Answer: Mumbai
Notes: Mumbai was called the 'Manchester of the East' for its cotton textile industry. The first cotton mill, Bombay Spinning Mill, opened in 1854. By the early 20th century, Mumbai had around 130 textile mills, mainly in Girangaon. The city's mills were supported by port access, railways, and suitable climate for spinning. Mumbai became India's largest cotton textile center in the 19th century.
