Shropshire History has some good resources on the county's old mines, particularly the lead mines around the Stiperstones that have long been one of this blog's obsessions.
Take this account of the politics of the lead-mining country:
Local political feeling ran strongly at times and elections were occasionally accompanied by violence between bands of rival villagers. The Hope Valley was a Tory stronghold whilst Snailbeach was staunchly for the Liberals.
The supporters of each party were in the habit of attempting to prove their superiority by punching the heads of their supposed inferiors.
