The drafting of the Constitution reflected a growing divide between Northern and Southern states on the question of slavery in that slaves were considered or be counted as three-fifths of a person.
Although framers such as George Washington and Thomas Jefferson -who, by the way, owned slaves- opposed the institution of slavery, delegates during the Constitutional Convention of 1787 in Philadelphia Pennsylvania agreed on establishing a limit to allow slavery in the United States until 1808. This created more tense moments and divided the nation.
