Ryotwari system of revenue collection in India, introduced by the British, was based on the _______.

The correct answer is the Ricardian theory of rent.

The Ryotwari system of land revenue collection was introduced by the British in India, primarily associated with Thomas Munro and Read in the early 19th century. It was prevalent in regions like Madras (Tamil Nadu), Bombay (Maharashtra), parts of Assam, and Coorg. To understand why it was based on the Ricardian theory of rent, let us first understand what that theory says.

Step 1 – Understanding the Ricardian Theory of Rent:
David Ricardo (1772–1823), the classical British economist, proposed his famous theory of rent in his work Principles of Political Economy and Taxation (1817). The core idea of Ricardian rent is:

Rent arises due to the differential fertility of land. Ricardo argued that as population grows, cultivation is extended from more fertile land to less fertile (marginal) land. The marginal land (the least productive land under cultivation) earns no rent, while better-quality land earns rent equal to the difference in productivity between that land and the marginal land.

In simple terms:
Rent = Output from superior land − Output from marginal (no-rent) land

Rent is thus a surplus over and above the cost of production, determined by the quality and productivity of the land.

Step 2 – How the Ryotwari System Reflected Ricardian Principles:
Under the Ryotwari system, land revenue was assessed and collected directly from individual peasants (ryots), with no intermediary zamindars or landlords. The key features that align it with Ricardian theory are:

• Land classified by fertility/productivity: Land was surveyed and classified based on its quality and productive capacity — fertile, medium, or poor. This directly mirrors Ricardo's concept of differential land quality.

• Revenue proportional to surplus: The revenue demand was fixed as a share of the estimated produce or net produce of the land, essentially capturing the surplus (economic rent) that the land generated above subsistence costs — exactly the Ricardian definition of rent.

• No fixed intermediary — rent goes to the state: Since the state collected rent directly, it acted as the landlord appropriating the differential surplus that Ricardo described, without sharing it with any zamindar class.

• Revision based on productivity changes: Settlements were periodically revised to reflect changes in land productivity and prices, consistent with the idea that rent is dynamic and linked to the productive capacity of land.

Step 3 – The Intellectual Connection:
The British administrators, especially James Mill (who was heavily influenced by Ricardo and worked at the East India Company), explicitly used Ricardian rent theory as the theoretical justification for the state appropriating land revenue in India. Mill argued that since all land rent in Ricardo's framework is an unearned surplus, the colonial state was entitled to claim it as revenue — making the Ryotwari system a direct policy application of Ricardian economics in a colonial context.

Step 4 – Why the Other Options Are Incorrect:
• Smith's theory of rent: Adam Smith had an earlier, less systematic view of rent as simply the price paid for the use of land — not linked to differential fertility. The Ryotwari system's classification-based, surplus-extraction approach does not match Smith's framework.
• Malthusian theory of rent: Malthus had a theory of rent closely related to Ricardo's but emphasized population pressure on food supply as the driver. While Malthus influenced British thinking, the direct theoretical basis for Ryotwari's revenue calculation mechanism is Ricardian.
• Marx's theory of rent: Marx analyzed rent as a product of capitalist exploitation, categorizing it into absolute rent and differential rent. This came well after the Ryotwari system was established and was never a basis for British colonial revenue policy.

Conclusion:
The Ryotwari system was rooted in the Ricardian theory of rent because it assessed land revenue based on the differential productive capacity of land and extracted the surplus (economic rent) directly from cultivators, with the state acting as the ultimate landowner — a direct translation of Ricardo's theoretical framework into colonial land revenue policy.
