Just because this happened exclusively in England, it does not mean that this could not have occurred elsewhere in Europe. Social/political conditions in England were no different than anywhere else. Its a mere coincidence that only England experienced this.
But when you have such series in other countries, it's not a coincidence.
Now of course, the thread is yours. It is up to you to define it. Credibility however, is open to debate.
My point of view, already expressed in quite many recurring threads of this forum, is that french leadership was so incompetent during the HYW that if the Plantagenet/Lancaster did not win, it's that they just could not win on the field they chose.
Even if Charles VII died somewhere between 1422 and 1429, with the duke Orleans prisoner and childless, the Armagnac party would rally around around the Valois Anjou, who were the key support of Charles VII and who were next in line of succession after the Valois Orleans.
If Joan of war ever was to a certain extent set-up by a behind the scene political godfather, guess who was this political godfather. It was the house of Valois Anjou. Joan of Arc came from a region that was loyal to the house of Valois Anjou and sent to Bourges by local nobles that were clients of the Valois Anjou (and especially Yolande of Aragon, who happened to be the mastermind of the party and the mother in law of Charles VII).
One can't force someone else to want something it rejects without being able to crush any opposition.
The french would opt for any alternative solution rather than submit to the one who established himself as their arch-enemy : the king of England.
Same as for the portuguese who set up bastards or collateral branches as national kings. Same for sicilians-napolitans. Same for those who invented succession rules that would prevent the crown going to someone outside the male line of the dynasty. Same for the Dutch who rallied around a new dynasty when their legitimate dynasty began to force on them policies they rejected and considered alien. Same for the poles who organized the wedding of Hedwig of Anjou with the Lithuanian Jagellon in order to avoid being captured by the Habsburgs.
I more or less said all I had to say.
Good luck with your thread.
