why was so important for the king of france to be crowned, re joan of arc?

It was the belief at the time that Joan of Arc was blessed sa pamamagitan ng God and visited sa pamamagitan ng angels, and religion was extremely important back then, especially to Royals, as they believed it was their God ibingiay right to rule. So, to be crowed sa pamamagitan ng a girl who was blessed sa pamamagitan ng God and had the support of most of France would have boosted the King's authority.
