During the colonial era and until the first quarter of the nineteenth century, the economy of the northeastern United States was largely based upon self-sufficient family units that made or grew what they needed and sold or bartered what they could not consume. At that time, local economies supported small-scale cottage industries in which both men and women produced goods in their homes while also tending to their farms and children. Although traditional, gender-based divisions of labor dictated women's tasks, the contributions of wives and daughters were vital to the economy of preindustrial communities. Their work was often recorded in family or shop accounts. The advent of Industrial Revolution, during the first quarter of the nineteenth century, shifted the base of production from the home to the factory. With the change in the organization of work, independent, skilled craftsmen were replaced with large factories utilizing technology and mass production to meet the demands of the growing consumer culture. The workers became beholden to the factory owners who established new rules of labor and production, taking control from the workers. Massachusetts working people also played a central role in shaping the Industrial Revolution. (CofT, p.1) Not only did they provide the labor on which these new industries depended, but they struggled to maintain a measure of control. This change occurred over time with women continuing to perform “outwork” at home, producing goods from materials distributed by factory owners. (Harvard Business School, Baker Library website) The textile industry, the heart of the Industrial Revolution, was born in Massachusetts, taking hold in cities such as Lowell, Lawrence, Hudson, New Bedford, among others. Factory workers were recruited from rural farming communities, from throughout New England. Men and women ventured in large numbers to the cities to help power the new industries. These workers, not only learned to operate machinery and, in many cases, to live independently from their families, but also organized the first labor unions, in an effort to gain a measure of control over their new work environment. Lowell became a major industrial center and by 1833 almost one third of its 12,000 citizens were employed in the textile mills. By the 1850’s Lowell had 19 mills and was the “nation’s foremost cloth producer and the second largest city in Massachusetts.” (CofT, p.7) A large proportion of these workers were women. The Lowell “mill girls” played a prominent role in “the labor movement that sought justice and economic security. They also began the struggle for women’s rights in the workplace that still continues.” (CofT, p.1) Millworkers played an important role in the push for a 10-hour working day, which eventually became law in ____ after numerous efforts _______??? The importance of the textile industry in Massachusetts prompted one of the leading manufacturers, Pacific Mills, to develop an educational package for use in schools. This package included a lengthy pamphlet and two "cabinets" containing samples of fibers--one for cotton, the other for wool. The samples showed how cotton and wool changed through each stage of the processing.
