VI. SLAVERY IN THE NORTH AND THE REVOLUTION
At the beginning of the Revolution, slavery was legal in all of the thirteen
colonies that would form the United States. Concentrations of slaves varied.
While more than half of South Carolina’s population was enslaved, slaves
constituted less than two percent of New Hampshire’s population. As this
suggests, most slaves lived south of Pennsylvania. But in 1790, after the
disruptions of the war, the evacuation of many slaves (or former slaves) with
the British army, and considerable manumissions by patriots, the first census
still counted about 37,000 slaves in the three middle states (New York, New
Jersey, and Pennsylvania), as well as some 14,000 free Blacks, many of whom
would have been slaves when the war began.
By 1810, slavery was dead or dying in the North. Four states had
abolished it outright in their constitutions or through judicial enforcement of
their constitutions,
and five had passed gradual abolition laws.
No slaves
became immediately free under these gradual emancipation laws. However,
the children of all slave women were born free, which meant that slavery was

code, adopted in early 1784, consolidating previous existing laws on race and slavery. The entire
gradual abolition provision read:
And whereas sound policy requires that the abolition of slavery should be effected as soon
as may be, consistent with the rights of individuals and the public safety and welfare,
Therefore, Be it enacted, That no negro or mulatto child, that shall, after the first day of
March, one thousand seven hundred and eighty-four, be born within this state, shall be
held in servitude, longer than until they arrive to the age of twenty-five years,
notwithstanding the mother or parent of such child was held in servitude at the time of its
birth; but such child, at the age aforesaid, shall be free; any law, usage, or custom to the
contrary notwithstanding.
