Mainly because, contrary to the feudal system that was forced to have some consideration for the king (to resume, because it was the legitimisation of the power of great nobles, overhtrowing him would have gave pretext to their own vassals to do the same with them), the islamic institutions didn't were forced to respect the amir/caliphe as their "lieges"'s land weren't given by him : it was their own, they gained themselves.What makes you think that?
Maybe you think i'm opsimistic, but the concept of kingdom as the private poperty of the sovereign disappeared with the Post-Carolingian Reformation.I think you are looking at things a bit optimistically here. This was a struggle for the throne of France which different parties viewed as property. That family members fought doesn't seem dispositive; this happened in Al-Andalus, or in the Ottoman Empire, too.
Let's say that between Hugues Capet and Philippe Le Bel, you had still this idea present but concurenceed. But after Philippe, the main concept was more "the king is the guardian of a state, he's not its owner but the garant of the respect of its liberties".
You're probably confusing the TITLE which was an inheritence, and the KINGDOM which was a proper thing.
In Al-Andalus, at the contrary, the lands were considered as propety and the titles as a moral persona.
Sort of yes. But it's the formation of feudality in England, and it couldn't be considered as a normal feudal situation.So, like in Scotland, where there was tension between the Norman lords and the old elite?
Did i say that? No. What i said is western feudalism was more stable than the tribal structures of Arabo-Islamic world.I mean, John the Fearless in Burgundy was killed by his son in law. This isn't a warm and fuzzy society either.
By the way...Yes this murder (not wanted by Charles VII, but the Armagnac party forced him to accept this) was mainly political, again in the struggle between Armagnac and Bourguignon parties. You can read the "Diairy of a Parisian bourgeois", it's really interesting about it.
I'm not sure why this is a downside here, even if we grant that it's true. (And the reign of the French monarchs during the 14th century makes one skeptical)..
Well, I am sure of it. Can you give me ONE occasion between 1000 and 1500 where the king was seriously threatened to be overthrow by someone that didn't have a serious pretext? Like, i don't know...A familial tie? I'll prevent you to loose your time : no.
It really looks to me like both Christians and Muslims united and divided. Almovarids, Umayyads, Almohads; Sanchez the Fat, and then his heirs.
Then i would suggest you to study more closely who's fighting during the steps of Reconquista.
You have almost all the times muslims under the authority of the amir or caliphe that join the Christian, when you have almost never Christian joining the islamic army against Christians. The only exemple of this that came in my memory is the sack of Santiago de Compostella, and even there, Christian tried to betray Almanzor to help the Leonese.
