Missouri, also known as the “Show-Me State,” is a land of incredibly geographical diversity and historical significance. It also lies in the heart of the United States and is an important part of the country’s center. Missouri consists of a unique blend of landscapes, culture, and history.

When Did Missouri Officially Join the US?

The admission of Missouri as the 24th state in the United States was a pivotal moment in the country’s history. This is because it was marked by both political controversy and territorial expansion. The events leading up to Missouri’s statehood, including the Missouri Compromise of 1820, played a significant role in shaping the nation’s stance on slavery.

Background Leading to Missouri’s Admission

To understand the context of Missouri’s admission, we must first look back to the early 19th century when the United States was rapidly expanding westward. The Louisiana Purchase of 1803 had just doubled the size of the nation. Thus, new territories were coming out from this new land.

The Issue of Slavery

As territories organized and new states joined the United States, there was still the question of slavery that loomed nationally. At this time, the nation was sharply divided along sectional lines, with the northern states increasingly opposing the expansion of slavery into new territories.

The Missouri Compromise of 1820

The Missouri Compromise was a pivotal piece of legislation that sought to address the issue of slavery in the context of Missouri’s admission as a state.

Missouri initially sought admission to the Union as a slave state. However, the Northern states resisted this because they opposed the expansion of slavery. At that time, there was an equal number of slave and free states in the Union, and the admission of Missouri as a slave state would have threatened this delicate balance.

To maintain this balance, Maine, which was then part of Massachusetts, was admitted to the Union as a free state in 1820. This effectively countered Missouri’s admission as a slave state. Thus, it preserved the equilibrium between slave and free states in the Union.

One of the most notable aspects of the Missouri Compromise was the establishment of a line. This was the 36°30′ parallel that would delineate where slavery could exist in future territories. This meant that south of this line, slavery would exist, while north of it, it wouldn’t.

However, the Missouri Compromise was only a temporary solution to the issue of slavery expansion. This is because the situation was very delicate and further compromises and negotiations would happen as new territories joined in.

The Significance of Missouri’s Admission

Missouri’s admission as a state and the accompanying Missouri Compromise legislation were significant for several reasons.

By admitting Missouri as a slave state and simultaneously bringing in Maine as a free state, the compromise temporarily preserved the balance of power between slave and free states in the Senate. This was essential to prevent either side from gaining a significant advantage in legislative matters related to slavery.

The Missouri Compromise also highlighted the deep-seated tensions between the North and the South over the issue of slavery. Unfortunately these tensions would continue to simmer and ultimately erupt during the Civil War several decades later.

The admission of Missouri also demonstrated the impact of the ongoing westward expansion of the United States. As the nation expanded, the question of whether newly acquired territories would allow slavery became an increasingly contentious issue.

Therefore, the Missouri Compromise set a precedent for using legislative compromises to address disputes. It showed that the nation could, at times, find middle ground on highly divisive issues, even if temporarily.

Which States Border Missouri?

Missouri has several neighboring states including Iowa, Arkansas, Kansas, Illinois and Tennessee.

Missouri’s unique geographical location in the American Midwest places it in close proximity to a diverse range of states. These neighboring states have played a significant role in Missouri’s history, culture, and economic interactions.


To the north of Missouri, Iowa shares a significant portion of its northern border with the state. The Mississippi River forms a natural boundary between the two states. Iowa is famous for its fertile farmland, rolling hills, and the Mississippi River Valley. The region along the border has several picturesque river towns and scenic bluffs. Both Missouri and Iowa have historically connected by trade along the Mississippi River.


Missouri shares its eastern border with Illinois, and thus, the Mississippi River once again serves as a natural dividing line. The two states have a rich history, particularly shared during the westward expansion and the American Civil War. Cities like St. Louis in Missouri and East St. Louis in Illinois are part of the same metropolitan area and share economic ties.


To the southeast, Missouri shares its border with Kentucky, separated by the Mississippi River along its southeastern edge. The confluence of the Mississippi and Ohio Rivers in this region has historical significance and has played a crucial role in transportation and trade. Kentucky is famous for its horse racing, bourbon production, and historical sites.


The southwestern border of the state is with Tennessee, and once again, the Mississippi River creates the boundary. This region is part of the Mississippi Delta, characterised by fertile soil and a unique cultural heritage. Tennessee is famous for its music, including country, blues, and rock ‘n’ roll, and the city of Memphis, with its vibrant music scene, is located just across the river.


To the south of Missouri, the state of Arkansas has a diverse landscape that transitions from the Ozark Mountains in the north to the fertile lowlands of the Mississippi Delta in the south. The Mississippi River again separates the two states, and this region has a shared history tied to agriculture and river trade.


Missouri’s southwestern border is with Oklahoma, and this region marks the transition from the Midwest to the Great Plains. Oklahoma is famous for its Native American heritage, cowboy culture, and vast open spaces. The shared border also has historical significance, especially because of Native American removals from the state like the Trail of Tears.


The state shares its western border with Kansas, and this region played a significant role in American history, particularly during the westward expansion and the American Civil War. The Kansas-Missouri border was a hotspot of conflict during the “Bleeding Kansas” era, as tensions over slavery flared.


The state shares its northwest border with Nebraska. Nebraska is famous for its agriculture, open landscapes, and the Sandhills region.
