Of the Discouragement of Agriculture in the Ancient State of Europe

Core idea

After the fall of the Roman Empire, the natural progress of agriculture — the first and most productive employment of capital — was systematically blocked in Europe by three institutional features:

1. Primogeniture — the rule that all land descends to the eldest son, keeping enormous estates undivided across generations.
2. Entails — legal restrictions forbidding the current owner from selling, mortgaging, or alienating land away from a designated line of inheritance.
3. Serfdom and villenage — labour systems in which the cultivators of the land were not free people who could profit from improvement, but bondsmen whose surplus belonged to the lord.

Together these three institutions created a system in which vast estates were held by people with no incentive or power to improve them, and worked by people with no incentive or right to improve them. The most productive employment of capital — agriculture — was therefore the slowest to develop in Europe, exactly the opposite of what the natural progress would have predicted.

Why it matters

The topic is Smith's most pointed institutional analysis in Books I-III. It is one of the great early statements of the modern view that institutions, not resources, drive long-run economic outcomes. Two and a half centuries later, this is the central claim of New Institutional Economics — Smith was there first.

Primogeniture: a feudal artefact preserved past its purpose

In the chaos that followed the fall of Rome, primogeniture made some sense. A great estate was simultaneously a military command, a political jurisdiction, and a source of subsistence. Dividing it among heirs would have produced fragments incapable of defending themselves; concentrating it on one heir kept it strong. Smith concedes the original logic.

What he condemns is its persistence centuries after the military function had passed to the state. By the 18th century, primogeniture no longer protected anything — it simply locked land into the hands of a single heir whose interests might have nothing to do with the land's productive use. The institution outlived its rationale by perhaps five hundred years.

Entails: paralysis by ancestor

Entails compound the problem. A current owner under an entail cannot sell off poor land to invest in better, cannot mortgage to fund improvements, cannot consolidate scattered holdings, cannot give portions to younger children. The dead hand of an ancestor governs decisions that ought to be made by living owners responding to current opportunities.

Smith treats entails as the more egregious of the two. Primogeniture is at least defensible historically; entails are simply legal absurdities that have outlived their original purpose.

Serfdom: no incentive at the labouring end

Even if the lord had wanted to improve the land, the labourers had no reason to help. A serf received subsistence from his master and gave back whatever the master demanded; any surplus he produced went to the master, not to himself. Improvement of the soil, careful husbandry, willingness to try new crops — all required investment of effort that yielded no return to the person making it.

Where serfdom was replaced by metayage (sharecropping, where lord and tenant split the produce), incentives improved slightly — the tenant kept half of what he produced — but the lord still bore all the capital risk, and the tenant rarely had the security to invest his own capital in fixed improvements.

Only free tenants with long leases at fixed rents — and ultimately free landowners working their own land — had the right incentive structure: any productivity gain accrued to the person making the investment. Smith treats this as one of the great institutional innovations of post-medieval Europe, slow and uneven though it was.

The persistence of large idle estates

The composite effect: medieval and early modern Europe was characterised by enormous estates owned by people who had no taste or training for agricultural management, worked by people who had no incentive to improve, with land that could neither be subdivided nor sold to anyone who might have done better. The most productive employment of capital was therefore the least developed.

This is the institutional answer to the puzzle posed in Book III, Topic 1: Of the Natural Progress of Opulence: why did Europe's wealth grow first in cities and through commerce, when the natural sequence would have placed agriculture first? Because agriculture was institutionally prevented from developing first.

Practical application

The topic is the conceptual root of modern land-reform policy debates in developing countries. Countries that have undergone successful land reforms — South Korea, Taiwan, post-WWII Japan — broke up large estates, granted secure tenancy or ownership to cultivators, and saw rapid productivity gains in the following decades. Countries that have left feudal-equivalent land tenure intact — much of South Asia, parts of Latin America, parts of post-Soviet Central Asia — have struggled to develop their agricultural base, with knock-on effects on urbanisation, manufacturing, and overall growth.

The general principle survives: secure, alienable, well-defined property rights, held by people who can profit from their improvement, are a precondition for productivity gains. Wherever any of these conditions fails — through inheritance restrictions, expropriation risk, communal ownership without individual incentive, or labour bondage — productivity gains will lag the economic potential of the resource.

Example

The 1949-1952 land reform in Japan transferred ownership of agricultural land from absentee landlords to the actual cultivators, with strict limits on how much any one person could own and tight restrictions on accumulating large holdings. Within two decades, Japanese agricultural productivity rose dramatically — not because the soil changed, the climate changed, or the seeds changed, but because the people working the land now received the gains from their own improvements. The same workers, on the same fields, producing far more under different institutional arrangements. Smith's argument, validated by a 20th-century natural experiment.
