The Luddites were members of a 19th-century movement of English textile workers who protested the usage of certain types of automated machinery owing to their concerns relating to worker pay, labour savings, child labour, working conditions, and output quality. They often destroyed said machines in organised raids. Members of the group referred to themselves as Luddites, self-described followers of “Ned Ludd”, a legendary weaver whose name was used as a pseudonym in threatening letters to mill owners and government officials.
