1777 – The state of Vermont, an independent republic after the American Revolution, becomes the first sovereign state to abolish slavery Only the southern states had a large number of slaves. Counting them as part of the population would greatly increase the political power of the South, but it would also mean paying higher taxes. It was a price that the southern states were willing to pay. They pleaded for the census of slaves. The northern states disagreed. Delegates are compromised. Each slave would count as three-fifths of a person. William Wilberforce was the key player in supporting the case in Parliament. In 1806/07, when the abolition campaign intensified, he made a breakthrough. The House of Commons and the Lords eventually passed laws that ended Britain`s participation in trade. The invoice received royal approval in March and the trade was made illegal from May 1, 1807.
It was now against the law for any British or British ship that is subject to the slave trade. 1817 – France bans the slave trade, but the ban was not banned until 1826 In the South, fire eaters – antebellum pro-slavery extremists – proposed repealing the law and legalizing the international slave trade in the United States. Historian Erskine Clarke writes that this call was “a shameless expression of their contempt for any sense of anti-slavery and part of his strategy to divide the nation and create a confederation of slaves. Among other things, the Fire-Eaters hoped that a reopened international slave trade would enshrine the North and that indignation in the North would lead white Southerners to unite and move towards secession.  Jay was the son of one of New York`s greatest slavers and, like Franklin himself, a slaver, even though he claimed that his property was a means of achieving a beneficent end: “I buy slaves and manasies at the right age, and if their faithful services have given proper reprisals.” He and Hamilton, whose youth in West India bittered him out of slavery, were one of the founders of the New York Manumission Society in 1785, which founded the New York African Free School in 1787. That year, during the debate on the Constitution, Governor Morris, one of the loudest opponents of slavery among the founding fathers, called slavery a “shameful institution” and “a curse of heaven over the states where he ruled.” 1862 – Usa
