Any people anywhere, being inclined and having the power, have the right to rise up and shake off the existing government, and form a new one that suits them better. This is a most valuable, a most sacred right -a right which we hope and believe is to liberate the world. Nor is this right confined to cases in which the whole people of an existing government may choose to exercise it. Any portion of such people, that can, may revolutionize, and make their own of so much of the territory as they inhabit.
-Abraham Lincoln, 1848
The above mentioned view was a common one amongst many Northerners in 1860 and had been for some time. Indeed, the first time secession became a topic of debate amongst US citizens occurred after Jefferson won the 1801 election, spurring New England Federalists to begin the discussion. These talks became very serious during the War of 1812, a conflict that was devastating to the New England economy and lead by a Southern president. DiLorenzo notes:
More than a half century before the first shots were fired at Fort Sumter, three serious secession attempts were orchestrated by the New England Federalists, who believed that the policies of the Jefferson and Madison administrations (1801-1817), especially the 1803 Louisiana Purchase, the national trade embargo of 1807 and the War of 1812, were so disproportionally harmful to New England that they justified disunion. The New England Federalists, and the New England public, debated the wisdom of secession for fourteen years, but never was the inherent right of secession questioned.
The New England secessionists were convinced that, with the election of Jefferson, the federal government "had fallen into the hands of infidel, anti-commercial, anti-New England Southerners," and they believed that there was a conspiracy among the "Virginia faction" to "govern and depress New England," in the words of Stephen Higgenson.
The War of 1812 also outraged the New Englanders and added more fuel to the secessionist fire. They feared that another war with England would annihilate their commerce and also feared being taxed into poverty. Massachusetts refused to send troops to the war, effectively seceding from the Union temporarily. On August 24, 1813, the British captured Washington, DC and New England was in rebellion. The governor of Massachusetts announced that the federal government had failed to live up to the terms of the Constitution. The state legislature agreed and issued a decree that the Constitution "must be supplanted."
Indeed, prior to Fort Sumter than was talk amongst several Northern states of possibly seceding from the Union with the Southern states, or forming a third nation:
Prior to Fort Sumter there was widespread sentiment in the North in favor of allowing the Southern states to peacefully secede. This sentiment was so pervasive, in fact, that there were called the "middle states" -New York, New Jersey, Pennsylvania, Delaware and Maryland. These states, which accounted for more than 40 percent of the country's gross national product, contained three types of secessionists: those who wanted to join the Southern Confederacy, those who wished to form their own "Central Confederacy", and those who simply preferred to allow the South to go in peace rather than essentially destroying the Union by holding it together by military force. One or the other of these secession movements had the support of the Democratic Party in every one of these states, and the cities of Baltimore, New York, and Philadelphia were hotbeds of secessionism. New Jersey had the largest secession movement, followed by New York City and New York State's Hudson Valley region.
Secessionist sentiments was strong not only in border states like Maryland in 1860 but also in New York, Delaware, parts of Pennsylvania, and especially New Jersey. Fernando Wood, the mayor of New York City, wanted the city to secede from both the state of New York and the United States and become a free-trade zone. The state Democratic Party held a convention on January 31, 1861, to address the secession crisis and issued several resolutions condemning the use of military force to keep the Southern states in the Union...
Horatio Seymour, a former governor who would be elected to that office again during the war, supported the idea of a Central Confederacy. "The middle states would be amply justified," he said, "before the world to posterity in casting their lot with their more southern brethren." Like most other Democrats, Seymour believed that using force to hold the Union together perverted the very idea of a Union designed to preserve liberty. "Consent" at the barrel of a gun was viewed by these men as sheer absurdity.
Of all the mistakes the South made their greatest may well have been firing the first shot at Fort Sumter. Lincoln was quick to use the incident to turn public opinion against the South. As the war waged on and it became increasingly unpopular Lincoln would nationalize the telegraphs, shutdown nearly 200 newspapers and jail nearly 20,000 political prisoners in the North alone. At times anarchy would completely carry the day as the New York Draft Riots show.
So what does the loss of secession mean in practical terms? DiLorenzo makes a compelling observation:
The federal government will never check it's own power. That is the whole reason for federalism and the reason the founding fathers adopted a federal system of government. There is no check at all on the federal government unless state sovereignty exists, and state sovereignty is itself meaningless without the right of secession. Thus Lincoln's war, by destroying the right of secession, also destroyed the last check on the potentially tyrannical powers of the central state.
