In the late eighteenth century, slavery prevailed throughout much more than half the lands of Europe. Jefferson designed the ordinance to establish from end to end of the whole country a north and south line, at which the westward extension of slavery should be stayed by an impassable bound. On exactly the ninth anniversary of the fight at Concord and Lexington, Richard Dobbs Spaight of North Carolina, seconded by Jacob Read of South Carolina, moved to strike out the fifth article concerning the restriction on the expansion of slavery. The votes of seven states were needed to approve Jefferson's clause. From a letter from Jefferson to James Madison, dated April 25, 1784: "The clause was lost by an individual vote only. Ten states were present. The four eastern states, New York, and Pennsylvania were for the clause; Jersey would have been for it, but there were but two members, one of whom was sick in his chambers. South Carolina, Maryland, and Virginia voted against it. North Carolina was divided, as would have been Virginia, had not one of its delegates been sick in bed." The absent Virginian was James Monroe, who for himself has left no evidence of such an intention. For North Carolina the vote of Spaight was neutralized by Williamson. Six States against three, sixteen men against seven strove to stop the spread of slavery. Jefferson denounced this outcome all his life. George Wythe and he, as commissioners to codify the laws of Virginia, had provided for gradual emancipation. When, in 1785, the legislature refused to consider the proposal, Jefferson wrote: "We must hope that an overruling Providence is preparing the deliverance of these our suffering brethren." In 1786, narrating the loss of the clause against slavery in the ordinance of 1784, he said: "The voice of a single individual would have prevented this abominable crime; heaven will not always be silent; the friends to the rights of human nature will in the end prevail." The ordinance passed without the 5th clause despite Jefferson's wishes, and was in force for three years. The ordinance was further augmented with the Land Ordinance of 1785, and superseded by the Northwest Ordinance of 1787. A later attempt by Rufus King to prohibit slavery entirely within these lands failed.
Jefferson's reflections on the ordinance
To the friends who visited him in the last period of his life, he delighted to renew these aspirations of his earlier years. In a letter written just 45 days before his death, he refers to the ordinance of 1784, saying: "My sentiments have been forty years before the public: although I shall not live to see them consummated, they will not die with me; but, living or dying, they will ever be in my most fervent prayer."
