Joan of Arc supported Charles VII, the French claimant whose coronation she helped make possible at Reims.
Charles was the son of King Charles VI, whose recurring mental illness created a succession crisis during the Hundred Years' War. The Treaty of Troyes had recognized the English king Henry V and his heirs as successors to the French throne, while Charles was treated as illegitimate by his enemies.
Joan's arrival at Charles's court in 1429 strengthened his political position. After French victories, especially the relief of Orléans, Charles traveled to Reims and was crowned there on 17 July 1429. Joan stood near him during the ceremony, carrying her standard.
Charles VII later authorized the 1456 retrial that overturned Joan's condemnation. He is sometimes confused with his father, Charles VI, who was the king during the earlier treaty crisis.
