Industrial Revolution

New England was key to the Industrial Revolution in the United States. The Blackstone Valley running through Massachusetts and Rhode Island has been called the birthplace of America's industrial revolution. In 1787, the first cotton mill in America was founded in the North Shore seaport of Beverly, Massachusetts as the Beverly Cotton Manufactory. The Manufactory was also considered the largest cotton mill of its time. Technological developments and achievements from the Manufactory led to the development of more advanced cotton mills, including Slater Mill in Pawtucket, Rhode Island. Towns such as Lawrence, Massachusetts, Lowell, Massachusetts, Woonsocket, Rhode Island, and Lewiston, Maine became centers of the textile industry following the innovations at Slater Mill and the Beverly Cotton Manufactory.

The Connecticut River Valley became a crucible for industrial innovation, particularly the Springfield Armory, pioneering such advances as interchangeable parts and the assembly line which influenced manufacturing processes all around the world. From early in the nineteenth century until the mid-twentieth, the region surrounding Springfield, Massachusetts and Hartford, Connecticut served as the United States' epicenter for advanced manufacturing, drawing skilled workers from all over the world.

The rapid growth of textile manufacturing in New England between 1815 and 1860 caused a shortage of workers. Recruiters were hired by mill agents to bring young women and children from the countryside to work in the factories. Between 1830 and 1860, thousands of farm girls moved from rural areas where there was no paid employment to work in the nearby mills, such as the Lowell Mill Girls. As the textile industry grew, immigration also grew. By the 1850s, immigrants began working in the mills, especially French Canadians and Irish.

New England as a whole was the most industrialized part of the United States. By 1850, the region accounted for well over a quarter of all manufacturing value in the country and over a third of its industrial workforce. It was also the most literate and most educated region in the country.

During the same period, New England and areas settled by New Englanders (upstate New York, Ohio's Western Reserve, and the upper midwestern states of Michigan and Wisconsin) were the center of the strongest abolitionist and anti-slavery movements in the United States, coinciding with the Protestant Great Awakening in the region. Abolitionists who demanded immediate emancipation had their base in the region, such as William Lloyd Garrison, John Greenleaf Whittier, and Wendell Phillips. So too did anti-slavery politicians who wanted to limit the growth of slavery, such as John Quincy Adams, Charles Sumner, and John P. Hale. The anti-slavery Republican Party was formed in the 1850s, and all of New England became strongly Republican, including areas that had previously been strongholds for both the Whig and the Democratic parties. New England remained solidly Republican until Catholics began to mobilize behind the Democrats, especially in 1928. This led to the end of "Yankee Republicanism" and began New England's relatively swift transition into a consistently Democratic stronghold in national elections.
