrey begs for his life. Sansa offers aid, but Joffrey is angry at her because she saw him weak and defeated. Later, he lies about the incident and says he was attacked in an unprovoked manner. King Robert knows Joffrey is lying, and is disgusted that Joffrey let a little girl disarm him, but agrees to forget about the incident in return for the death of Nymeria. When she cannot be found, Sansa's direwolf Lady is executed instead.
In King's Landing, Joffrey tells his mother about how he would handle the people of the North as she treats his injury. He suggests capturing Winterfell, taxing the people hard and forcing their warriors to join a "royal army". Cersei elucidates the flaws in his plan and warns Joffrey that a king needs to be more careful in choosing his battles. Cersei tells her son that, "Everyone who isn't us is an enemy". She also urges Joffrey to do something nice for Sansa to win back her goodwill.
Eddard Stark discovers that Joffrey isn't King Robert's son and rightful heir, by examining the family history and realizing that black hair is a dominant trait in the Baratheon line. Eddard realizes that Joffrey's true parentage can be attributed to the incestuous relationship between his mother and his "uncle" Jaime Lannister. Meanwhile, Joffrey wins back Sansa's affection by giving her a pendant
When King Robert Baratheon is grievously wounded in a hunting injury, he talks to Joffrey on his death bed and says he could have been a better father. Joffrey ascends the Iron Throne. He orders that preparations be made to crown him within the fortnight. Eddard refuses to recognize Joffrey's claim to the Iron Throne. He presents a proclamation from Robert making him Regent and Protector of the Realm to enforce his authority, but Cersei tears up the document. Eddard expects Lord Petyr Baelish and Commander Janos Slynt of the City Watch to take Cersei and Joffrey prisoner, but is betrayed. Eddard is taken into custody and his remaining guards and household are murdered.
Sansa is taken captive as well, but Arya manages to escape into the city. Joffrey dismisses Ser Barristan Selmy from the Kingsguard and names his "uncle" Jaime as the new Lord Commander. Barristan is shocked, as the Kingsguard are sworn to serve for life, and it is legally impossible to dismiss one of their members. Joffrey listens to Sansa's pleas for her father, and he agrees to show mercy to Lord Eddard if he admits treason and recants his claim that Joffrey has no right to the throne. Sansa is sure that he will.
offrey is present at the Great Sept of Baelor for Eddard's public trial where, due to threats to Sansa's life, he confesses to treason and acknowledges Joffrey as the true king. Joffrey, playing to the crowd, reveals that his mother and his betrothed have both urged him to spare Eddard's life and exile him to the Wall (this deal had been worked out involving Queen Cersei, Varys, Grand Maester Pycelle, the High Septon, and Yoren waiting in the crowd to take him in custody). Joffrey had been told to spare him, but surprises everyone by saying that his mother and betrothed have the weak hearts and constitutions of women, whilst he has no mercy for traitors. He orders Ser Ilyn Payne to bring him Eddard's head. Payne carries out the order, whilst Sansa faints from shock and Cersei - aware this will fuel the war with the Starks - angrily tries and fails to overrule her son. Days later, Joffrey holds court. Marillion sings a song he wrote about King Robert and Queen Cersei, which includes lyrics saying that the boar may have disemboweled Robert, but the "lion in his bed" (the Lannister's sigil is a lion) was the one who tore his balls off. Joffrey is displeased by the song and its insults against his parents. He forces the minstrel to choose between having his hands or tongue removed, then orders Ser Ilyn to instantly carry out the order, ripping out his tongue in front of the entire horrified court. Joffrey and his guards escort Sansa out of the courtroom and he states to her that she will be kept captive there and will still marry him; he also casually mentions that his mother said he should "put a son in you" as soon as Sansa has had her blood. They arrive at the castle's wall, where there are several heads mounted on long spikes - one is revealed to be Ned's. When Sansa is appalled, Joffrey angrily points to another spike carrying the head of Septa Mordane, revealing that he also needlessly killed Sansa's own Septa. She confronts him about his promise to show mercy to her father, but he says it was mercy, as he gave him a quick death. Then Joffrey forces her to look at the severed heads, and he says that he will give her Robb's head on a spike as well if he were to be defeated by the Lannisters, prompting her to reply: "Or maybe he'll give me yours."
Joffrey is infuriated, but restrains himself from striking her as he says "Mother tells me a king should never strike his lady" - so he simply calls on Ser Meryn Trant to strike her for him, and the knight slaps Sansa hard across the face twice. Sansa comes up behind Joffrey on the walkway, obviously thinking of pushing him, though it would mean her death. The Hound realizes this and stops her, under the pretense of wiping the blood off her lip.
