I was curious to see where the inspirations for Game of thrones came from; I studied the war of the roses in school like, two decades ago or something, so I'm aware of names like 'Plantagenets' and 'York' and such, but can't recall for the life of me much else.

When watching Game of thrones it got easy to forget who was who, given the gigantic cast of characters (mostly secondary obviously), and I'll probably have a difficult time here too, but I'd still love to get a refresher.
