Jedi: Gandhi or Joan of Arc
Sith: Saddam Hussein
shes a myth and nothing more, country girl that was doing what nobility told her, a puppet with no free will of of her own in this process, she was used and discarded - good icon of mercy of H. Mary for simple religious folk of those times. but even if we gonna project any importance to her then she was engaged in slaughtering of englishmen, not exactly jedi like.
as I said before, any ruler/known historical person is a Sith whenether by open actions or conspiracies.
