The Lowell mill girls were young female workers who came to work in industrial corporations in Lowell, Massachusetts, during the Industrial Revolution in the United States. The workers initially recruited by the corporations were daughters of New England farmers, typically between the ages of 15 and 35. By 1840, at the height of the Textile Revolution, the Lowell textile mills had recruited over 8,000 workers, with women making up nearly three-quarters of the mill workforce.
