In the draft riots which occurred there in 1863, one of the aims of the mobs was to assassinate Negroes and to destroy their property.

They burned the Colored Orphan Asylum of that city and hanged Negroes to lamp-posts.
The situation in parts of New England was not much better.

For fear of the evils of an increasing population of free persons of color the people of Canaan, New Hampshire, broke up the Noyes Academy because it decided to admit Negro students, thinking that many of the race might thereby be encouraged to come to that State.[25] When Prudence Crandall established in Canterbury, Connecticut, an academy to which she decided to admit Negroes, the mayor, selectmen and citizens of the city protested, and when their protests failed to deter this heroine, they induced the legislature to enact a special law covering the case and invoked the measure to have Prudence Crandall imprisoned because she would not desist.[26] This very law and the arguments upholding it justified the drastic measure on the ground that an increase in the colored population would be an injury to the people of that State.
In the new commonwealths formed out of western territory, there was the same fear as to Negro domination and consequently there followed the wave of legislation intended in some cases not only to withhold from the Negro settlers the exercise of the rights of citizenship but to discourage and even to prevent them from coming into their territory.[27] The question as to what should be done with the Negro was early an issue in Ohio.

It came up in the constitutional convention of 1803, and provoked some discussion, but that body considered it sufficient to settle the matter for the time being by merely leaving the Negroes, Indians and foreigners out of the pale of the newly organized body politic by conveniently incorporating the word white throughout the constitution.[28] It was soon evident, however, that the matter had not been settled, and the legislature of 1804 had to give serious consideration to the immigration of Negroes into that State.
It was, therefore, enacted that no Negro or mulatto should remain there permanently, unless he could furnish a certificate of freedom issued by some court, that all Negroes in that commonwealth should be registered before the following June, and that no man should employ a Negro who failed to comply with these conditions.

Should one be detected in hiring, harboring or hindering the capture of a fugitive black, he was liable to a fine of $50 and his master could recover pay for the service of his slave to the amount of fifty cents a day.[29] As this legislature did not meet the demands of those who desired further to discourage Negro immigration, the Legislature of 1807 was induced to enact a law to the effect that no Negro should be permitted to settle in Ohio, unless he could within 20 days give a bond to the amount of $500 for his good behavior and assurance that he would not become a public charge.
This measure provided also for raising the fine for concealing a fugitive from $50 to $100, one half of which should go to the person upon the testimony of whom the conviction should be secured.[30] Negro evidence in a case to which a white was a party was declared illegal.
