"We of the South will not, cannot, surrender our institutions. To maintain the existing relations between the two races, inhabiting that section of the Union, is indispensable to the peace and happiness of both. …There is and always has been in an advanced stage of wealth and civilization, a conflict between labor and capital. The condition of society in the South exempts us from the disorders and dangers resulting from this conflict; and which explains why it is that the political condition of the slaveholding States has been so much more stable and quiet than that of the North." - Excerpt from John C.
