I could be mistaken, but I think he was asking if, within the realm of magickal history, there are fights as to what is true.
I, however, don't happen to know the answer to such question, so sorry on that front, DemeterF.
Ofcourse, now that I look at it, I see another interpretation that perhaps he's asking if there was ever a historical war that was fought over magick.
I'm seriously not trying to be rude...I just think the previous posters may have misinterpreted your post and when you answered >.< after the first one, you seemed to agree (although, I will admit my knowledge of text based facial expressions isn't great).
I hope I helped clarify things and did not insult you.
