The process of freeing black slaves in the North occurred gradually, primarily during the late 18th and early 19th centuries. Many Northern states began to abolish slavery after the American Revolution, with Pennsylvania passing a gradual emancipation law in 1780. By the 1820s, most Northern states had either abolished slavery outright or enacted laws for gradual emancipation, effectively leading to the end of slavery in the North by the mid-1800s.
