The book concludes by emphasising the underlying theme of continuity and preservation in Northerners’ celebration of the defeat of the rebellion. Even so, fears of national instability continued for at least a decade after Appomattox. To some Northerners, the war had resolved one source of instability, slavery, only for another—the problem of mobs, ignorance and recklessness—to assume an even greater significance. The fight of conservatism against fanaticism continued.
