Many of the northerners who sympathized with the oppressed blacks in the South never dreamt of having them as their neighbors.

There were, consequently, always two classes of anti-slavery people, those who advocated the abolition of slavery to elevate the blacks to the dignity of citizenship, and those who merely hoped to exterminate the institution because it was an economic evil.[4] The latter generally believed that the blacks constituted an inferior class that could not discharge the duties of citizenship, and when the proposal to incorporate the blacks into the body politic was clearly presented to these agitators their anti-slavery ardor was decidedly dampened.

Unwilling, however, to take the position that a race should be doomed because of personal objections, many of the early anti-slavery group looked toward colonization for a solution of this problem.[5] Some thought of Africa, but since the deportation of a large number of persons who had been brought under the influence of modern civilization seemed cruel, the most popular colonization scheme at first seemed to be that of settling the Negroes on the public lands in the West.
As this region had been lately ceded, however, and no one could determine what use could be made of it by white men, no such policy was generally accepted.
When this territory was ceded to the United States an effort to provide for the government of it finally culminated in the proposed Ordinance of 1784 carrying the provision that slavery should not exist in the Northwest Territory after the year 1800.[6] This measure finally failed to pass and fortunately too, thought some, because, had slavery been given sixteen years of growth on that soil, it might not have been abolished there until the Civil War or it might have caused such a preponderance of slave commonwealths as to make the rebellion successful.

The Ordinance of 1784 was antecedent to the more important Ordinance of 1787, which carried the famous sixth article that neither slavery nor involuntary servitude except as a punishment for crime should exist in that territory.

At first, it was generally deemed feasible to establish Negro colonies on that domain.
