Explanation:

In the Indian subcontinent, during the colonial period, the British East India Company introduced various systems of land revenue administration. These systems were implemented to establish control over land and extract revenue from the agricultural sector. Among these systems, the Zamindari system was one where the rent was fixed, and a revenue collector appointed by the government was responsible for rent collection.

Zamindari System:
The Zamindari system was introduced by the British during the Permanent Settlement of 1793. Under this system, the land was divided into large estates known as Zamindari. The Zamindars were appointed as revenue collectors and intermediaries between the government and the peasants. The Zamindars were given hereditary rights over the land, and they were responsible for collecting rent from the peasants and paying a fixed amount to the British government.

Key Features of the Zamindari System:
- Rent Fixation: In the Zamindari system, the rent was fixed, and the Zamindars were responsible for collecting this fixed rent from the peasants.
- Revenue Collection: The Zamindars acted as revenue collectors on behalf of the British government. They collected rent from the peasants and paid a fixed amount to the government.
- Hereditary Rights: The Zamindars were given hereditary rights over the land. This meant that the land could be passed down from one generation to another within the Zamindar family.
- Intermediaries: The Zamindars acted as intermediaries between the government and the peasants. They were responsible for maintaining law and order in their estates and resolving disputes among the peasants.
- Exploitative Nature: The Zamindari system was highly exploitative towards the peasants. The fixed rent was often set at a high rate, and the Zamindars used their power to extract maximum revenue from the peasants, leading to widespread poverty and indebtedness among the peasants.

Conclusion:
In summary, the Zamindari system was a land revenue administration system introduced by the British in which the rent was fixed, and a government-appointed revenue collector, known as the Zamindar, was responsible for collecting rent from the peasants. This system was highly exploitative and led to the impoverishment of the peasants.
