Few of the industrial workers, of course, had the vote since they were not property owners, and in the early 19th century political unrest was common - most notably the "Pentrich Revolution" or "Derbyshire Rising" of 1817. Derbyshire soon became one of the most vocal centres of agitation for Parliamentary reform, and by 1830 this sentiment had spread to the voters as well. At the 1831 election their sitting Tory MP was summarily swept out of his seat for supporting a destructive amendment to the Reform Bill.
