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.
France, a regenerated France, turned upon the popes of the Council of Constance, and, remembering how long she had held the papacy within her own borders, asserted at least a qualified independence of the Romans by the "Pragmatic Sanction" which established the Gallican Church.[36]
This semi-defiance of the Pope was encouraged by King Charles, who, in fact, made several shrewd moves to secure the power which his good-fortune, and not his abilities, had won. Among other innovations he established a "standing army," the first permanent body of government troops in Teutonic Europe. By this step he did much to alter the mediæval into the modern world; he did much to establish that supremacy of kings over both nobles and people which continued in France and more or less throughout all Europe for over three centuries to follow.
Another sign of the coming of a new and more vigorous era is to be seen in the beginning of exploration down the Atlantic coast of Africa by the Portuguese, and their discovery and settlement of the Canary Isles. As a first product of their voyages the explorers introduced negro slavery into Europe[37]—a grim hint that the next age with increasing power was to face increasing responsibilities as well.
An even greater change was coming, was already glimmering into light. In that same year of King Charles' Pragmatic Sanction (1438), though yet unknown to warring princes and wrangling churchmen, John Gutenberg, in a little German workshop, had evolved the idea of movable types, that is, of modern printing. From his press sprang the two great modern genii, education and publicity, which have already made tyrannies and slaveries impossible, pragmatic sanctions unnecessary, and which may one day do as much for standing armies.
