Missouri – Kansas Border Events That Happened Before the Civil War

The Kansas-Missouri Border War, also known as Bleeding Kansas, was a series of violent civil confrontations between the people of Kansas and Missouri that occurred immediately after the signing of the Kansas-Nebraska Act in 1854. The border war began seven years before the Civil War officially began and continued into the war.

Did The Civil War Start Along the Missouri and Kansas Border? 

The Missouri Kansas border War took place from about 1855 and 1859 and it known for it’s violent guerrilla warfare between pro-slavery and anti-slavery forces (Bleeding Kansas) that many historian agree significantly shaped American politics and contributed to the coming of the Civil War.

Sacking of Lawrence

It is believed by many historians that the beginning of the Civil War was sparked when Missourians and Kansans fought over whether Kansas would be a free state or a slave state.

One of the most famous events in this feud was the sacking of Lawrence, which occurred on May 21, 1856.

The sacking of Lawrence is when pro-slavery settlers led by Douglas L Jones, a sheriff of Douglas County ransacked Lawrence Kansas, a town that was founded by settlers from Massachusetts, hoping to make Kansas a free state. color

The Pottawatomie Massacre

The Pottawatomie massacre was another pivotal point in this conflict. John Brown and other abolitionist settlers killed five pro-slavery settlers in front of their families in Franklin County between May 25-26 of 1856. This was 5 years before the start of the Civil War, illustrating how the Civil War was a long-in-the-making conflict. 

9 Facts You May Not Know About Missouri During The Civil War

Missouri During The Civil War

1. Was Missouri a Confederate State?

Missouri was claimed by both the Union and the Confederacy. As I shared above, it had two rival state governments, and sent representatives to both the United States Congress and the Confederate Congress.

In Missouri over 110,000 men enlisted in the Union Army, while over 90,000 men enlisted in the Confederate Army. These Confederate men however would go on to enlist in other states such as Arkansas and Texas. This included over 60% of Missouri’s fighting-age men.

2. Over 1,200 Civil War battles were fought in Missouri

Missouri Civil War Battles

From 1861 to 1865 Missouri saw over 1,200 battles of varying degrees. In the first year of the war, 1861, 42% of all battles and casualties were on Missouri soil

Some of the biggest battles during the Civil War that happened in Missouri were fought in the Kansas City area.

For those of us living in Kansas City, you may have driven past Jacob L. Loose Park. What you may not know is that the park is the site of the Battle of Westport. The battle was fought on October 23rd, 1864, where Major General Samuel L. Curtis of the Union Army and his troops defeated the forces of Major General Sterling Price of the Confederates troops. 

The Battle of Lexington, Where Oliver Anderson’s house was the center point of a three-day battle where to this day you can still see bullet holes and Cannonball holes in its walls.

The Battle of Wilson’s Creek was the first major battle fought west of the Mississippi in the Civil War. It is also known as the Battle of Oak Hills And was fought on August 10th, 1861.

3. Missouri was the 3rd most fought-over state in the Civil War

Missouri was the third-most fought-over state of the Civil War, after Virginia and Tennessee.

The struggle for Missouri was one of the most prolonged and violent conflicts of nineteenth-century America according to essentialcivilwarcurriculum.com, and extended far beyond the boundaries of the Civil War.

It is widely accepted that events in Missouri prior to 1861 triggered the national debate over the westward expansion of slavery.

Missouri was a contested border state populated by both Union and Confederate sympathizers.

Thus, Missouri was claimed by both the Union and the Confederacy. Each side wanted to have Missouri for their fight.

Many Missouri citizens wanted Missouri to be a free state, while others advocated for it to be a slave state. Many people do not realize that certain fought-over States had men enlist on both sides of the war.

Out of the eight Upper South States that had not seceded, Missouri was the most populous state west of the Mississippi, making it a prime spot for people on both sides to fight for Missouri to join their side of the war. 

4. Missouri had over 114,000 slaves before the Civil War

According to the 1860 census, Missouri had a free population of 1,067,081 and a slave population of 114,931. Surprisingly, this number is not relatively small compared to the other Southern States, even the larger ones.

