War of the Roses - causes

[Ibrahim]

well, one must also remember, that with all the rivalries and personal intrigues between somerset and york, the role (or lack of) of Henry VI. the fact that he showed weakness and lack of restraining the two houses of york and somerset, as well as Margeret, was the cause of the war dragging on beyond St.Albans, which in itself was quite an interesting battle. whoever knew Somerset would die under a wierdly named tavern?

so basically, the war had multiple causes:

1-loss of the hundred years war.
2-feud developing between York and somerset.
3-Margeret interveneing and scheming with Somerset for her benifit.
4-finally, weakness on the part of the king.

no one cause was alone to lead to this shameful waste, but rather all added feul to a fire, so to speak.
