How did Joan of Arc help to unify in France?

Joan of Arc played a crucial role in unifying France during the Hundred Years' War by rallying the French troops and inspiring them with her fervent belief in their cause. Her leadership and victories, particularly the lifting of the siege of Orléans in 1429, boosted French morale and galvanized public support for the Dauphin, Charles VII. By promoting the idea of a divinely ordained mission, she helped foster a sense of national identity and purpose among the French people, ultimately contributing to the restoration of Charles VII's authority. Joan's legacy as a national heroine further solidified the unity of France in the face of external threats.
