It was also part of the Roman trade route till South India. The medieval Cholas conquered Konga Nadu in the 10th century. In the 15th century the region was ruled by the Vijayanagara empire and later by the Nayaks. Somewhere in the 18th century Coimbatore happened to come under the Kingdom of Mysore. Following the defeat of Tipu Sultan, the ruler of Mysore at the hands of the British, Coimbatore was annexed to the Madras Presidency in 1799. In the 19th century the cotton mills at Mumbai (then Bombay) experienced a sharp decline and simultaneously Coimbatore experienced a boom. Since then Coimbatore has become a very prosperous region for cotton textiles in India. After Independence, Coimbatore remained part of Madras State now known as Tamil Nadu.
