In his message to Congress on 29 April 1861, President Jefferson Davis cited the Northern threat to the South’s labor system as a cause of withdrawal from political union with the North. The murderous raid of John Brown in 1859 had convinced the South of the North’s violent intentions, which were supported by influential and wealthy men.

Indispensable African Slaves
“As soon . . . as the Northern States that prohibited African slavery within their limits had reached a number sufficient to give their representation a controlling voice in the Congress, a persistent and organized system of hostile measures against the rights of the owners of slaves in the Southern States was inaugurated and gradually extended. A continuous series of measures was devised and prosecuted for the purpose of rendering insecure the tenure of property in slaves . . .
Senators and Representatives were sent to the common councils of the nation, whose chief title to this distinction consisted in the display of a spirit of ultra-fanaticism, and whose business was . . . to awaken the bitterest hatred against the citizens of sister States, by violent denunciation of their institutions; the transaction of public affairs was impeded by repeated efforts to usurp powers not delegated by the Constitution, for the purpose of . . . reducing those States which held slaves to a condition of inferiority.
In the meantime, the African slaves had augmented in number from about 600,000, at the date of the adoption of the constitutional compact, to upward of 4,000,000. In moral and social condition they had been elevated from brutal savages into docile, intelligent and civilized agricultural laborers, and supplied not only with bodily comforts but with careful religious instruction.
Under the supervision of a superior race, their labor had been so directed as not only to allow a gradual and marked amelioration of their own condition, but to convert hundreds of thousands of square miles of the wilderness into cultivated lands covered with a prosperous people; towns and cities had sprung into existence, and had rapidly increased in wealth and population under the social system of the South . . . and the productions of cotton, sugar, and tobacco, for the full development and continuance of which the labor of African slaves was and is indispensable, had swollen to an amount which formed nearly three-fourths of the exports of the whole United States and had become absolutely necessary to the wants of civilized man.
With interests of such overwhelming magnitude imperiled, the people of the Southern States were driven by the conduct of the North to the adoption of some course of action to avert the danger with which they were openly menaced.”
