Consider the following statements:

1. In the revenue administration of Delhi Sultanate, the in-charge of revenue collection was known as ‘ Amil’.

2. The Iqta system of Sultans of Delhi was an ancient indigenous institution.

3. The office of ‘Mir Bakshi’ came into existence during the reign of Khalji Sultans of Delhi.

Which of the statements given above is/are correct?

The correct option is 1 only.

Let us analyze each statement individually to determine its correctness:

Statement 1: In the revenue administration of Delhi Sultanate, the in-charge of revenue collection was known as ‘Amil’.
This statement is correct. During the Delhi Sultanate period, revenue officers called Amils (or Amalguzars) were appointed in parganas (district subdivisions) to assess and collect land revenue from farmers and peasants.

Statement 2: The Iqta system of Sultans of Delhi was an ancient indigenous institution.
This statement is incorrect. The Iqta system was not an ancient indigenous Indian institution. Instead, it was imported from the West Asian Islamic administrative practices (Persian and Arab systems). It was formally organized and introduced in India by Sultan Shams-ud-din Iltutmish to assign land grants (iqtas) to military commanders and nobles for collecting revenue and maintaining army units.

Statement 3: The office of ‘Mir Bakshi’ came into existence during the reign of Khalji Sultans of Delhi.
This statement is incorrect. The post of Mir Bakshi was the head of the military department during the Mughal Empire (established during the reign of Akbar), not during the Delhi Sultanate. In the Delhi Sultanate (including under the Khalji dynasty), the military department was called Diwan-i-Arz, headed by the Ariz-i-Mumalik.

Therefore, only Statement 1 is correct.
