The Luddites were 19th-century English textile workers (or self-employed weavers who feared the end of their trade) who protested against newly developed labour-economizing technologies, primarily between 1811 and 1816. The stocking frames, spinning frames and power looms introduced during the Industrial Revolution threatened to replace them with less-skilled, low-wage labourers, leaving them without work. The Luddite movement culminated in a region-wide rebellion in Northwestern England that required a massive deployment of military force to suppress.
