カルナータカ太守
A period of anarchy followed the death of Tukkoji and came to an end when Pratapsingh came to the throne in 1739. He ruled until 1763. He allied with Muhammad Ali, the Nawab of the Carnatic, and aided the British East India Company against the French East India Company in the Carnatic Wars and the Seven Years' War. He was the last king to be addressed to be the Directors of the British East India Company as "His Majesty". In 1762, a tripartite treaty was signed between Thanjavur, Carnatic and the British by which he became a vassal of the Nawab of the Carnatic.
