GROWTH OF THE CITIES.—The same need of defense that led to the building of towers and castles in the country drove men within the walls of towns. Industry and trade developed intelligence, and produced wealth. But burghers under the feudal rule were obliged to pay heavy tolls and taxes. For example, for protection on a journey through any patch of territory, they were required to make a payment. Besides the regular exactions, they were exposed to most vexatious depredations of a lawless kind. As they advanced in thrift and wealth, communities that were made up largely of artisans and tradesmen armed themselves for their own defense. From self-defense they proceeded farther, and extorted exemptions and privileges from the suzerain, the effect of which was to give them a high though limited degree of self-government.

ORIGIN OF MUNICIPAL FREEDOM.—It has been supposed that municipal government in the Middle Ages was a revival of old Roman rights and customs, and thus an heirloom from antiquity. The cities—those on the Rhine and in Gaul, for example—were of Roman origin. But the view of scholars at present is, that municipal liberty, such as existed in the Middle Ages, was a native product of the Germanic peoples. The cities were incorporated into the feudal system. They were subject to a lay lord or to a bishop. In Italy, however, they struggled after a more complete republican system.

CITIES AND SUZERAINS.—In the conflicts which were waged by the cities, they were sometimes helped by the suzerain against the king, and sometimes by the king against the nearer suzerain. In England the cities were apt to ally themselves with the nobility against the king: in Germany and France the reverse was the fact. But in Germany the cities which came into an immediate relation to the sovereign were less closely dependent on him than were the cities in France on the French king.

TWO CLASSES OF CITIES.—Not only did the cities wrest from the lords a large measure of freedom: it was often freely conceded to them. Nobles, in order to bring together artisans, and to build up a community in their own neighborhood, granted extraordinary privileges. Charters were given to cities by the king. Communities thus formed differed from the other class of cities in not having the same privilege of administering justice within their limits.

GERMAN CITIES.—The cities in Germany increased in number on the fall of the Hohenstaufen family. They made the inclosure of their walls a place of refuge, as the nobles did the vicinity of their castles. They eventually gained admittance to the Diets of the empire. They formed leagues among themselves, which, however, did not become political bodies, any more than the Italian leagues.

THE ROMAN LAW.—The revised study of the Roman law brought in a code at variance with feudal principles. The middle class, that was growing up in the great commercial cities, availed themselves, as far as they could, of its principles in regard to the inheritance of property. The legists helped in a thousand ways to emancipate them from the yoke of feudal traditions.

MUNICIPAL GOVERNMENT.—The cities themselves often had vassals, and became suzerains. Government rested in the hands of the magistrates. They were chosen by the general assembly of the inhabitants, who were called together by the tolling of the bell. The magistrates governed without much restraint until another election, unless there were popular outbreaks, "which were at this time," as Guizot remarks, "the great guarantee for good government." Where the courage and spirit of burghers were displayed was in the maintenance of their own privileges, or purely in self-defense. In all other relations they showed the utmost humility; and in the twelfth century, when their emancipation is commonly dated, they did not pretend to interfere in the government of the country.

TRAVELERS AND TRADE.—The East, especially India, was conceived of as a region of boundless riches; but commerce with the East was hindered by a thousand difficulties and dangers. Curiosity led travelers to penetrate into the countries of Asia. Among them the Polo family of Venice, of whom Marco was the most famous, were specially distinguished. Marco Polo lived in China, with his father and his uncle, twenty-six years. After his return, and during his captivity at Genoa, he wrote the celebrated accounts of his travels. He died about 1324. Sir John Mandeville also wrote of his travels, but most of his descriptions were taken from the work of Friar Odoric, of Pordenone, who had visited the Far East. Merchants did not venture so far as did bold explorers of a scientific turn. Commerce in the Middle Ages was mainly in two districts,—the borders of the North Sea and of the Baltic, and the countries upon the Mediterranean. Trade in the cities on the African coast, in the tenth and eleventh centuries, was flourishing; and the Arabs of Spain were industrious and rich. Arles, Marseilles, Nice, Genoa, Florence, Amalfi, Venice, vied with one another in traffic with the East. Intermediate between Venice and Genoa, and the north of Europe, were flourishing marts, among which Strasburg and other cities on the Rhine—Augsburg, Ulm, Ratisbon, Vienna, and Nuremberg—were among the most prominent. Through these cities flowed the currents of trade from the North to the South, and from the South to the North.

THE HANSEATIC LEAGUE.—To protect themselves against the feudal lords and against pirates, the cities of Northern Germany formed (about 1241) the Hanseatic League, which, at the height of its power, included eighty-five cities, besides many other cities more or less closely affiliated with it. This league was dominant, as regards trade and commerce, in the north of Europe, and united under it the cities on the Baltic and the Rhine, as well as the large cities of Flanders. Its merchants had control of the fisheries, the mines, the agriculture, and manufactures of Germany. Lübeck, Cologne, Brunswick, and Dantzic were its principal places. Lübeck was its chief center. In all the principal towns on the highways of commerce, the flag of the Hansa floated over its counting-houses. Wherever the influence of the league reached, its regulations were in force. It almost succeeded in monopolizing the trade of Europe north of Italy.

FLANDERS: ENGLAND: FRANCE.—The numerous cities of Flanders—of which Ghent, Ypres, and Bruges were best known—became hives of industry and of thrift. Ghent, at the end of the thirteenth century, surpassed Paris in riches and power. In the latter part of the fourteenth century, the number of its fighting men was estimated at eighty thousand. The development of Holland was more slow. Amsterdam was constituted a town in the middle of the thirteenth century. England began to exchange products with Spain. It sent its sheep, and brought back the horses of the Arabians. The cities of France—Rouen, Orleans, Rheims, Lyons, Marseilles, etc.—were alive with manufactures and trade. In the twelfth century the yearly fairs at Troyes, St. Denis, and Beaucaire were famous all over Europe.
