The Cotton Gin and Slavery

Leland Johnson is a student of history, religion, politics, and current events. He wishes to respectfully engage readers on those points.

The Cotton Gin


The harvesting and processing of cotton was an extremely labor intensive exercise. The cotton, once harvested by hand, had to be hand-picked free of seeds so that it could be used as a fiber in the manufacturing of clothing. Laborers could only put out about 1 pound of cotton per day. The cotton gin, by comparison, was able to do the work of 50 men prepping an amazing 50 pounds of cotton daily. One would think that this would be a valid reason to release slaves, but the opposite is true. With the new ability to harvest, clean, and export cotton, demand rose and so did the demand for slaves. With countries all across the globe seeking more and more cotton (the South provided 70% of the world's cotton) American Southern plantation owners began clearing fields which in turn demanded more laborers, hence an increase in demand for slaves.

The cotton gin (short for engine) was invented in 1793. Cotton production with slaves jumped from 178,000 bales in 1810 to over 3,841,000 bales in 1860. In direct proportion to the expansion of the cotton industry so to did the slave industry increase. During that same 50 year period the number of slaves in the United States increased from nearly 2 million to over 4 million.

Reasons for the Secession of Southern States

I have often heard people say, both in casual conversation as well as historical narrative, that there were many reasons the Civil War was fought, slavery being only one among them. When it comes up in conversation, and it does in my circles, I like to ask the person making the statement this question:

"Could you tell me some of the other reasons?" The answer I get is always the same.

"It was more to do with states rights." I have a follow up question prepared.

"Which states rights?"

People are usually not able to answer this question, in fact I'd go so far to say I've never heard a reasonable answer to the simple follow up, "which states rights are we talking about?"

Are we talking about the right of the southern states to grow tobacco, cotton, export magnolias? Exactly which rights were being infringed that merited going to war? No, the North did nothing to oppose Southern states from doing business. Now there are some who would disagree, but that disagreement must be buttressed by the fact that the only way Northern policies would interfere with the financial prosperity of the South was by interfering with the institution of slavery.

The invention of Eli Whitney's cotton gin had created an increased ability to harvest cotton, and in turn, an increased need for man power- manpower provided by slaves.

The tale of slavery is a tale of greed at its core. Why didn't plantation owners just hire workers? Why didn't southern politicians work to establish stronger business ties to Great Britain, the main consumer of southern cotton? The South, in fact, believed that Great Britain would come to their aid in the event of a Civil War just to protect their own financial interests.

The cotton gin provided an opportunity for the South to begin the dismantling of slavery. Instead, they used it as a way to further their financial prosperity. They did, after all, own huge mansions and enormous amounts of land. It isn't as if they needed slave labor to survive. They just needed it to survive lavishly.

The Cotton Gin in Use

Slaves labor to operate the device that could've made slavery irrelevant.  Instead, demand for slaves increased as the ability to harvest grew.

It is certainly going too far to that the invention of the cotton gin led to the Civil War. That would be like saying the invention of the automobile led to drunk driving. While there is a definite association it possible to have one without the other. You can have a car and NOT drive while intoxicated. So too the cotton gin could have existed in a slave free South. (It existed elsewhere under slave free conditions) Had the cotton gin not been invented surely something else would've come along to appease those in favor of slavery and further their ambitions. After all, we've argued that the cotton gin actually could have contributed to the elimination of slavery. Slavery began prior to the cotton gin and continued after it. It's misuse is not the reason for the War. So what is? I would like to conclude with a quote from Philip Van Doren's excellent work, The Life and Writings of Abraham Lincoln.

