The Carnatic Sultanate also known as Carnatic State or Arcot State was a kingdom in southern India between about 1690 and 1855, ruled by a Muslim nawab under the legal purview of the Nizam of Hyderabad, until their demise. They initially had their capital at Arcot in the present-day Indian state of Tamil Nadu. Their rule is an important period in the history of the Carnatic and Coromandel Coast regions, in which the Mughal Empire gave way to the rising influence of the Maratha India, and later the emergence of the British India.
