The Mughal emperors wanted to control the nomadic pastoral tribes of Sind because:

Correct option is C

The correct answer is (C) they wanted to make them sedentary to enhance the imperial income

Explanation:
• The Mughal administrative system, especially the Zabti system, was heavily dependent on settled agriculture for land revenue (Mal).
• Nomadic and pastoral tribes were difficult to tax because they moved across borders and did not have permanent fields. By making them sedentary (settled), the state could measure their land and demand regular revenue.
• Furthermore, nomadic tribes in the frontier regions of Sind and Punjab often posed a security threat by raiding trade caravans or settled villages. Settling them helped in maintaining 'law and order' and securing the trade routes to Central Asia.
• The state often granted land to these tribes or encouraged Sufi shaikhs to establish 'khanqahs' which served as centers of settled life, effectively turning pastoralists into peasants.

Information Booster:
• This process of 'Peasantization' of tribes was a common feature of Mughal expansion into peripheral regions.
• The Mughals used both force and patronage (Mansabdari) to integrate tribal leaders.

Additional Knowledge:
• Proselytization (Option A): While the Mughals were Muslim, their state policy (Sulh-i-Kul) was generally not focused on forced conversions.
• Live-stock (Option D): While livestock was valuable, the primary interest of the Mughal state was always 'land revenue', which was the backbone of the imperial economy.
