After the partition of India in 1947, the Punjab province of British India was divided between India and Pakistan. The Indian Punjab was divided on the basis of language in 1966. It was divided into 3 parts. Haryanvi speaking areas (dialect of Hindi) were carved out as Haryana, Hilly regions and Pahari speaking areas formed Himachal Pradesh alongside the current state of Punjab. Punjab is the only Sikh majority state in India with Sikhs being 57.69% of the population. Agriculture is the largest industry in Punjab.
Other major industries include the manufacturing of scientific instruments, agricultural goods, electrical goods, financial services, machine tools, textiles, sewing machines, sports goods, starch, tourism, fertilisers, bicycles, garments, and the processing of pine oil and sugar. Punjab has the largest number of steel rolling mill plants in India, which are located in "Steel Town"—Mandi Gobindgarh in the Fatehgarh Sahib district.
