 In the legal jurisdiction of England and Wales, Wales became unified with the kingdom of England; the "Principality of Wales" began to refer to the whole country, though it remained a "principality" only in a ceremonial sense.The Marcher Lordships were abolished, and Wales began electing members of the Westminster parliament.Prior to the British Industrial Revolution, which saw a rapid economic expansion between 1750 and 1850, there were signs of small-scale industries scattered throughout Wales.
