Taluqdar refers to one who holds a territorial unit.

Explanation:
- Taluqdar is a term used in the Indian subcontinent, particularly during the Mughal and British periods. It refers to a person who holds a taluqa, which is a territorial unit.
- In the feudal system, the taluqdar was granted the right to collect revenue from the land and had administrative control over the taluqa. They were responsible for maintaining law and order, as well as providing military support to the ruling authority.
- The taluqdar system was established to ensure effective governance and revenue collection in the region. The taluqdars were considered local elites and played a significant role in the functioning of the administration.
- The taluqdars were often granted land as a reward for their loyalty or military service. They were expected to pay a portion of the collected revenue to the ruling authority, such as the king or emperor.
- The taluqdar's role was crucial in maintaining stability and order within their territorial unit. They were responsible for resolving disputes, maintaining infrastructure, and ensuring the welfare of the people living in their taluqa.
- The taluqdar system underwent changes during the British colonial rule in India. The British introduced the Permanent Settlement system, which transferred the revenue collection rights directly to the taluqdars. This led to the consolidation of land ownership and increased the power and wealth of the taluqdars.
- Over time, the taluqdar system became synonymous with the large landholding elite, who held significant political and economic power in their respective regions.
- Today, while the taluqdar system is no longer in practice, the term taluqdar is still used to refer to the historical landholding class in the Indian subcontinent.

In conclusion, a taluqdar refers to one who holds a territorial unit, and they played a crucial role in the governance and administration of their taluqa during the Mughal and British periods in the Indian subcontinent.
