Except for the wealthy Italian city-states and a few other cities which traced their history back to Roman times, most European towns, it must be remembered, dated only from the later middle ages. At first there was little excuse for their existence except to sell to farmers salt, fish, iron, and a few plows. But with the increase of commerce, which, as we shall see, especially marked the thirteenth, fourteenth, and fifteenth centuries, more merchants traveled through the country, ways of spending money multiplied, and the little agricultural villages learned to look on the town as the place to buy not only luxuries but such tools, clothing, and shoes as could be manufactured more conveniently by skillful town artisans than by clumsy rustics. The towns, moreover, became exchanges where surplus farm products could be marketed, where wine could be bartered for wool, or wheat for flax. And as the towns grew in size, the prosperous citizens proved to be the best customers for foreign luxuries, and foreign trade grew apace. Town, trade, and industry thus worked together: trade stimulated industry, industry assisted trade, and the town profited by both. By the sixteenth century the towns had grown out of their infancy and were maintaining a great measure of political and economic freedom. [Sidenote: Freedom of the Towns.] [Sidenote: Town Charters] Originally many a town had belonged to some nobleman's extensive manor and its inhabitants had been under much the same servile obligations to the lord as were the strictly rural serfs. But with the lapse of time and the growth of the towns, the townsmen or burghers had begun a struggle for freedom from their feudal lords. They did not want to pay servile dues to a baron, but preferred to substitute a fixed annual payment for individual obligations; they besought the right to manage their market; they wished to have cases at law tried in a court of their own rather than in the feudal court over which the nobleman presided; and they demanded the right to pay all taxes in a lump sum for the town, themselves assessing and collecting the share of each citizen. These concessions they eventually had won, and each city had its charter, in which its privileges were enumerated and recognized by the authority of the nobleman, or of the king, to whom the city owed allegiance. In England these charters had been acquired generally by merchant gilds, upon payment of a substantial sum to the nobleman; in France frequently the townsmen had formed associations, called _communes_, and had rebelled successfully against their feudal lords; in Germany the cities had leagued together for mutual protection and for the acquisition of common privileges. Other towns, formerly founded by bishops, abbots, or counts, had received charters at the very outset. [Sidenote: Merchant Gilds]
