What are some alternate history stories that involve superheroes in either comics, novels or films? The only one I can think of is that excellent book by Mark Millar, Superman: Red Son.
To some extent I think all superhero stories are Alt History. They represent a change in society from today's world. The present of a Superman (or Batman) would change many aspects of life - with a Superman the interaction of nations would be different (A Superman could eliminate threats to the US) and the there would be changes in the way crime and the justice system would work.
Oh how that happened is easy. Alan Moore has no idea how the US government works, but thinks he's much smarter than he actually is, so he decided it would be cool to include that as a jab at the Reagan administration. Same reason he had Vietnam annexed by the US and made into a state in the comic.and that somehow this afforded Nixon enough popularity to get the Constitution amended to let him run for additional terms of office.

There's also The Royals. I haven't read it, but I know it's about European royalty having super powers, fighting in a war that's analogous to the world wars.
I agree that almost every superhero story is a kind of alternate history, more so than most fiction.
