Carnatic Wars
Kanchipuram was a battlefront for the British East India Company in the Carnatic Wars against the French East India Company and in the Anglo-Mysore Wars with the Sultanate of Mysore.The popular 1780 Battle of Pollilur of the Second Anglo-Mysore War, known for the use of rockets by Hyder Ali of Mysore, was fought in the village of Pullalur near Kanchipuram. In 1763, the British East India Company assumed indirect control from the Nawab of the Carnatic over the erstwhile Chingleput District, comprising the present-day Kanchipuram and Tiruvallur districts, in order to defray the expenses of the Carnatic wars. The Company brought the territory under their direct control during the Second Anglo-Mysore War, and the Collectorate of Chingleput was created in 1794. The district was split into two in 1997 and Kanchipuram made the capital of the newly created Kanchipuram district.
