If Tywin drops dead before the Purple Wedding, who gets the Rock?

If Tywin died suddenly before AGOT starts, who would inherit Casterly Rock? Jaimie is out, so would it go to Tyrion or Kevan?

ravenking1771 said:Hey there I saw the recent question about the Casterly Rock inheritance and I wanted to know how firmly did the medieval aristocracy adhere to inheritance I.e. Tyrion is Tywin eldest eligible make child and thus from a legal perspective his heir but Tywin does not consider him and if Tywin died before the events of the novel Tyrion would no doubt be challenged if not passed over by his family, so I wanted know how firmly did these governments respect inheritance rights?

Since I’ve gotten a couple questions about this, I figure I should probably consolidate them into one response rather than repeat myself. It depends on what Tywin set out in his will, and the balance of political power when it comes to both the claimants and whoever might enforce and/or recognize the validity of the will. 

Certainly, Tyrion would have a very strong claim under Westerosi law; he is the oldest eligible male child of the deceased, and he had done nothing that would make him ineligible (like joining the Night’s Watch or the Citadel or the Faith). 

However, whoever Tywin named in the will would also have a claim, and that claim would be buttressed by that person’s own lineage – if it’s Cersei, proximity would no doubt be stressed as well as the will; if it’s Kevan, then he’d be pointing to being the son of Tytos as well as Tywin’s brother as well as the wil. And so on. 

But the balance of power is important: if Tywin dies pre-AGOT, Cersei is going to lobby for her own line (whether for herself or one of her children), and Robert might give in or he might give it to Tyrion out of spite, or he might want to give it to Kevan b/c Kevan fits his mental model of a strong Warden of the West (in the same way that he didn’t want a sickly boy to hold the Wardenship of the East). At the same time, Jon Arryn’s wishes would play a large role in that situation; he’s more of a traditionalist, so he might want it to go to Tyrion because Andal law says so and wills that go against the law lead to civil war and disorder. 

If Tywin dies pre-Purple Wedding, it depends when exactly. If it’s after the Battle of Blackwater, Cersei is Regent and Tyrion has lost his handship, so he’s at a disadvantage. If it’s before the Battle of Blackwater, Tyrion has a significant advantage. 

However, a lot would depend on how the Lannister lords at the Rock or at Harrenhal or at King’s Landing decide to jump: do they take their cues from Kevan as the oldest male Lannister on the spot, and does that mean he gets to play kingmaker or does he go for the Rock himself? Is their misogyny stronger than their ableism or vice versa? Do they fear that Tyrion’s heirs would inherit both the Rock and Winterfell, or that Cersei’s children would inherit both the Rock and the throne and/or Storm’s End? 

Was Randyll acting within the bounds of the law in forcing his legal heir to surrender all property rights ? Theoretically, could Sam have gone to Highgarden to seek intervention from their liege lord? Do you think there was any chance of Mace standing up for Sam against one of his principal bannerman (& most able general) ?

This is what GRRM has said on the matter:

“Well, the short answer is that the laws of inheritance in the Seven Kingdoms are modelled on those in real medieval history… which is to say, they were vague, uncodified, subject to varying interpertations, and often contradictory.

A man’s eldest son was his heir. After that the next eldest son. Then the next, etc. Daughters were not considered while there was a living son, except in Dorne, where females had equal right of inheritance according to age.

After the sons, most would say that the eldest daughter is next in line. But there might be an argument from the dead man’s brothers, say. Does a male sibling or a female child take precedence? Each side has a “claim.”

What if there are no childen, only grandchildren and great grandchildren. Is precedence or proximity the more important principle? Do bastards have any rights? What about bastards who have been legitimized, do they go in at the end after the trueborn kids, or according to birth order? What about widows? And what about the will of the deceased? Can a lord disinherit one son, and name a younger son as heir? Or even a bastard?There are no clear cut answers, either in Westeros or in real medieval history. Things were often decided on a case by case basis. A case might set a precedent for later cases… but as often as not, the precedents conflicted as much as the claims.”

Keep in mind, Randyll Tarly wasn’t proposing to write a will that bypassed Sam in favor of Dickon, or any such legal manuever. He was straight-forwardly threatening to murder Sam if he didn’t comply. 

So yes, potentially Sam could have gone to Highgarden and protested that his father was not only breaking the laws of inheritance but was an attempted kinslayer and murderer on top of that. I doubt that Mace Tyrell would have been particularly interested in championing Sam’s claims, however.
