Slavevery in Africa lasted for aboutyears

Slavery lasted in about half of U.S. states until 1865. As an economic system, slavery was largely replaced by sharecropping and convict leasing. By the time of the American Revolution (1775–1783), the status of enslaved people had been institutionalized as a racial caste associated with African ancestry.

In January 1807, with a self-sustaining population of over four million enslaved people in the South, some Southern congressmen joined with the North in voting to abolish the African slave trade, an act that became effective January 1, 1808.
