Who Inherited House Tyrell'S Lands After The War?

I still get goosebumps thinking about Jaime riding into Highgarden—what a power move. From the TV side of things, after the big conflicts the Tyrell family is basically gone as a ruling dynasty. Jaime captures Highgarden in Season 7, and that conquest hands the Tyrell lands over to Lannister control at least temporarily. So if you ask who ‘inherited’ the Tyrell estates after the fighting shown on screen, the practical answer is that the Lannisters ended up in possession of Highgarden and the Reach until the later chaos of King’s Landing changed the political map again.

On the book side (the slow-moving but gorgeous 'A Song of Ice and Fire'), the Tyrells still have living heirs and their seat at Highgarden hasn’t been transferred away like it was on screen. I often tell newer readers that one of the big differences between the show and the novels is exactly this: the show collapsed, killed, and reassigned houses quickly; the books keep more dynastic continuity. So, short-ish takeaway: show = Lannister takeover of the Tyrell lands; books = still Tyrell-held, pending future volumes.

I tend to keep my fandom notes concise: the fate of the Tyrell lands depends on which canon you follow. In the TV adaptation of 'Game of Thrones', the sequence of events—Margaery’s death, Olenna’s final scene, and Jaime’s capture of Highgarden—leaves the Tyrells politically dead and Highgarden in Lannister hands for the immediate aftermath. The show never explicitly hands the Reach to a new permanent house before the series ends, so it’s effectively Lannister-occupied land that later gets swallowed up by the larger collapse.

In contrast, in the novels by George R. R. Martin, the Tyrell line hasn’t been extinguished in the same way; heirs like Willas and Garlan still exist in the published volumes, meaning Highgarden remains Tyrell territory for now. I always mention this when debating who ‘won’ the Reach—show viewers get a blunt transfer to the Lannisters, while book readers are still waiting on the author to settle the matter.

There’s a bit of a split depending on whether you’re talking about the TV series or the books, and that’s where I usually get into friendly debates with people online. In HBO’s 'Game of Thrones' the Tyrells are essentially erased as a political force: Margaery and Loras die in the events surrounding the Sept, Olenna is killed after Highgarden falls, and Jaime captures Highgarden for the Lannisters in Season 7. Practically speaking, that means the Lannisters took control of Highgarden and the Reach for a time, since Jaime’s conquest put the castle—and its lands—under Lannister occupation. The show never hands the Reach off neatly to a new ruling house before it ends, though, so there’s an ambiguous gap between conquest and the final political settlement.

If you read 'A Song of Ice and Fire' instead, things are very different: the Tyrells aren’t wiped out in the same way. Willas and Garlan Tyrell are still alive in the books (even if Willas is sidelined by injury), so Highgarden and the wider Reach remain Tyrell-controlled in the novels for now. George R. R. Martin hasn’t completed the later wars in the published books, so any full inheritance or redistribution of Tyrell lands after a final ‘war’ is still unresolved in the source material. I’m always telling friends: if you want a clean, final ruling on who inherits the Reach, the show gives you a messy hint (Lannister takeover), the books leave it open, and the real payoff will come when Martin finishes the series and we can see how Great Houses rise and fall in his version.
