Scunthorpe emerged as a settlement in the early Bronze Age but did not grow significantly until 1859 when ironstone deposits were discovered. The discovery led to the development of an iron and steel industry and rapid population growth. While steel production remains important, the industry has shrunk with factory closures. Today Scunthorpe has a diversified economy including retail, but steel manufacturing by Corus is still a major employer. Scunthorpe United football club plays in the town and has experienced success in recent decades after long periods of struggle.
