In 1337 AD the 100 years war' between the French and English kingdoms erupted over territory disputes, ending in 1453 AD. King Edward III of England invaded France claiming he was the rightful ruler. His son, the Prince of Wales accompanied him, aiding his forces when possible. There were four main battles, Plessy, Crecy, Agincourt and Sluys. The English defeated the French legions in all these confrontations, expanding British land while gaining much wealth and authority. The French Barons and their regiments were effectively crushed and there was no form of powerful resistance remaining.
However, Joan of Arc, a young girl at the age of 15, would lead the very last French troops against the opposition. She was special because apparently God spoke to her, giving divine guidance, support and words of wisdom. Joan used this to invoke morale, courage, strength, confidence and hope into the French soldiers, rallying them and pressing an attack. The conflict was significant and changed European society. After numerous key victories, the French contigents were able to re-gain control of their original provinces and besiege others successfully, removing British rule from mainland Europe altogether.
She was finally captured, and convicted of Heresy by an Inquisitor soon after. Found guilty at trial for being a "witch", Joan was excommunicated by the Pope and burnt at the stake mercilessly in 1431 AD. Interestingly, in 1456 AD she was declared innocent during an appeal. In 1920 the Catholic Church recognised her as a Saint and important historical figure for Christianity.
