African slave Trade, 1730
Excerpt from The Quaker Province: 1681-1776
Despite Quaker opposition to slavery, about 4,000 slaves were brought to Pennsylvania by 1730, most of them owned by English, Welsh, and Scotch-Irish colonists. The census of 1790 showed that the number of African Americans had increased to about 10,000, of whom about 6,300 had received their freedom. The Pennsylvania Gradual Abolition Act of 1780 was the first emancipation statute in the United States.
