Agriculture, Famine, and Rural Change in the Late Middle Ages
The rural economy of c. 1300–1500 did not drift into crisis so much as run out of room. A century of ploughing marginal land and converting forest and marsh to cereal had lifted Europe’s population from perhaps 38 million in 1000 to over 70 million by 1300, but the gains of the heavy plough, the horse collar, and the three-course rotation had by then been absorbed. When the rains failed in 1314 and did not stop until 1317, harvests collapsed in succession and the grain reserves of even wealthy abbeys were exhausted. The three articles in this section treat, in turn, the agrarian system that produced that vulnerability, the famine that exposed it, and the long commercial pivot toward pastoral farming that followed.
The Three-Field System and the Limits of Medieval Agronomy
The autumn-sown winter crop, the spring-sown spring crop, and the fallow that broke the cycle of weeds and soil exhaustion were already the standard rhythm across most of northern Europe by 1300. Yields of roughly 3:1 or 4:1 — three or four grains returned for every grain sown — were the norm on the demesne of manors such as those of the bishopric of Winchester or the Cistercian granges of the East Riding, and the system supported the demographic surge of the high Middle Ages. M. M. Postan, summarising a generation of English manorial accounting in his Cambridge Economic History essays, argued that the thirteenth century was an “age of diminishing returns”: each additional acre brought into cultivation yielded less than the last, while rents and seigneurial demands continued to rise. The demographic pressure of the 1200s thus produced not affluence but vulnerability, and it set the stage for the catastrophe of the 1310s. The detailed mechanics of the rotation — the open fields, the strips, the common grazing — are treated in the article on the three-field system and medieval crop rotation.
The Great Famine of 1315–1317 and the Malthusian Tipping Point
The failure of the 1314 harvest in much of England, northern France, the Low Countries, and western Germany set off three consecutive years in which the autumn sowing rotted in the field and the spring sowing was waterlogged or eaten by the survivors’ livestock. Contemporary chroniclers at the Cistercian abbey of Meaux in Yorkshire recorded 1316 as the year in which the living could no longer bury the dead. Cattle were slaughtered for lack of fodder, seed corn was eaten, and the price of wheat in Cambridgeshire rose to roughly four times its pre-famine level. Postan, and later William Chester Jordan in The Great Famine, framed this as a Malthusian crisis: a population pressed against resources with no margin left. The famine killed perhaps 5 to 10 per cent of the people of north-western Europe and left survivors physically weakened when plague returned in 1348–49 — a concatenation that John Hatcher has analysed in detail for the Northamptonshire village of Brigstock in his Plague, Population and the English Economy, 1348–1530.
Wool, Sheep, and the Commercialisation of the English Countryside
The recovery from plague shifted the rural economy decisively toward the market. As labour costs rose on the demesnes, lords abandoned direct cultivation, commuted labour services into money rents, and let their demesne lands to peasant tenants. The land itself was increasingly given over to sheep, whose wool fed the cloth industries of Florence, the Low Countries, and the Flemish towns. Edward III’s grant of 1337 to William de la Pole of a licence to export wool, and the later rise of the great “wool churches” of Lincolnshire, the Cotswolds, and the Pennines — funded by the tithes of the great Cistercian and Premonstratensian flocks — anchored a trade that turned English silver into Florentine and Genoese galleys. By the later fifteenth century, as John Munro and Christopher Dyer have both stressed, a partial rebalancing had occurred: population gently recovered after 1450, real wages for day-labourers held unusually high, and the rural poor in many parts of England ate a more varied and better diet than they had before 1300. The story of that transformation is told in the article on the wool trade and medieval England’s economy.
