History musicals tend not to go down very well (Rex, I and Albert, Thomas and the King, Ben Franklin in Paris, La Révolution Française). Apart from 1776, I can't think of one that has been successful.
Assassins, Gypsy, The King And I, Sunday In The Park With George. I think I've exhausted all the cast recordings on my iPod that reference real people. :)
I do get where you were coming from though, there's a big difference between a musical that happens to be set in the past and a musical about a historical figure. I still get points for Evita though.
