Feudal Economic Expansion: Population, Agriculture, and Trade (10th-14th C.)
Characteristics of Feudal Economic Expansion (10th-14th Centuries)
Economic Growth
Economic growth during this period was extensive but short-lived and often reversible. Increased production relied more on expanding cropland and family-based production units than on capital investment or improved efficiency. This made it susceptible to the law of diminishing marginal productivity, especially in agriculture. The 10th-13th centuries saw considerable growth, followed by a decline in both product and population due to the Black Death in the 14th-15th centuries.
Population Growth
Population growth resulted from modest gains over three centuries with few serious epidemics or food crises. Cities and towns grew faster than rural areas. Early marriage, by extending fertility periods, contributed to positive natural balances despite high mortality. Abundant land provided opportunities for new families, leading to significant agrarian colonization across Europe. Cropland expanded through reclamation, sometimes by nobles but mostly by peasants.
Technological Change
Increased agricultural output also stemmed from technological advancements. Innovations from the Roman era and early Middle Ages culminated in the 12th century in a new agricultural system. This system integrated energy equipment, cultivation organization, animal energy control (through herding), and hydraulic systems (watermills and later windmills). Iron improved farming tools, and crop rotation, land allotment, and community coordination enhanced organization. While these innovations increased land and labor productivity, they may also have served territorial interests by facilitating tax collection. These advancements spurred technological change in other areas like transport, metallurgy, and textiles, particularly in populated regions and around cities where market proximity reduced transport costs and increased capital supply.
The Lordship
Throughout the Middle Ages, lordships experienced both internal transformation and increased engagement with foreign trade. Lords sought steady income rather than costly sacks. To attract settlers, they offered peasants favorable conditions. Lords also increasingly leased their reserves, shifting from labor and in-kind benefits to money rents and wage labor. Lordly revenue rose through fixed rents per unit area, rents proportional to crops (due to increased productivity), and rent updates reflecting land scarcity.
The Peasantry
Peasants had greater economic incentives, including management autonomy and surplus disposal, especially near cities. In newly colonized areas, they could even acquire land. Peasant cooperation within rural communities was strengthened by the technical demands of agricultural systems and defense against lordly demands. However, the peasantry wasn’t homogenous. Those with more land, capital, or demographic luck could accumulate wealth, while others had to work part-time for neighbors or lords, or migrate to cities.
Urbanization and the Commercial Revolution
The emergence of new cities and a growing population stemmed from increased agricultural productivity. Medieval towns expanded beyond late antiquity patterns. Within the feudal context of fragmented sovereignty and privilege, cities held a separate legal status. The urban revolution created a virtuous circle: market protection and personal freedom for the urban population fueled economic growth. Merchants, through professional corporations, could claim property rights and legitimize profit, challenging traditional societal and church views.
Trade expansion resulted from improvements in land and sea transport, but primarily from a growing money supply and institutional changes known as the commercial revolution. Key aspects include institutional changes driven by market expansion and larger-scale commercial enterprises leading to trader specialization. Corporations formed, notably the commenda. Banking emerged among moneychangers, enabling transfers between accounts and banks, initially without fees or interest. The bill of exchange appeared in 12th-13th century Italy as a credit instrument allowing deferred payment and debt settlement among merchants.
Even the Church’s stance on usury shifted slightly. Consignativos contracts circumvented the prohibition of interest-bearing loans by framing interest as rent payments.
