The medieval guilds were capable of maintaining their independence; and, later on, especially in the fourteenth century, when, in consequence of several causes which shall presently be indicated, the old municipal life underwent a deep modification, the younger crafts proved strong enough to conquer their due share in the management of the city affairs. The masses, organized in "minor" arts, rose to wrest the power out of the hands of a growing oligarchy, and mostly succeeded in this task, opening again a new era of prosperity. True, that in some cities the uprising was crushed in blood, and mass decapitations of workers followed, as was the case in Paris in 1306, and in Cologne in 1371. In such cases the city's liberties rapidly fell into decay, and the city was gradually subdued by the central authority. But the majority of the towns had preserved enough of vitality to come out of the turmoil with a new life and vigour.(14) A new period of rejuvenescence was their reward. New life was infused, and it found its expression in splendid architectural monuments, in a new period of prosperity, in a sudden progress of technics and invention, and in a new intellectual movement leading to the Renaissance and to the Reformation. The life of a mediaeval city was a succession of hard battles to conquer liberty and to maintain it. True, that a strong and tenacious race of burghers had developed during those fierce contests; true, that love and worship of the mother city had been bred by these struggles, and that the grand things achieved by the mediaeval communes were a direct outcome of that love. But the sacrifices which the communes had to sustain in the battle for freedom were, nevertheless, cruel, and left deep traces of division on their inner life as well. Very few cities had succeeded, under a concurrence of favourable circumstances, in obtaining liberty at one stroke, and these few mostly lost it equally easily; while the great number had to fight fifty or a hundred years in succession, often more, before their rights to free life had been recognized, and another hundred years to found their liberty on a firm basis--the twelfth century charters thus being but one of the stepping-stones to freedom.(15) In reality, the mediaeval city was a fortified oasis amidst a country plunged into feudal submission, and it had to make room for itself by the force of its arms. In consequence of the causes briefly alluded to in the preceding chapter, each village community had gradually fallen under the yoke of some lay or clerical lord. His house had grown to be a castle, and his brothers-in-arms were now the scum of adventurers, always ready to plunder the peasants. In addition to three days a week which the peasants had to work for the lord, they had also to bear all sorts of exactions for the right to sow and to crop, to be gay or sad, to live, to marry, or to die. And, worst of all, they were continually plundered by the armed robbers of some
