From Wikipedia:
The Luddites were a group of English workers in the early 1800s who protested against the changes produced by the Industrial Revolution that they felt threatened their jobs, often by destroying machines.
The original Luddites claimed to be led by one Ned Ludd, also known as "King Ludd", who is believed to have destroyed two large stocking-frames that produced inexpensive stockings undercutting those produced by skilled knitters, and whose signature appears on a "workers manifesto" of the time. Whether or not Ludd actually existed is historically unclear.
The movement spread rapidly throughout England in 1811, with many wool and cotton mills being destroyed, until the British government harshly suppressed them. This included making "machine breaking" (industrial sabotage) a capital crime, and executing 17 men in 1813. At one time, there were more British troops fighting the Luddites than Napoleon Bonaparte.
In recent years, the terms Luddism and Luddite or Neo-Luddism and Neo-Luddite have become synonymous with anyone who opposes the advance of industrial technology.
Now those of us that are historically challenged know what a luddite is.
