Direct answer
Because it was an adaptation, not a scene-by-scene copy, and TV needed a smaller, faster-moving version of George R. R. Martin’s huge story. The biggest split came when the show caught up to the unfinished books, so it used some of Martin’s planned endgame ideas but built its own route to them.
Detailed explanation
## It was never meant to copy every page
Game of Thrones began as an HBO adaptation of A Song of Ice and Fire, not a promise to put every chapter on screen exactly as written. David Benioff and D. B. Weiss ran the TV production and made the final script decisions, while George R. R. Martin was a co-executive producer and a major source of advice. Even Season 1, which is famously close to A Game of Thrones, trims, combines, and reshapes things. “Winter Is Coming” streamlines the royal visit to Winterfell, and the show adjusts ages, timing, character details, and how information is delivered.
That is normal adaptation stuff, especially with these books. Martin can spend pages inside Ned Stark’s thoughts or show a political situation through several point-of-view characters. Television has to make that understandable through scenes, performances, and dialogue. The show also leaned into moments that played strongly on screen: big confrontations, visual spectacle, and clear character pairings. Some fans treat any difference as a mistake, but changes existed from the start. The real question is whether a change helped the TV story or caused bigger problems later.
## The books have far more moving parts
The novels are packed with characters and plot branches that would have been hard to keep active in an eight-season TV show. There are more factions in the books, more minor nobles with their own agendas, more journeys through Essos, and much more political detail in Dorne, the Riverlands, the Iron Islands, and the Vale. A novel can introduce a new claimant late in the story and let readers sit with the mystery. A TV series has to consider whether viewers will remember that person, whether there is room for their story, and whether the actor can stay available for years.
That is why the show cut characters such as Lady Stoneheart, Jeyne Poole, Victarion Greyjoy, Quentyn Martell, and Young Griff/Aegon. Removing them did not just erase side plots; it forced the show to hand their story jobs to other people. Tyrion reaches Daenerys much faster because there is no Young Griff and Jon Connington detour. Euron keeps the name and Greyjoy role, but loses much of the book version’s strange occult menace and dragon-binding ambitions. These choices made the show easier to follow, but they also changed the shape of the endgame.
## Sansa and Ramsay show how consolidation worked
Season 5’s most controversial book change is a perfect example of the show combining plots. In “Unbowed, Unbent, Unbroken,” Sansa Stark is sent to Winterfell and married to Ramsay Bolton. In the published books, that is not Sansa’s story. Ramsay marries Jeyne Poole, Sansa’s childhood friend, who is forced to pose as Arya Stark. Meanwhile, book Sansa is alive and politically important in the Vale under the name Alayne Stone, where Littlefinger is planning around her possible marriage to Harry Hardyng.
The show had no Jeyne Poole, and it had reduced the Vale material, so it gave Sansa the northern plot instead. That gave a major actress and a familiar character a central role in the anti-Bolton story. But it also had a cost: Sansa’s TV trauma, her relationship with Littlefinger, and her path back to power are very different from the books. It is not accurate to call this simply “the same event with a renamed bride.” The bride swap changes who has agency, what the Boltons are trying to prove, and where Sansa is during a major stretch of the story.
## The show caught up to unfinished books
This was the biggest practical reason the later seasons diverged. A Dance with Dragons, the fifth published main novel, came out in 2011, the same year Game of Thrones premiered. The next books, The Winds of Winter and A Dream of Spring, were not published while the series ran. By around Seasons 5 and 6, the show had adapted, skipped, merged, or passed much of the main material that existed in finished form.
That does not mean the writers had literally no book material after Season 5. A Feast for Crows and A Dance with Dragons still contained plenty of unused pieces, especially in Dorne, the Iron Islands, the Vale, and the northern story. But those pieces were tied to characters the show had already removed or heavily changed. Once Young Griff is gone, for example, a lot of Tyrion, Varys, Jon Connington, and Daenerys-related book politics cannot be adapted the same way. The series had to stop asking, “How do we film this chapter?” and start asking, “How do we finish this version of the story?”
## Martin shared some destinations, not a finished map
Martin did tell Benioff and Weiss some important future story information. The clearest confirmed example is Hodor. After Season 6’s “The Door,” Martin said the core “hold the door” revelation came from him: Bran’s time-traveling interference helps create Hodor’s condition. That is a shared major idea, even if the eventual book scene may use different details, timing, or characters.
Stannis burning Shireen in “The Dance of Dragons” is another case often discussed. Martin has indicated that this was among the big pieces of information he gave the showrunners. Still, the published books have not reached that point. Book Stannis is campaigning in the North, while Shireen remains at the Wall, so fans do not know the exact circumstances, who pushes for it, or how it connects to Stannis’s fate.
The key distinction is broad endpoint versus exact route. Martin gave them some destinations and revelations, but not two completed novels spelling out every motive and consequence. A TV version can arrive at a similar shocking event through a completely different chain of choices.
## Why the ending feels especially different
The final seasons had fewer episodes and a lot of story left to resolve: the war against the dead, Daenerys’s invasion, Cersei’s rule, the northern leadership question, and the future of Westeros. That encouraged a more streamlined, direct path. The TV-only Night King is a good example. The books have the Others and a historical figure called the Night’s King, but no present-day White Walker leader called the Night King. Giving the enemy one visible leader made the show’s supernatural war much easier to stage and conclude.
Other late events remain uncertain as book predictions. Cersei destroying the Great Sept of Baelor in “The Winds of Winter” has no published novel equivalent. Bran becoming king, Jon killing Daenerys, and Arya sailing west in “The Iron Throne” are canon for HBO’s show, but Martin has said the book ending will have important differences. Some may echo his plans; others may be TV inventions or heavily transformed versions of them. Nobody can honestly claim the show followed Martin’s ending exactly until the final novels exist.
