In modern usage, Luddite is defined as one who opposes new technology. The term comes from the group of English mechanics and artisans who, in 1811, organized a protest that involved destroying new manufacturing machinery which they perceived as threatening their livelihoods. They named themselves after Ned Ludd—sometimes known as Captain Ludd, King Ludd, or General Ludd—a mythical 18th-century character known for sabotaging knitting machinery. British government crackdowns quashed the movement within a few years of its start, but the term lives on. It’s often pejorative.
Luddite functions as both a noun and an adjective. Luddism is the term for the attitudes that characterize Luddites. The L in Luddite is usually capitalized, though this may change if the word remains in the language another few decades.
