Shivaji's kingdom, also known as the Maratha Empire, was divided into four provinces or administrative divisions. Each province was under the charge of a Subedar or Mamlatdar.

The Subedar or Mamlatdar:
The Subedar or Mamlatdar was a high-ranking official who was responsible for the administration and governance of the province. This position was similar to that of a governor or administrator. The Subedar had significant authority and power in their respective provinces and reported directly to Shivaji, the ruler of the Maratha Empire.

Responsibilities of the Subedar:
1. Revenue Collection: One of the primary responsibilities of the Subedar was the collection of revenue from the province. They oversaw the collection of taxes, land revenue, and other forms of income for the kingdom.

2. Law and Order: The Subedar was also responsible for maintaining law and order within the province. They were in charge of the local police force and the judicial system, ensuring that justice was served and maintaining peace and stability.

3. Administration: The Subedar handled the administrative matters of the province. This included the appointment and supervision of local officials, resolving disputes, and managing the day-to-day affairs of the region.

4. Defense: The Subedar played a crucial role in the defense of the province. They were responsible for the recruitment and training of soldiers, the construction and maintenance of forts, and the protection of the borders.

5. Communication with the Ruler: The Subedar acted as a liaison between the province and the ruler. They provided regular updates, reports, and recommendations to Shivaji, ensuring effective communication and coordination between the central authority and the provinces.

Conclusion:
In summary, Shivaji's kingdom was divided into four provinces, and each province was under the charge of a Subedar or Mamlatdar. These officials held significant power and authority in their respective provinces and were responsible for various aspects such as revenue collection, law and order, administration, defense, and communication with the ruler.
