The Enclosures in England: An Economic Reconstruction

In Short

Harriett Bradley Fitt’s monograph reconstructs the economic drivers behind the English enclosure movement, challenging the long-accepted historical theory that land was enclosed primarily to capitalize on lucrative wool prices. By analyzing price statistics, harvest yields, and manorial court records from the fourteenth through eighteenth centuries, Fitt demonstrates that the conversion of arable open fields into enclosed pastures was fundamentally caused by soil exhaustion. The book remains a foundational historical reinterpretation, proving that medieval agricultural practices systematically depleted the soil, forcing landowners and tenants to convert exhausted tillage into pasture until its fertility could naturally recover.

The Story

The prevailing historical consensus regarding English agrarian history asserts a straightforward economic chain of events: a boom in the domestic and international woollen industry drove wool prices up, prompting profit-seeking landlords to evict arable farmers, enclose common fields, and convert crops to sheep pasture. Fitt opens her inquiry by rigorously testing this hypothesis against historical price data and manorial records, discovering that the narrative is fundamentally flawed. Statistical evidence shows that during the primary periods of enclosure in the fifteenth and sixteenth centuries, wool prices actually fell relative to grain prices. Furthermore, land conversions were already well underway before the Black Death and continued independent of population shifts, labor wage spikes, or international market demands.

If relative prices and labor shortages cannot account for the widespread abandonment of tillage, Fitt argues, historians must look to the physical condition of the land itself. Turning to agricultural science and manorial harvest records from estates like Witney and the Winchester group, she illustrates a stark reality: centuries of continuous cultivation under the open-field system, combined with a chronic lack of animal manure, steadily drained the soil of essential nitrogen and organic nutrients. By the fourteenth century, crop yields had plummeted to unsustainable levels. Land holding had ceased to be a profitable enterprise; serfs and customary tenants actively paid fines or fled their villages to avoid being forced into taking up barren holdings. Landlords were left with vacant, unproductive demesnes that could no longer support traditional husbandry or pay basic rents.

Enclosure emerged not as a predatory venture to seize wool profits, but as an inescapable ecological and economic necessity. To survive, farmers began consolidating scattered strips, plowing under turf boundaries, and laying exhausted arable land down to grass as "lea land." Small tenants and large manorial lords alike were forced to hedge their holdings and convert barren fields into pasture, using livestock grazing to slowly restore the soil's organic equilibrium.

The eventual return of tillage in the seventeenth and eighteenth centuries confirms Fitt's thesis. Once enclosed pastures had "gotten heart, strength and fruitfulness" through prolonged rest, landowners voluntarily plowed them up to sow grain once again, long before formal parliamentary enclosure acts took hold. Fitt closes her reconstruction by showing that the enclosure movement was ultimately a cyclical process of soil exhaustion and regeneration, fundamentally reshaping English social and legal history through the imperative of land survival.

How It Unfolds

The wool price myth breaks down Fitt compiles historical price data for wheat and wool across the fifteenth and sixteenth centuries, demonstrating that wool prices were falling relative to grain during the height of the enclosure movement. This statistical reality directly contradicts the orthodox theory that lucrative wool markets lured landlords away from agriculture.

The soil loses its fertility Examining manorial harvest yields from the thirteenth and fourteenth centuries alongside soil chemistry, the text shows that medieval open-field farming steadily depleted the land of nitrogen and organic matter. Continuous cropping without adequate manure caused wheat yields to collapse, rendering traditional tillage unprofitable.

Peasants flee unproductive holdings Declining fertility made it impossible for customary tenants to support their families or perform required labor services. Manorial records reveal that villains regularly paid fines to refuse inherited lands, deserted their manors, or forced village communities to compel reluctant individuals to accept vacant, impoverished holdings.

The open fields disintegrate Faced with falling productivity, farmers began consolidating scattered land strips, plowing up turf boundaries, and laying worn-out arable land to grass. This practice created "lea land" within the open fields, shifting land temporarily from crop production to grazing to give the soil crucial rest.

