"The British provincial rulers divested the Nawab of his title and his jurisdictional authority following the Company’s defeat of Tippu and its annexation of his Caranatic holdings. The Nawab and his descendants were granted a title (The Prince of Arcot) and pension, and a portion of the estate was allocated for their use. The estate’s main palace, the Chepauk Palace, was purchased by the British administration in 1855 and converted to government offices, and it continues to be used in this way."