Joffrey rules with cruelty and arrogant whims while his grandfather Tywin Lannister fights in the War of the Five Kings to secure his hold of the Iron Throne. Joffrey celebrates his nameday with a tourney and continues to torment the captive Sansa Stark, also naming Ser Dontos Hollard as his new fool as punishment to showing up drunk. He is perturbed when his uncle Tyrion Lannister is made acting Hand of the King. Rumors about his parentage begin to circulate and he confronts his mother, Queen Regent Cersei Lannister with them. He asks her about King Robert Baratheon's bastard children and she slaps him. He threatens her life and then arranges for a city wide massacre of the bastards. Tyrion responds by exiling Janos Slynt and installing Bronn as the replacement Lord Commander of the City Watch.
Robb Stark continues to win victories against Joffrey's Lannister allies. Furious, Joffrey has Sansa Stark brought into the throne room. Before the whole court, he demands she answer for her brother's treason and threatens to kill her with a crossbow. Instead he orders Meryn Trant to strip and beat her. Tyrion interrupts the proceedings and scolds Joffrey for his behavior, as Sansa is his future queen. When Joffrey retorts that as king he can do whatever he wishes, his uncle reminds him that the mad king thought he could do whatever he wanted as well, and ended up being overthrown
Talking to Bronn, Tyrion decides that Joffrey is at an age when sexual frustration might be an issue, and this could be one reason for his torment of Sansa. He then sends Joffrey two prostitutes, Ros and Daisy, as a belated nameday present. Joffrey forces one prostitute to brutally beat the other as a message to Tyrion that he will tolerate no further interference.
Joffrey attends the departure of his sister Myrcella Baratheon for Dorne as part of a marriage alliance pact. Joffrey is confronted by an angry populace as he makes his way back to the Red Keep. One onlooker throws some cow dung at him and Joffrey triggers a city wide riot by ordering his heavily outnumbered guards to kill everyone in the crowd. He barely escapes the riot under the protection of his Kingsguard and Tyrion publicly berates him for being a "vicious idiot". When they realize Sansa has been lost in the chaos, Joffrey callously commands that she be left to the mob; Tyrion has to point out that if any harm comes to Sansa then his uncle Jaime, a prisoner of the Starks, will be killed in retaliation.
King Stannis Baratheon sails on King's Landing with a fleet of over 200 ships. Joffrey is determined to fight personally, scaring his mother. Cersei suspects that Tyrion is encouraging Joffrey and plots to blackmail him into ensuring Joffrey's safety by imprisoning his lover. Joffrey tours the sea wall of the city with Tyrion and insists that he will kill Stannis himself. His bravado is undercut by his woeful lack of appreciation of the danger he is in; he stupidly suggests that they should be planning to assault Robb rather than defending their capital.
Joffrey procures a new sword for the Battle of the Blackwater, naming it "Hearteater." He forces Sansa to meet him in the Throne Room before going to the city walls, making her kiss the blade and claiming that when he returns it will have Stannis' blood on it. Sansa carefully undermines his claim by questioning if he will fight in the vanguard. Joffrey is frustrated by not being made aware of Tyrion Lannister's plans to defend the city and angrily threatens his uncle. The absence of the Royal Fleet frightens Joffrey. He is pleased when Tyrion's wildfire explosion decimates Stannis' fleet. However, his courage wanes when he sees the size of the landing force that comes ashore. A sortie led by the Hound fails to drive the attackers back. The Hound then deserts his place on the Kingsguard rather than go back out. Joffrey is relieved when Ser Lancel Lannister tells him that the Queen has ordered him back to the Red Keep and ignores Tyrion imploring him to stay and lead. His cowardly exit damages the morale of the men but Tyrion is able to rally them into a further sortie, protecting the gates from a battering ram. Tyrion is wounded during the fighting but the battle is won by the arrival of a host of House Lannister and House Tyrell soldiers under the command of Lord Tywin Lannister.
Joffrey rewards Tywin by naming him Savior of the City. He also grants a favor to House Tyrell for their aid and Ser Loras asks Joffrey to unite their houses in marriage. Joffrey balks at setting aside his betrothal to Sansa, but is easily convinced in a sham dialogue with his mother and courtiers and agrees to marry Margaery Tyrell.
King Joffrey is passing through Flea Bottom in a heavily guarded palanquin. The Riot of King's Landing recently occurred in this part of the city. His convoy suddenly stops moving because his betrothed Margaery Tyrell insists on interacting with the smallfolk and visiting an orphanage. Later that night, he has dinner with Margaery, her brother Loras, and his mother Cersei. Cersei tells Margaery that the king barely survived the recent riot, but Joffrey explains that they were not in any real danger. He also defends Margaery's actions, to Cersei's discomfort.
