Formerly an occasional tiger was met in the south-east of Aligarh, the north-east- of Nimbahera, and parts of Pirawa and Sironj. The total area of the princely state was 2553 sq. mi, with a total population in 1901 of 273,201. By treaty Tonk became a British protectorate in 1817. Following the Independence of India, Tonk acceded to the newly independent dominion of India on 7 April 1949. It was located in the region bordering present-day Rajasthan and Madhya Pradesh states that are now the Tonk district. History The founder of the state was Nawab Muhammad Amir Khan (1769–1834), an adventurer and military leader of Pashtun descent. Amir Khan rose to be a military commander in the service of Yashwantrao Holkar of the Maratha Empire in 1798. In 1806, Khan received the state of Tonk from Yashwantrao Holkar.
