The main town in the district is St Helens, the others being Newton-le-Willows and Earlestown. Until the Industrial Revolution, the area was largely rural. Coal mining began in the 16th century, but modern industrial development began with the construction of the Sankey Canal in the late 18th century, linking St Helens with the River Mersey. The early 19th century saw new industries, including copper smelting, production of alkali, and the manufacture of glass. Of these, the major industry was glass making, the main business being that of Pilkingtons. The first major railway line in the world, the Liverpool and Manchester Railway was built through the district, opening in 1830.