"For seventy-five years historians and political observers of all shades of opinion have been trying to fasten the cause of the Civil War on anything except slavery. They have advanced theories putting the responsibility for the War on the violation of states rights, on widespread economic differences between the North and the South or on the natural conflict between agrarian and industrial interests. All these causes are correct enough. They did help aggravate the situation. They were involved in many of the events leading to battle. The American Civil War was, of course, too complicated a movement to have been precipitated by any single cause. But it is undeniable that underneath all the political and economic moves were the four million enslaved blacks, omnipresent and inescapable, whose bondage was the keystone of the Southern economy was equally a the keystone of economy of the North, and an affront to the moral sense of the world. The men who fought the Civil War realized this; they should be given some credit for knowing their own minds. Their rallying cry was "Preserve the Union!" but although they did not fight merely to free the slaves, they knew that there would have been no war if there had been no slaves." (emphasis mine)

It is my belief that perpetuating the idea that the Civil War was fought over states rights is a miscarriage of understanding. In one sense we might even agree and say, "yes it was a war over the rights of the states- their right to own slaves."

Several legal and diplomatic attempts were made to reduce, and curtail slavery with the eventual goal of complete abolition. Discussion of these efforts are subjects for future articles. However, I would like to close by saying that in every instance these efforts were thwarted by political maneuvering, back room intrigues, bribes and every form of coercion and murder available to human imagination. The only thing that would end slavery would be war.

Ronald, I just re-read one of your earlier comments and have to point out what a good point you make- The idea of pro-slavery elements disassociating their loss from the evil of slavery makes perfect sense and provides the impetus to continue touting the glories of the "cause." D'nesh D'souza pointed out that it wasn't really a "Southern" issue as much as it was a Democrat/Republican issue. He asserts that the democrats of that time, both Northern and Southern, were pro slavery while the emerging Republican party was in opposition to slavery. I've researched his statements and can find no fault with them. What are your thoughts?

Thanks MsDora. Your thoughtful commentary is always appreciated. I think this topic of study is a lifelong study. There are more stories to be told than can be heard by one person, but I want to hear as many as I can.

Between you, Leland and Ron Franklin, I have received many interesting lessons on the value of the slaves and their labor. I appreciate the research and presentation on these facts. Never knew until now the impact of the cotton gin.

Once during my high school days, the cotton crop was more than the laborers could handle, and the students were sent to help out for a day. Your article reminded me.

Leland Johnson (author) from Midland MI on June 12, 2018:

wow- that adds up. Thank you Ronald. I am interested in exploring this topic more to debunk the idea that the War was about states rights. I've often asked the question, "if the War was just about states rights then why have the 13th amendment at all? Doesn't that prove the war was about slavery?" Thanks for your response.

Ronald E Franklin from Mechanicsburg, PA on June 12, 2018:

Starting immediately after the war and continuing until now, many white southerners were very concerned to maintain the honor of those who fought in the Confederate cause. Therefore, the "Lost Cause" had to be disassociated from the evil of slavery. Alexander Stephens, for example, was very frank before the war that slavery was the "cornerstone" of the new Confederacy. But when the war ended and the Confederacy became only a memory, Stephens maintained that slavery was just a "minor issue" in a conflict that was really about different views of government (in other words, states rights).

Leland Johnson (author) from Midland MI on June 11, 2018:

Ronald- thank you for providing that excellent information. Ronald, why do you think some people feel compelled to portray slavery as merely a component of the Civil War rather than the cause?

Ronald E Franklin from Mechanicsburg, PA on June 11, 2018:

Good analysis. Many historians believe that until the advent of the cotton gin slavery was in the process of dying out in the South, as it did in the North, because it wasn't profitable enough to sustain itself. As you say, the cotton gin changed all that, and slavery became a fundamental aspect of the Southern economy. Confederate president Jefferson Davis himself noted that with slaves accounting for about $3 billion in economic value, Northern abolitionist sentiment threatened to wreck the South financially by “rendering the property in slaves so insecure as to be comparatively worthless.” That, as Davis, Confederate VP Alexander Stephens, and the seceding states themselves not only admitted, but proudly proclaimed, was the reason the South was willing to go to war to maintain the prosperity the cotton gin brought about.
