Another interesting performance of the Emperor Sigismund was that, being deep in debt, he sold his "electorate" of Brandenburg to a friend, a Hohenzollern, and thus established as one of the four chief families of the empire those Hohenzollerns who rose to be kings of Prussia and have in our own day supplanted the Hapsburgs as emperors of Germany.[30] Also worth noting of Sigismund is the fact that during the sitting of his Council of Constance he made a tour of Europe to persuade all the princes and various potentates to join it. When he reached England he was met by a band of Englishmen who waded into the sea to demand whether by his imperial visit he meant to assert any supremacy over England. Sigismund assured them he did not, and was allowed to land. We may look to this English parade of independence as our last reminder of the old mediaeval conception of the Emperor as being at least in theory the overlord of the whole of Europe. LATTER HALF OF THE HUNDRED YEARS' WAR By this time England had in fact recovered from her period of temporary disorder and depression. King Richard II, the feeble son of the Black Prince, had been deposed in 1399,[31] and a new and vigorous line of rulers, the Lancastrians, reached their culmination in Henry V (1415-1422). Henry revived the French quarrel, and paralleled Crecy and Poitiers with a similar victory at Agincourt.[32] The French King was a madman, and, aided by a civil war among the French nobility, Henry soon had his neighbor's kingdom seemingly helpless at his feet. By the treaty of Troyes he was declared the heir to the French throne, married the mad King's daughter, and dwelt in Paris as regent of the kingdom.[33] The Norman conquest of England seemed balanced by a similar English conquest of France. But the chances of fate are many. Both Henry and his insane father-in-law died in the same year, and while Henry left only a tiny babe to succeed to his claims, the French King left a full-grown though rather worthless son. This young man, Charles VII, continued to deny the English authority, from a safe distance in Southern France. He made, however, no effort to assert himself or retrieve his fortunes; and the English captains in the name of their baby King took possession of one fortress after another, till, in 1429, Orleans was the only French city of rank still barring their way from Charles and the far south.[34] Then came the sudden, wonderful arousing of the French under their peasant heroine, Jeanne d'Arc, and her tragic capture and execution.[35] At last even the French peasantry were roused; and the French nobles forgot their private quarrels and turned a united front against the invaders. The leaderless English lost battle after battle, until of all France they retained only Edward III's first conquest, the city of Calais.
