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

The Ryotwari system of revenue collection in India, introduced by the British, was based on the Ricardian theory of rent. This theory, proposed by David Ricardo, posits that rent is derived from the differences in the fertility of land and is a surplus earned by the landowner. The Ryotwari system, while not directly a product of Ricardo's theory, was influenced by the idea that revenue could be based on the productive capacity of land and the individual cultivator's output.