In 1860 Texas had a reported 182,566 slaves which was roughly 78,000 more than Missouri. With that said, when you take into account that Texas’s population was 602,432, it turns out that per capita, Missouri and Texas had a similar number of slaves.

While most people think of a slave’s job to be cotton-picking, that was primarily in the Deep South. In Missouri, the majority of slaves were field hands on farms along the fertile valleys of the Missouri and Mississippi Rivers. Despite the difference in work, however, by all accounts, the treatment of slaves in Missouri was no better than in southern states such as Texas and Alabama. 

5. Missouri Men Who Fought in the Civil War

A huge number of Missouri men fought in the Civil War. It is estimated that over 109,000 men enlisted and fought for the Union and at least 30,000 Missouri men fought for the Confederacy. This represents almost 60 percent of men of military age fighting in the Civil War and places Missouri first among the states in proportion to population.

6. An estimated 14,000 Union soldiers from Missouri were killed during the Civil War.

While not all 14,000 of them died specifically in Missouri, all of them were Missouri men that joined the union.

Thousands more Missouri men were wounded.

7. Missouri men who joined the Confederacy have an Unknown Death Count

The Civil War was the bloodiest war in American history, with a recorded 360,222 soldiers on the Union side, and 280,000 on the side of the Confederates.

Because Missourians who enlisted in different states, as well as less record-keeping on The Confederate side, there is no known death count for confederate soldiers from Missouri.

8. The secession of Missouri from the Union

During the American Civil War, the secession of Missouri from the Union was controversial because of the state’s disputed status. Missouri was claimed by both the Union and the Confederacy, had two rival state governments, and sent representatives to both the United States Congress and the Confederate Congress.

9. Frank & Jesse James Fought in the Civil War in the Quantrill Raiders

Quantrill’s Raiders were the best-known of the pro-Confederate partisan guerrillas (also known as “bushwhackers”) who fought in the American Civil War. Their leader was William Quantrill and they included Jesse James and his brother Frank.

William Clarke Quantrill is most famous for having led a raid on the Unionist town of Lawrence, Kansas, in August 1863.

  • March 2, 1820 The Missouri Compromise was passed into law in and regulated slavery in the western states. The Missouri Compromise consisted of three large parts: 1) Missouri entered the Union as a slave state, 2) Maine entered as a free state, and 3) the 36’30” line was established as the dividing line for slavery for the remainder of the Louisiana Territory. It is considered the beginning of what led to the American Civil War.

For a full American Civil War timeline, I really like this one from the National Park Services.

While it may seem like a long time ago, spanning 1861-to 1864, the Civil War was a relatively recent event in history. During the Civil War, the people of Missouri had access to many everyday items we still use today, such as batteries which were invented in 1800, Microphones which were invented in 1827, and even early refrigerators which used ice to keep things cool.

This being said, the Civil War was a terrible time for people to live in. We have to recognize the great sacrifice that these men made by fighting for the rights of African American slaves to be freed.

These are men who fought for the right of all men of all races to be free, and to this day we still see the effects of what they accomplished everywhere we look.

American Civil War movies that Include Missouri

It also might be of interest to check out some of the best American Civil War movies that include Missouri:

Ride with the Devil (1999)

Directed by Ang Lee and based on Daniel Woodrell’s novel, Woe to Live On, Ride with the Devil focused on the border state wars of Missouri and Kansas. It is centered around the Antebellum period before the war, including with the Bleeding of Kansas and the famed Missouri Compromise. It shows how neighbors slaughtered neighbors based on political persuasions and the guerrilla warfare between Americans.

By joining the Bushwhackers (Confederate sympathizers) they fought as insurgents against their Jayhawk neighbors (Union troops). The film’s central hero of Jake Rodel (Tobey Maguire) isn’t even an American; he’s a German immigrant who traveled with his father as a boy to Missouri. However, his best friend is Jack Bull Chiles (Skeet Ulrich), a man from a family with gentry pretensions, albeit only George Clyde’s (Simon Baker) family is rich enough to own slaves—including Daniel Holt (Jeffrey Wright). Ergo, Jake must be a Bushwhacker.
