10 MAY 1869 · THE INDUSTRIAL REVOLUTION, 1750–1914

The moment in context

America’s industrial rise began before the Civil War, and its first stage was tied to slavery and to Britain. Samuel Slater, who had memorised the inventor Richard Arkwright’s spinning machines in England, began spinning cotton in Rhode Island in 1790, and in 1823 a group of Boston merchants began production at Lowell in Massachusetts, a planned factory town whose mills hired young women from New England farms, who struck against wage cuts in 1834 and 1836. The cotton these mills spun came from the slave South, where the enslaved population grew from about 700,000 in 1790 to almost four million in 1860. The Civil War of 1861–65 destroyed slavery and confirmed the power of the industrial North, because its factories and railways outproduced the South’s. Emancipation freed four million people, yet most of them remained poor farm workers and sharecroppers, tenants who paid their rent with a share of the crop, in a South kept poor and segregated.
