Why the Civil War Was Not About Slavery

Not so long ago, historians wrote about the Civil War as a conflict between the North and South over tariffs. Now we are bombarded with propaganda that the war was between the “good” North and the “evil” South over slavery. 

That’s preposterous. The facts show that the Civil War was not fought to end slavery. 

On the eve of Lincoln’s Inauguration as 16th president, the U.S. Congress was proposing a constitutional amendment to protect slavery. On March 2, 1861 with only Northern states voting, Congress passed the Corwin Amendment to protect slavery. In his First Inaugural Addresson March 4, President Lincoln endorsed the amendment saying, “I have no objection to its being made express and irrevocable.”

The North clearly did not want to go to war to end slavery. It would not have offered to provide constitutional protection for slavery if it were willing to go to war to end it. The South refused to endorse the amendment because returning to the Union meant paying having to pay high tariffs on imports. 

The real issue between the North and South was not slavery. It was economic. The North was willing to preserve slavery permanently, but was not willing to give up the high tariffs and economic policies imposed on the South. For the South, keeping slavery but continuing to pay high tariffs imposed by the federal government was the road to economic disaster. 

The war of 1861 is commonly called the Civil War.  But was it? 

A civil war is a struggle between two or more entities trying to take over the central government. Confederate President Jefferson Davis and General Robert E. Lee certainly were not waging war to take over Washington, D.C. anymore than General George Washington was fighting to take over the government of George III. 

To the contrary, both were fighting to leave those governments. 

Why the South Seceded 

Throughout most of our nation's history, the only sources of federal revenue were excise taxes and tariffs. During the 1850s, tariffs on imported goodscomprised 95 percent of the federal revenue. Southern ports paid 83 percent of tariffs in 1860. Four out of every five dollars -- 80% -- of the tax revenues were spent on Northern public works and industrial subsidies. If Southern states seceded, that revenue would be lost and the federal government would become drastically smaller. With his Emancipation Proclamation, Lincoln did not intend to free slaves but rather to force the South to remain in the Union even if the tariff revenue was collected at gunpoint. 

In May 1860, Congress passed the Morrill Tariff which raised the tariff from about 15% to 37% with increases to 47% within three years. The South, with only 29% of the nation’s population, was paying around 83% of the tariff revenues through its ports in 1860. This protected Northern industrial interests while raising the cost of living and commerce in the South and reducing the trade value of their agricultural exports. 

Of those tax revenues, four out of five dollars -- 80% -- were spent on Northern public works and industrial subsidies at the expense of the South. The federal government was funded through tariffs since there was no income tax. 

Lincoln had been elected on the promise of increasing tariffs. His support came from Northern and Mid-Western businessmen who needed those federal revenues. 

With the election of Lincoln and passage of the Morrill Tariff, Southern leaders in South Carolina and the Gulf States began calling for secession. South Carolina seceded in December 1860 with Mississippi, Florida, Alabama, Georgia, and Louisiana following in January 1861 and Texas in February 1861. 

Lincoln remained true to his promise that he would enforce collection of the tariff. In April 1861, after manipulating the South to fire on the tariff collection facility of Fort Sumter, he issued an order for 75,000 volunteers to descend upon South Carolina to crush the “rebellion.” 

Lincoln gambled that his threat would tamp down secession. Instead, shocked by the Union’s ruthless invasion, the Border States of Virginia, Arkansas, Tennessee and North Carolina seceded in May 1861. 

Why the North Fought the War

The industrial North was rapidly gaining control of the federal government for its own political ambitions to centralize its power. The Northern corporations wanted high tariffs (taxes) on goods produced by the South because it reduced competition with European manufacturers and allowed the North to charge higher prices for often substandard goods. The revenue was used to fund Northern industry, transcontinental railroads, and the creation of national banks to manage it all. This was at the expense of Southern agriculture. Cotton was especially lucrative. 

Essentially the South was becoming agricultural colonies of the North with the industrial revolution made possible through slave labor.

The North fought the war to keep the South from seceding. With the secession of the Southern States, the North lost its largest source of tariff revenues, its source of cotton for mills, a large portion of its markets for manufactured goods, and control of the mouth of the Mississippi. If the South were allowed to leave the Union, the Northern economy would crash and the federal government was at risk of being drastically reduced in size and control. 

In his First Inaugural Address, Lincoln said, “The power confided to me will be used to hold, occupy, and possess the property and places belonging to the Government and to collect the duties and imposts; but beyond what may be necessary for these objects, there will be no invasion, no using of force against or among the people anywhere.” Southerners understood that to mean that, as long Southerners paid the tariff, there would be no Union invasion. 

After the South seceded, Lincoln provoked their firing the first shot at Fort Sumter, blockaded the Confederate coasts and marched Union armies across the South, burning and pillaging and raping and killing – until the Southern states were forcedto rejoin the Union. 

Conclusion 

America is the only nation where politics focus on a centuries-dead slave past.Leftists have used our slave history to cobble together a new proletariat for a Marxist Cultural Revolution with blacks as the oppressed and whites -- especially Southern -- as the oppressors. 

George Orwell in his novel, 1984, wrote, “The most effective way to destroy people is to deny and obliterate their own understanding of their history.” This is what is happening in America. The destruction of the remaining symbols of the Confederacy is how the left is annihilating our memory. Once the older generation dies, the younger ones will have only the left’s version of our history and culture.
