It hasn’t.

Most of it was made within the last two hundred and fifty years. Before that, the fields were open, unhedged, and worked communally. The hedges that seem so permanent, so natural, so characteristically English, were planted relatively recently.

This is where the agricultural revolution begins: not with a machine or an invention, but with a fence.

The open field system

To understand enclosure, you first need to understand what it replaced.

For most of the medieval and early modern period, farming in lowland England was organised around the open field system.

A typical village might have two or three large open fields, each subdivided into long narrow strips. Individual families farmed a scatter of strips across all the fields — not a single consolidated holding but a patchwork, interleaved with the strips of their neighbours. The system had a logic: spreading holdings across different fields spread the risk of a bad harvest in any one location.

Alongside the open fields, most villages had areas of common land (meadow, pasture, heath, fen) to which all inhabitants had traditional rights. The right to graze animals on the common. The right to cut peat for fuel. The right to gather wood. These common rights were not charity; they were a fundamental part of the rural economy, and for the poorest households they were the margin between subsistence and destitution.

This system was, by the standards of the agricultural improvers of the eighteenth century, hopelessly inefficient. Scattered strips made systematic improvement impossible. Common land was, in their view, underused. The animals grazing on it were often scrubby and diseased; the land itself was productive of nothing much at all. If agriculture was going to feed a growing population and generate the returns that the new capitalist economy demanded, it needed to be rationalised.

The instrument of rationalisation was enclosure.

What enclosure actually was

Enclosure — the consolidation of open fields and commons into private, bounded holdings — had been going on in a piecemeal way since the medieval period.

But the great wave of parliamentary enclosure, which transformed the landscape of lowland England, took place between roughly 1750 and 1850. During this period, around four thousand Enclosure Acts were passed by parliament, affecting some seven million acres of open field and common.

The process worked like this. The major landowners of a parish petitioned parliament for an Enclosure Act. Parliament passed it. Enclosure commissioners were appointed to survey the parish, assess existing rights and holdings, and draw up an award: a legal document allocating consolidated parcels of land to the various claimants in proportion to their previous holdings or rights. The common fields were divided. The common land was apportioned. New roads were laid out. New hedges and fences were planted.

And the open landscape that had existed for centuries was, within a few years, gone.

Who won and who lost?

The usual answer is that the large landowners won, and the rural poor lost. This is broadly true, though the details are more complicated.

Large landowners received consolidated holdings that could be farmed efficiently, improved with new techniques, and let to substantial tenant farmers on commercial leases. The agricultural improvers were right that enclosed and consolidated land was more productive: yields increased significantly over the century following enclosure.

Smaller landowners and freeholders received consolidated holdings too. But these were often too small to be viable. Burdened with the considerable costs of fencing and enclosing their newly allocated land, many sold up within a generation and joined the landless labouring class.

Cottagers and squatters were those who had relied on common rights but could not prove a formal legal claim. So received nothing. Their traditional rights simply ceased to exist. The common on which they had grazed a cow, gathered fuel, and pastured geese was now somebody else’s pasture field, hedged in and inaccessible.

The result was a landscape redrawn and a rural social structure fundamentally changed.

The English countryside moved, over the course of a century, from a landscape of small cultivators with customary rights to a landscape dominated by large tenant farms and a landless agricultural labouring class. The consequences for the rural poor were severe.

Why this matters for local history

Every county archive in England holds Enclosure Awards and enclosure maps for the parishes affected by parliamentary enclosure. These are extraordinary documents: large, detailed maps showing the landscape of a specific parish at the moment of enclosure, alongside a legal text listing every claimant, every allocation, every road, every boundary.

They are the birth certificate of the modern English countryside.

For local historians, the enclosure award is often the key to understanding the landscape that followed. The field names in a tithe map of 1840 frequently preserve the names of the old open field strips. The farmsteads that appear for the first time in the 1841 census, isolated in the middle of newly hedged fields, were often built as part of the enclosure process. The spike in poor relief payments in a parish vestry book in the decade after enclosure tells the human cost of the transformation.

In the next issue in this series, we’ll look at the Enclosure Acts themselves in detail — how to find them, how to read them, and what they tell you about the parish you’re researching.
