The Industrial Revolution occurred between the late 18th and 19th centuries, beginning in Britain and spreading worldwide. It brought machinery, steam power, and factories that enabled mass production. This led to urbanization as many moved from rural to urban areas for work in the new factories. Advances like the steam engine, cotton gin, and loom boosted industries like textiles. New processes also emerged, such as Bessemer steel production and pasteurization, while inventors including Thomas Edison and Louis Pasteur made many innovations.
