List of Diwans of Mysore
The Maharajas of Mysore founded the kingdom in 1399 with a brief interruption in the last two decades of the 18th century. After Tipu Sultan, the concept of Diwans was conceived in the Kingdom, with Diwan Purnaiah as the first ever Prime Minister of the Kingdom of Mysore, who was a diwan for Tipu Sultan, and after the end of the Sultans, to the Maharaja of Mysore His Highness Krishnaraja Wadiyar III. The word Dewan means the Prime Minister of a kingdom; more precisely, a royal advisor to the monarch.
The following lists the Diwans of Kingdom of Mysore through 1799 to 1947. The most notable of the diwans are: Diwan Purnaiah, Diwan Sir C. V. Rungacharlu, Diwan Sir K. Seshadri Iyer, Diwan Sir P. N.
