I've always been fascinated by Joan of Arc. If the historical aspects of her story are true, as they're widely accepted to be, she is one of the most interesting people in history. The religious visions aside, how is it possible that a teenage girl talked her way into the French court, won the Dauphin's trust, and proceeded to lead the French army to several victories?
As an aside, what are the theories on her visions?
She is a fascinating woman, the short answer is that we have little conclusive evidence for arguments one way or another (unless you take it as a matter of faith that God was assisting Joan). Was Joan a commander or a figurehead, how did she reach Charles VII and was she acting independently (I think it unlikely that she was an 'agent' but there is circumstantial evidence for a certain court faction attaching themselves to or facilitating her meteoric rise in Charles's court), what were the nature of her voice(s)/visions and what was her 'mission'?
I've discussed aspects of her life and death on the sub, but I'm a bit busy to expand or synthesise on them right now. You should probably begin with a brief overview of the major sources (her trial for heresy and the Nullification trial which occurred after the Hundred Years War ended). This is a somewhat more scattered analysis of Joan's intentions and youth alongside how we can tell Joan believed her own words. Finally, I did a breakdown of Joan's military career (largely in relation to whether she fought or not - short answer no.)
If there is anything you'd like me to expand on then I'm afraid it'll have to wait until the weekend (at least). So possibly post your questions on the main sub and drop me a PM to let me know. Also, read Craig Taylor's introduction, it might answer many of your other questions!