Enclosure and soil recovery succeed Landlords and tenants enclosed fields to manage grazing and protect recovering land, leading to temporary sheep pasture. Once the soil regained its natural strength over decades of rest, farmers voluntarily reconverted the land back to arable farming, establishing a sustainable cycle of soil restoration.

The People

Harriett Bradley Fitt The author and economic historian who acts as the primary analytical guide throughout the work. Fitt approaches the historical record with quiet, methodical precision, aiming to replace accepted historical assumptions with empirical evidence derived from price tables, manorial rolls, and agricultural science.

The Medieval Villain (Customary Tenant) The struggling peasant worker of the open-field system. Far from seeking social mobility or market profits, the villain is driven by basic survival; trapped on deteriorating land that no longer yields enough grain to pay dues or feed a family, the villain frequently chooses flight, poverty, or legal fines over forced land tenure.

The English Landlord The manorial owner caught between rising living costs and declining agrarian revenues. Unable to extract profit or rent from exhausted demesne lands under the traditional open-field system, the landlord is forced to alter traditional estate management, convert barren fields to pasture, and eventually enclose land to raise revenues.

Early Agrarian Commentators (Fitzherbert, Tusser, and Hales) Historical contemporaries whose sixteenth-century treatises and dialogues capture the transition on the ground. Fitzherbert and Tusser observe the practical necessity of turning worn-out arable land to grass, while John Hales voices the political and social alarm over depopulation and enclosed pastures.

In Its Own Voice

"It fareth with the earth as with other creatures that through continual labour grow faint and feeble-hearted."

In a 1597 House of Commons speech, a member commends legislation that allows exhausted arable fields to rest as pasture so they may gather strength.

"Land arable driuen or worne to the proofe, and craveth some rest for thy profits behoof, With otes ye may sowe it the sooner to grasse more sooner to pasture to bring it to passe."

Thomas Tusser’s sixteenth-century agricultural verse reflects the practical necessity of converting depleted crop land into temporary grazing pasture.

"As the want thereof [of corn] shall appear, or the price thereof increase, all or a great part of those lands which were heretofore converted from errable to pasture and have sithence gotten heart, strength and fruitfulness, will be reduced to Corne lands againe..."

A 1619 royal commission proclamation recognizes that previously enclosed pasture lands had recovered their natural fertility and were being returned to crop cultivation.

What It's Really About

Beneath its statistical tables and historical citations, the work addresses the fundamental relationship between human agricultural systems and ecological constraints. It argues that economic institutions, legal arrangements, and tenant contracts do not exist in a vacuum; they are bound to the biological health of the soil. When medieval farming practices pushed the land beyond its natural limits, the manorial system collapsed not because of political revolution or sudden market incentives, but because the earth itself could no longer support the population under existing methods. The book demonstrates how long-term environmental degradation forces profound structural, legal, and economic reorganization, transforming how societies manage property, labor, and community rights.

Why Read It Today

Fitt’s study remains a compelling read for anyone interested in economic history, historical ecology, or the origins of modern agricultural property rights. Reading the book feels like watching a careful detective unravel a centuries-old historical misconception using cold, hard data. Rather than relying on sweeping generalizations, Fitt builds her case block by block, pairing agrarian chemistry with medieval manorial rolls.

The text does present clear period difficulties. It is an academic treatise from 1918, unsparing in its use of historical estate data, Latin court entries, and statistical yield comparisons. Readers must navigate references to virgates, demesnes, and sixteenth-century husbandry statutes. Yet, for those willing to engage with its academic rigors, the monograph offers an elegant lesson in historical methodology. It leaves the reader with a permanent appreciation for how ecological realities quiet logic behind historical choices, offering a sobering reminder that economic systems are ultimately anchored to the health of the physical environment.
