The Luddites were textile workers in Nottinghamshire, Yorkshire and Lancashire, England. They were skilled artisans whose trade and communities were threatened by a combination of machines and other practices that had been unilaterally imposed by the aggressive new class of manufacturers that drove the Industrial Revolution. Stocking frames, spinning frames and power looms introduced during the Industrial Revolution between 1811 and 1816 replaced the Luddites with less-skilled, low-wage laborers, leaving the Luddites without work. The Luddite movement culminated in a region-wide rebellion in Northwestern England that required a massive deployment of military force to suppress the rebellion.
