Henry V and Charles VI died within two months of each other in 1422, and Henry V's infant son (Charles VI's grandson) Henry VI became King of France. He was the only English king who was de facto King of France, rather than using the style as a mere title of pretense. By 1429 Charles VII, with the support of Joan of Arc, had been crowned at Reims and begun to push the English out of northern France. In 1435, an end to the French civil war between Burgundians and Armagnacs allowed Charles to return to Paris the following year, and by 1453 the English had been driven out of their last strongholds in Normandy and Guyenne. The only French territory left to the English was Calais which they held until 1558 and the Channel Islands.
