The area of trade, though, according to modern ideas, restricted, was fairly extensive. It included all the countries in modern Europe and the adjacent seas. The sea-trade was carried on in the Mediterranean and Black Seas, in the Baltic and North Seas, and down the western coasts of France and Spain. The North Sea was the great fishing ground, and large quantities of dried fish, necessary for the due keeping of Lent, were despatched in coasting vessels, and by the overland routes to the southern countries of Europe. Furs, skins, and corn came from Russia and the northern countries. Spain, some parts of Germany, and above all England, were the wool-exporting countries. The eastern counties of England, many towns in Germany and France, and especially the Low Countries, were the centres of the woollen manufactures. The north of France was the great flax-growing country. In Italy, at Barcelona in Spain, and at Lyons in France, silk was produced and manufactured. The spices and dried fruits of the East, and its silks and costly brocades and feathers, came from the Levant to Venice, and were carried north through the great passes which pierce the range of the Alps. Civic statesmen did their best, by mutual bargains and the establishment of factories, to protect and extend trading facilities for their townsmen. The German merchant had his magnificent _Fondaco dei Tedeschi_ in Venice, his factories of the Hanseatic League in London, Bruges, Bergen, and even in far-off Novgorod; and Englishmen had also their factories in foreign parts, within which they could buy and sell in peace. The perils of the German merchant, in spite of all civic leagues, were at home rather than abroad. His country swarmed with Free Nobles, each of whom looked upon himself as a sovereign power, with full right to do as he pleased within his own dominions, whether these were an extensive principality or a few hundred acres surrounding his castle. He could impose what tolls or customs dues he pleased on the merchants whose heavily-laden waggons entered his territories. He had customary rights which made bad roads and the lack of bridges advantages to the lord of the soil. If an axle or wheel broke, if a waggon upset in crossing a dangerous ford, the bales thrown on the path or stranded on the banks of the stream could be claimed by the proprietor of the land. Worse than all were the perils from the robber-knights—men who insisted on their right to make private war even when that took the form of highway robbery, and who largely subsisted on the gains which came, as they said, from making their “horses bite off the purses of travellers.”
