...because my colleagues have been discussing The Tudors...
How would UK history (and indeed world history) have worked out differently if Henry VIII's first wife had given birth to a son?
I mean, presumably, it would have done, but I'm not enough of a historian to speculate on exactly how.
There must be some good speculative fic about it - it's the sort of thing Connie Willis would do, I'm sure, but doesn't seem to have. If anybody can point me in the direction of something - either published or online - I'd be really grateful.
