Dunstonbury could have been at the mouth of the river, although I’ve suggested somewhere else.
The problem with the Hightower theory, to me, is that the Hightowers weren’t always part of the Gardener polity, and the Mander was incredibly central to House Gardener’s rise.
I don’t know if I’d go as far as “it didn’t seem that popular outside Europe and Japan” – once you add in Russia, India, and China to your list of historical feudalisms, you’ve got a big chunk of the globe right there – although I will agree that it’s not a universal experience either (since you don’t see pretty much all of Africa or any of the Americas on that list, although you can make some quibbles about certain periods of colonialism).
That being said, treating feudalism (or arguably any social order) as natural or inevitable is a major error in thinking. I blame Hegel and Marx for that one.
I don’t think it’s an accident that there is a conflict between these two customs: guest right exists somewhat to create a systemic dis-incentive to kill hostages. And that’s not a bad thing, because the point of hostage-taking (and especially true with hostage-exchanges) is to create an alternative to wiping out your enemies root and branch, similar to how the custom of ransoms is there to encourage people to take defeated nobles prisoner instead of murdering them for the rings on their fingers.
However, there are cases where you need to execute a hostage. My guess is that the cultural circle is squared through giving hostages guest gifts:
“The Freys came here by sea. They have no horses with them, so I shall present each of them with a palfrey as a guest gift. Do hosts still give guest gifts in the south?“
“Some do, my lord. On the day their guest departs.”
“Perhaps you understand, then.“ (ADWD)
Thus, the hostage is no longer a guest and can be executed without violating the taboo.
Hey folks! Now that Politics of Dorne (and with it, the entire Politics of the Seven Kingdom series) is done, it’s back to ASOS (which I know will make some of you very happy indeed). Also, I should have an exciting book-related announcement in a day or two. In the mean-time, we’ve got Tumblrs: ASOIAF Karma for the Pie Man? Political maps of Westeros. Dornish support for the Blackfyres. Dorne’s…
I think a couple different things would be necessary for a Riverlander King to become dominant:
economic/political/military development so that the Riverlands can bring its full potential to bear on its various challenges. If the Riverlands could raise 40-45,000 men as their population indicates they ought to be able to raise, or if their borders were better guarded by stronger castles, then they’d stand a much better chance against the Westermen, the Ironborn, the Valemen, the Reachermen, and the Stormlanders.
a stroke of geostrategic luck. Given the multi-front nature of the great game, it’s much easier for the Riverlands to do well if the Vale is fighting the North and/or the Westermen are fighting the Ironbron and/or the Stormlands/Dorne/Reach are all fighting eachother.
good leadership who can combine diplomatic and military talent to achieve one doable objective at a time. For example, if the Riverlands could work out deals with other kingdoms that would allow it to redistribute resources from one or two fronts, that would allow them to concentrate their resources in another direction. LIkewise, while absorbing the Crownlands is a reasonable goal, making a frontal assault on the Bloody Gate or picking simultaneous fights with all of its neighbors at once.
“So young,” said Wyman Manderly. “Though mayhaps this was a blessing. Had he lived, he would have grown up to be a Frey.” Ser Hosteen slammed his foot into the tabletop, knocking it off its trestles, back into Lord Wyman’s swollen belly. Cups and platters flew, sausages scattered everywhere, and a dozen Manderly men came cursing to their feet. Some grabbed up knives, platters, flagons, anything that might serve as a weapon.
to act as a check on the Reach and the Stormlands – neither could “win” by permanently absorbing one of their neighbors because every time they focused their efforts in that direction, Dorne would hit them with raids that would either force them to pull back to keep what they had or weaken them to the point where they would be become too weak to hold on to what they’d grabbed.
to act as a scavenger in times of weakness – hence invading the Reach during the reign of Garth X or attacking the Stormlands repeatedly when the Stormlands are on their way down – although this isn’t unique to Dorne.