While fitting clothes in his chambers, Cersei asks Joffrey what he thinks about Margaery, and he says the alliance with the Tyrells will help them defeat the northern rebellion. Cersei asks what he thinks about her personally, but Joffrey dismisses her questions. Later, Joffrey summons Margaery to his chambers. Joffrey is holding his new crossbow and asks why she was married to traitor Renly Baratheon and why she failed to give him a child. Margaery tells Joffrey that she doesn't believe Renly was interested in women. Joffrey says he is considering making homosexuality punishable by death. He then demonstrates to Margaery how to use a crossbow.
Joffrey, Margaery, Cersei, and Olenna Tyrell are visiting the Great Sept of Baelor, where the royal wedding will be held. Joffrey tells Margaery about the history of the dead Targaryen kings. Margaery feigns interest, then they hear a crowd of smallfolk outside. Margaery suggest they greet them, and Joffrey is reluctant but has the doors opened. Joffrey and Margaery step outside to a happy, cheering crowd, while Cersei looks on angrily.
Ros is caught spying on Lord Petyr Baelish, so Lord Baelish gives her to Joffrey, who brutally kills her in his chambers with his crossbow.
Joffrey summons his Hand Tywin Lannister to the throne room. Joffrey asks for a report of the small council meetings, and Tywin invites him to attend the small council meetings. Joffrey complains that Tywin holds the meetings in the Tower of the Hand, which requires him to climb many stairs. Joffrey squirms as Tywin approaches the throne, and Tywin tells him that he can be carried to the tower. Joffrey then asks for information on the rumors about Daenerys Targaryen and her dragons. Tywin confirms the rumors are true, and Joffrey demands to know what is being done about it. Tywin tells him it is not his concern, and he should leave such matters to his advisers.
At the wedding of Tyrion Lannister and Sansa Stark, Joffrey escorts Sansa to the altar. He then removes Tyrion's stool, so he cannot reach Sansa's shoulders to cloak her. Joffrey laughs when Tyrion is unable to cloak her. When Sansa excuses herself from her table during the feast, Joffrey follows her, and suggests he might pay a visit to her chambers that night after Tyrion passes out. Joffrey then calls for the bedding ceremony, and Tyrion insists there will be no bedding ceremony. Tyrion threatens the king, which infuriates Joffrey. Tywin says they can do without the bedding ceremony, and Tyrion says he was only joking, feigning being drunk so as not to anger Joffrey to the point where he might order harm upon him.
At a meeting of the small council, Joffrey gleefully informs Tyrion of the deaths of Robb Stark and Catelyn Stark. He tells Grand Maester Pycelle to thank Walder Frey for his service and wants to serve Robb's head to Sansa at his wedding feast. Lord Varys and Tyrion take offense to this, and Tyrion threatens the king again. Tywin interjects by saying that he has won Joffrey's war for him. Joffrey angrily states that his supposed father won the real war, while Tywin hid in Casterly Rock during the fighting. Tywin orders that Joffrey be put to bed, and given Essence of Nightshade to sedate him. Joffrey is taken to his chambers by Cersei.
With King Joffrey basking in his "glory", he is not very interested in planning his own wedding. Joffrey insists to Jaime Lannister that the people of King's Landing know that he "saved the city" in the Battle of Blackwater and they know that he "won" the War of the Five Kings, and is convinced that there will not be a riot at the wedding.
At a breakfast celebration on his wedding day, Joffrey receives various gifts. Among them, he is given a book by his uncle Tyrion, and a Valyrian steel sword forged from Ned Stark's sword Ice by his grandfather Tywin. Pleased with the gift, he promptly destroys the book with his new sword, to the horror of his guests. He says the sword needs a name; one guest suggests Widow's Wail, which gets Joffrey's approval.
In the Sept of Baelor at the purple wedding celebration, Joffrey and Margaery are wed. At the wedding feast, a band plays The Rains of Castamere; Joffrey throws money them and tells them to go away. Later, Dontos Hollard performs in front of the royal family and Joffrey promises a gold dragon to whoever knocks Dontos' hat off which leads to many objects hurling at his head. Joffrey then announces some entertainment that he has organized: a group of dwarfs crudely re-enacting the War of the Five Kings and fighting each other. Joffrey laughs hysterically during the show, spitting wine all over himself, though many others in attendance clearly find the spectacle distasteful.
Once the dwarf show is over, Joffery turns his attention to Tyrion and suggests he borrow a costume and join in. Tyrion politely declines and suggests that the King himself take part, with a veiled reference to Joffrey's cowardice at the Battle of the Blackwater. Joffrey responds by pouring his wine over Tyrion's head and appointing Tyrion his new cupbearer. As the crowd watch in stunned silence, Joffrey drops his goblet and orders Tyrion to pick it up, then kicks it away and tells Tyrion to pick it up again. Joffrey demands that Tyrion kneel before him. Tyrion silently refuses. The stand off is interrupted by the arrival of the big wedding pie, which is cut by Joffrey with Widow's Wail, and doves come flying out of it.
