The town lies close to the route of the ancient Watling Street, and although there is no record of its existence before the 17th century, Ogley Hay – a district of the town today – is recorded as a settlement in the Domesday Book. Brownhills quickly grew around the coal-mining industry, especially after the town became linked to the canal and railway networks in the mid-19th century. By the end of the century Brownhills had grown from a hamlet of only 300 inhabitants to a town of more than , of whom the vast majority were employed in the coal industry. Mining remained the town's principal industry until the 1950s; the subsequent closure of the pits led to a severe economic decline that has continued until the present. The local authority instituted a regeneration programme in 2007, which was hoped would revive the town's fortunes, but there has been little subsequent development.
