The Commercial Revolution

Changes in business procedures, combined with the growth in trade, led to a transformation of the European economy often called the commercial revolution by historians, who see it as the beginning of the modern capitalist economy. In using this label, historians point not only to increases in the sheer volume of trade and in the complexity and sophistication of business procedures, but also to the development of a new “capitalist spirit” in which making a profit is regarded as a good thing in itself, regardless of the uses to which that profit is put. (See “Individuals in Society: Francesco Datini.”) Because capitalism in the Middle Ages primarily involved trade rather than production, it is referred to as mercantile capitalism.

Part of this capitalist spirit was a new attitude toward time. Country people needed only approximate times — dawn, noon, sunset — for their work. Monasteries needed more precise times to call monks together for the recitation of the Divine Office. In the early Middle Ages monks used a combination of hourglasses, sundials, and water-clocks to determine the time, and then rang bells by hand. In about 1280 new types of mechanical mechanisms seem to have been devised in which weights replaced falling water and bells were rung automatically. Records begin to use the word clock (from the Latin word for bell) for these machines, which sometimes indicated the movement of astronomical bodies as well as the hours. The merchants who ran city councils quickly saw clocks as useful, as these devices allowed the opening and closing of markets and shops to be set to certain hours. Through regulations that specified times and bells that marked the day, city people began to develop a mentality that conceived of the universe in quantitative terms. Clocks were also symbols of a city’s prosperity. Beautiful and elaborate mechanical clocks, usually installed on the cathedral or town church, were in general use in Italy by the 1320s, in Germany by the 1330s, in England by the 1370s, and in France by the 1380s.

Mirrors The commercial revolution brought new consumer goods into Europe, including exotic materials such as African ivory, here made into an intricately carved mirror case showing a knight honoring his lady while a groom holds his horses, created for a wealthy customer. More ordinary people used mirrors as well, as seen in this wooden carving of a woman admiring herself in a mirror (right). The carving, called a misericord, decorated the underside of the seat in a choir stall in a church in Beauvais, France. Secular scenes of everyday life were often shown in misericords, but the carving may also represent the sin of vanity, often symbolized by a woman holding a mirror.

The commercial revolution created a great deal of new wealth, which did not escape the attention of kings and other rulers. Wealth could be taxed, and through taxation kings could create strong and centralized states. The commercial revolution also provided the opportunity for thousands of serfs to improve their social position. The slow but steady transformation of European society from almost completely rural and isolated to urban and relatively more sophisticated constituted the greatest effect of the commercial revolution that began in the eleventh century.

Even so, merchants and business people did not run medieval communities other than in central and northern Italy and in the county of Flanders. Kings and nobles maintained ultimate control over most European cities, such as Paris, London, and Córdoba. Most towns remained small, and urban residents never amounted to more than 10 percent of the total European population. The commercial changes of the eleventh through thirteenth centuries did, however, lay the economic foundations for the development of urban life and culture.