While Joffrey is eating his pie, he commands Tyrion to stay to bring him his wine. Tyrion does this and asks to leave, which Joffrey refuses. After drinking his wine, Joffrey starts choking violently. As he gasps for air he staggers down from the high table and starts vomiting on the floor. Jaime runs from the crowd, and Cersei from the high table. Cersei holds her son in her lap. His face has turned purple, and blood is running from his eyes and nose. With a last gesture, Joffrey looks up at Tyrion, who has picked up the goblet to examine it for poison, lifts an accusing finger in his direction, and then dies of asphyxiation. Cersei immediately accuses Tyrion of poisoning her son and demands that he be arrested.
Joffrey's funeral is held at the Great Sept of Baelor, which Cersei, Tommen and Tywin attend to pay their respects. Tywin informs Tommen that with Joffrey's death, the crown will pass to him. Over Joffrey's corpse, Tywin lectures Tommen on what it takes to be a good king, despite Cersei's feeble complaints that this is neither the time nor the place for this. He opines that Joffrey was neither a wise nor a good king, and that had he been, he may still be alive. After Tywin leaves and Jaime arrives, Cersei is adamant that it was Tyrion who killed Joffrey, and asks Jaime to kill him to avenge their son. Jaime scornfully asks why he was forced to love such a hateful woman, and they angrily have sex in front of their son's corpse.
After Joffrey's death, his younger brother Tommen is crowned king.
Over-indulged and cowardly, king Joffrey exhibited a cruel streak toward the vulnerable - a trait for which his uncle Tyrion has little patience. Tyrion now stands accused of murdering Joffrey at his wedding celebration.
Joffrey was cruel, arrogant, sadistic, and a tyrannical ruler. However, he was also incompetent, unintelligent, naive, petulant, cowardly, and prone to rash outbursts of violence. Much like earlier Targaryen kings, it was suspected that Joffrey's psychopathy was a result of his incestuous bloodline. Nonetheless, Joffrey was consumed by megalomaniacal delusions of grandeur. Even though he was absurdly unskilled at ruling, making far more problems than he solved, he was convinced that he deserved praise and utter devotion from everyone around him. Despite the fact that at the start of the War of the Five Kings most of the realm rose in rebellion against him, to the point that his faction essentially controlled only the Westerlands, the Crownlands, and a narrow strip of the southern Riverlands between them, Joffrey was convinced that he was the greatest king in the history of the Seven Kingdoms. Added to what was an unstable personality to begin with, Cersei utterly spoiled and indulged Joffrey his entire life, resulting in him possessing a massive sense of entitlement which knows no emotional bounds.
Joffrey was deceitful, but showed even less tact than his mother. He was willing to take advantage of the trust that Sansa Stark initially placed in him, when she was blinded by fantasies of marrying her handsome prince. In general, however, Joffrey was usually too short-sighted to bother lying, often simply committing various atrocities in public, without concern for the consequences.
Joffrey was obsessed with the self-conception that he was a great warrior like King Robert, but displayed no martial skill. Particularly, despite the fact that his faction was losing the war and bracing for a siege in King's Landing, Joffrey insisted that now was the time to "strike" against Robb Stark, at which Tyrion had to point out that his own city was on the verge of attack by Stannis's superior forces.
Aptly described as a vicious idiot, Joffrey was not simply a ruthless king, but absurdly incompetent. While Robert was also not skilled at ruling (though not as bad as Joffrey), he was at least respected as a great warrior. Joffrey, in contrast, had no redeeming values; literally his only claim to rule was that he was the son of Robert, the previous king. The great irony, of course, was that Joffrey was actually Jaime's bastard son and had no valid claim to the throne, but a shockingly large number of Joffrey's followers continued to blindly obey his crazed orders without question.
Despite his noted incompetence, Joffrey did successfully analyze the key weaknesses of the feudal levy system used to raise and train armies in the Seven Kingdoms, and proposed the radical idea of raising a standing Royal Army to address them, although his proposal that the army also be used to subjugate rebellions even when the army might be drawn from those rebellious regions confirmed his lack of military experience. He was also concerned about reports that Daenerys Targaryen had hatched live dragons in the east, which his grandfather brushed aside as unimportant. Generally, however, Joffrey only rarely made a valid insight as a means for the narrative to underscore that everyone else is overlooking something, i.e. "if someone as stupid as Joffrey realized this, it should have been obvious to everyone else".
