“Luddite” is now a blanket term used to describe people who dislike new technology, but its origins date back to an early 19th-century labor movement that railed against the ways that mechanized manufactures and their unskilled laborers undermined the skilled craftsmen of the day.

The original Luddites were British weavers and textile workers who objected to the increased use of mechanized looms and knitting frames. Most were trained artisans who had spent years learning their craft, and they feared that unskilled machine operators were robbing them of their livelihood. When the economic pressures of the Napoleonic Wars made the cheap competition of early textile factories particularly threatening to the artisans, a few desperate weavers began breaking into factories and smashing textile machines. They called themselves “Luddites” after Ned Ludd, a young apprentice who was rumored to have wrecked a textile apparatus in 1779.

There’s no evidence Ludd actually existed—like Robin Hood, he was said to reside in Sherwood Forest—but he eventually became the mythical leader of the movement. The protestors claimed to be following orders from “General Ludd,” and they even issued manifestoes and threatening letters under his name.

The first major instances of machine breaking took place in 1811 in Nottingham, and the practice soon spread across the English countryside. Machine-breaking Luddites attacked and burned factories, and in some cases they even exchanged gunfire with company guards and soldiers. The workers hoped their raids would deter employers from installing expensive machinery, but the British government instead moved to quash the uprisings by making machine-breaking punishable by death.

The unrest finally reached its peak in April 1812, when a few Luddites were gunned down during an attack on a mill near Huddersfield. The army had deployed several thousand troops to round up these dissidents in the days that followed, and dozens were hanged or transported to Australia. By 1813, the Luddite resistance had all but vanished. It wasn’t until the 20th century that their name re-entered the popular lexicon as a synonym for “technophobe.”
