By the time that the nation of America was founded, slavery was dying in the north. While there were doubts in the south too, few could conceive the economic alternatives. In 1793, the introduction of Eli Whitney's cotton gin made slavery more profitable in the southern cotton plantations. As production soared, the demand for slaves increased. By 1860 and the eve of the war, four million men, women and children were slaves. In Boston in 1871, William Lloyd Garrison started publication of a militant anti-slavery newspaper, 鈥淭he Liberator鈥�. He called for immediate abolition.
