Before colonization, India was one of the biggest textile exporters in the world. The inhabitants of the Indus Valley Civilisation grew cotton during the 5th millennium–4th millennium BCE. They converted the cotton into threads, which were later used in fabrics. Also, since ancient times, India has been growing jute and exporting raw jute to the West.
