The second Continental Congress had deliberated fourteen months before declaring American independence in 1776. To produce the United States Constitution and put the new government into operation required nearly two years. In contrast, the Confederate States of America organized itself, drafted a constitution, and set up shop in Montgomery, Alabama, within three months of Lincoln’s election. The South moved so swiftly because, in seeming paradox, secession proceeded on a state-by-state basis rather than by collective action.
