Sher Shah's empire was divided into 47 Sarkars.

Explanation:
Sher Shah Suri, also known as Sher Shah or Sher Khan, was the founder and ruler of the Sur Empire in North India. He reigned from 1540 to 1545 and is known for his administrative reforms and construction of infrastructure, such as the Grand Trunk Road.

During his rule, Sher Shah divided his empire into administrative divisions called Sarkars. These Sarkars were further subdivided into Parganas, which were smaller units of governance.

The division of the empire into Sarkars was a part of Sher Shah's administrative reforms. It helped in effective governance and revenue collection. Each Sarkar had its own administrative structure, with a Sarkar officer known as a Sarkar-i-Khalisa responsible for the administration and revenue collection.

The total number of Sarkars in Sher Shah's empire was 47. These Sarkars covered various regions of the empire, including present-day Bihar, Uttar Pradesh, Madhya Pradesh, and parts of Rajasthan and Punjab.

The division of the empire into Sarkars allowed for better governance and efficient administration. It ensured that the empire was effectively managed and revenue was collected from different regions. The Sarkar system also facilitated the implementation of Sher Shah's land revenue reforms, which aimed at a fair assessment and collection of revenue from the agricultural sector.

Overall, the division of Sher Shah's empire into 47 Sarkars was an important administrative measure that contributed to the efficient governance and revenue management of the Sur Empire.
