The Luddites were a secret oath-based organisation of English textile workers in the 19th century who formed a radical faction which destroyed textile machinery. The group is believed to have taken its name from Ned Ludd, a legendary weaver supposedly from Anstey, near Leicester. They protested against manufacturers who used machines in what they called "a fraudulent and deceitful manner" to get around standard labour practices. Luddites feared that the time spent learning the skills of their craft would go to waste, as machines would replace their role in the industry.

Many Luddites were owners of workshops that had closed because factories could sell similar products for less. But when workshop owners set out to find a job at a factory, it was very hard to find one because producing things in factories required fewer workers than producing those same things in a workshop. This left many people unemployed and angry.

The Luddite movement began in Nottingham in England and culminated in a region-wide rebellion that lasted from 1811 to 1816. Mill and factory owners took to shooting protesters and eventually the movement was suppressed with legal and military force, which included execution and penal transportation of accused and convicted Luddites.

Over time, the term has come to mean one opposed to industrialisation, automation, computerisation, or new technologies in general.
