I have told you the story of the castles and the monasteries, with their heavy stone enclosures—the homes of the knights and the monks, who guarded men’s bodies and their souls. You have seen how a few artisans (butchers and bakers and an occasional candle stick maker) came to live near the castle to tend to the wants of their masters and to find protection in case of danger. Sometimes the feudal lord allowed these people to surround their houses with a stockade. But they were dependent for their living upon the good-will of the mighty Seigneur of the castle. When he went about they knelt before him and kissed his hand. Then came the Crusades and many things changed. The migrations had driven people from the north-east to the west. The Crusades made millions of people travel from the west to the highly civilised regions of the south-east. They discovered that the world was not bounded by the four walls of their little settlement. They came to appreciate better clothes, more comfortable houses, new dishes, products of the mysterious Orient. After their return to their old homes, they insisted that they be supplied with those articles. The peddler with his pack upon his back—the only merchant of the Dark Ages—added these goods to his old merchandise, bought a cart, hired a few ex-crusaders to protect him against the crime wave which followed this great international war, and went forth to do business upon a more modern and larger scale. His career was not an easy one. Every time he entered the domains of another Lord he had to pay tolls and taxes. But the business was profitable all the same and the peddler continued to make his rounds. Soon certain energetic merchants discovered that the goods which they had always imported from afar could be made at home. They turned part of their homes into a work shop. They ceased to be merchants and became manufacturers. They sold their products not only to the lord of the castle and to the abbot in his monastery, but they exported them to nearby towns. The lord and the abbot paid them with products of their farms, eggs and wines, and with honey, which in those early days was used as sugar. But the citizens of distant towns were obliged to pay in cash and the manufacturer and the merchant began to own little pieces of gold, which entirely changed their position in the society of the early Middle Ages.
