On Louis (VIII): "In January 1226, a papal legate excommunicated Count Raymond VII, although he had made his submission and sought absolution at Bourges in the preceding year. The Church confirmed the possession of Raymond's lands to the king, with the right to hold them and to bequeath them to his successors. Amaury de Montfort, for his part, surrendered all title to his fathers conquests, and his uncle, Gui de Montfort, confirmed the cession.
Err...No. It's the reverse situation. FIRST Amaury gives the titles to the king, THEN the curch validate it. Of course, Amaury gives titles void of sense as he lost almost everything.
King Louis took the cross. He received from teh Chruch the normal crusader's indulgences and priviliges for himself and his kingdom...and as early as March 1226 submissions began to come in. They increased with the siege of Avignon and its fall on 9 September, despite the defection of some of the great vassals, who left the army on the completion of their normal forty days' service.
What about the men that stand in service, but tried to slow the king, to avoid him annexing lands, as Tibault de Champagne?
The crusade became a mere military promenade, and the king was able to press on with the organization of royal government in the conquered lands. He retained the administrative system set up by Simon de Montfort, and established a firm alliance with the local clergy. He died on his homeward journey north, at Montpensier, on 8 November 1226.
Military promenade? Well, somwhat it's true. But it's interrupted by the siege of Avinhon that wasn't particularly short and pleasant as the king had trouble to be obeyed of his own men and as he was sickened here.
The city standing 3 months against the king, critically a city serving as the key to enter in Lengadoc, could be considered as a military promenade itself. In fact, it allowed to delaying his expedition long enough to have a pale mirror of what his army was while the men that were still within weren't particularly agreeing with the goals of the king.
But yes, you have surrender of cities (that probably didin't wanted to loose the autonomy they had, as Avinhon did). But the military power of these cities are not really the main problem for Louis, as the campaigns of Simon showed.
Even that, tough, was void of meaning as Louis couldn't attack in the facts : not army big enough, reluctant vassals...He just left the idea to attack this year, and died soon after.
So, what Louis wanted to do : annex the Lengadoc, and especially the county of Tolosa? Fail.
The Capetian Kings of France by Robert Fawtier (translated by Lionel Butler and R J Adam).
Well, since 1942, our vision of the crusade evolved a bit. The book is somewhat obsolete today (even if many of the work of Fawtier is still interesting, critically in his critics of sources) and when it was published in 1942, its goal was to say "hey, France is maybe defeated, but it happened in the past and we're still there". I'm not sure about using it.
Could I suggest you "France in the Middles-Ages 987-1460" of Georges Duby? It's translated in english, and i suppose that you wont have many troubles to find it.
"As the ones his father and his grand father led in Maconnais, the expedition in the south was easy. Nobles of the Narbonensis pledged their alliegance while the king marched in the imperial lands with his sword of justice raised.
But an unexpected obstacle prevented him to continue.
Beyond the river, the urban communauties grew. Bartering their support to the count of Tolosa they gained new powers. Their italian-like policy made them little hard to submit states.
[Details about the siege, to resume, they tought it would be easy to just enter in the city. They were wrong. Louis was persuaded that it was because of the heresy (that of course didn't made any communauty worth of mention here) and besieged it. Hard sun, dysentery-bearing swamps. And the fact the king prevented his men to plunder the city, forbidding them to get wealth this way, just made his army unwilling to continue : what was the point if only the king would benefit of it?]
"If we trust Guillaume of Puylaurens, the previous king always tought that his fragile son would die in the sunny lands"
[It's proposed as an explanation of why Philippe didn't want his son to be part of the souther expedition of 1219, that failed too]
The expedition of Louis didn't give to the crown the lands he wanted. What gave Louis IX a part of these said lands was the political diplomacy : the Count took back his desmene (at the exception of Mediterranean lands, that were in the hands of Trencavel before the crusade anyway). In fact, the lands Raimond lost that was in his possession was the south of Albi viscounty that he took after Raimond Roger and Simon deaths. His core land was totally recognized as his own, as long he fought the heresy.
That's still success by the "let's establish French (as distinct from Occitan) rule" faction - and failure by the Occitans to keep them out. And even more so, success by the monarchy (the kings) - even if it worked as expected, it was still strengthening the monarchy and the dynasty at the expense of the previous nobles.
Again, i wait you show me where the occitan lords were replaced by french ones.
Because, you know, it wasn't. The policy of Louis IX, to pardon massivly and to integrate the occitan nobility as Oliviers de termes at the place of french ones was particularly interesting for this and you could see the results during Philippe le Bel reign by exemple.
In fact, the only worth of mention exemple was the replacement of Trencavel by the king of France. And he acted like an occitan lords as long it regarded his southern desmene. Not talking that ALphonse de Poitiers took back in co-suzerainty (another occitan policy) some lands in Provence that his father-in-law lost.
Someone should. And while Philip preferred not to, Louis seems to have been much more interested.
Because he was nuts? And that his expeditions, except the last ones
Where he is getting people submitting to him? That doesn't count?
Not really in the way you would want. Have you an idea on how much cities submitted during the crusade? Hell, all of them probably submitted themselves at least once or twice. But when the expedition goes in another place, you had "well, in fact we don't see the interest of submitting anymore".
Whether or not it would be guessed isn't the point, the point is that it did work out that way. Louis accomplished what he intended (secure Capet authority, both as in the monarchy and as in the family) - and more (the unexpected inheritance) - here.
Louis didn't accomplished ANYTHING. He died before Isabeau had the idea to marry Alphonse to Joanna of Tolosa. Result of his expedition : nuts.
So, yeah, maybe matrimonial policy isn't as galmour that sucessful military expedition by a chevalresque king, but it worked when the king failed. Simple as that.
If Raymond had a son, and that son inherited all the lands that had been up for question in this whole mess, and Louis and his heirs got nothing for their pains, I would call that a failure.
Again, you're mixing two events. I don't know how to say you : the crusade was officialy finished in 1226 during the treaty of Meaux.
Outcome : the french king gained a domain that was 1/3 of what he claimed, the count of Tolosa remained independent and strong, the occitan cities gained more liberties than ever, and some nobles (as Provença, Fois, Comminges) became more independent. With church gained or reinforcing lands in the south.
So, at the treaty of Meaux, what about the objectives?
1)Catharism, still there and prosperous, thanks to ask.
2)Overthrowing occitan lords, and replacing them with french ones. With the exception of Louis IX becoming count of Carcassona and Nimes and r
elying on occitan nobility to secure it, it was a big fail.
You're free to say "oh but the crusade lasted as long the count of Tolosa wasn't died" or anything else as it's your right to propose such an interpretation.
But for everyone else, crusade ended in 1229. What happen next his consequences and...i don't want to be rude just i don't have the right words here...history is about the facts and their consequences, and the consequences of the consequences. The acquisition of Upper Languedoc is not directly issued from Crusade, as the Western Schism wasn't. It's just consequences, unexpected and being sort of surprising.
To say it in AH-pigdin : "WI - Alphonse de Poitiers don't have a son"
"What if he died without an heir? The french king would have inherited his desmenes, securing his positions in the south against Plantagenets.
And what about putting the Pope in Avignon instead of Rome? It could have led later to a schism between Avignon and Rome papacy

. it's a bit unlikely but it would be fun"
Answer "ASB!", "Unlikely"...etc.
