10 interesting facts about Missouri
1. The first ready-made pancake mix came from Missouri
In 1888, newspaper editor Chris L. Rutt and his friend Charles G. Underwood bought a small flour mill in St. Joseph, Missouri. To sell their extra flour, they developed a self-rising pancake flour in 1888 to 1889. It was later described as the first ready-mix cooking product.

The product became famous as Aunt Jemima. In 2021, PepsiCo replaced that name with Pearl Milling Company, the name of the original St. Joseph business.
2. Missouri does not mean “muddy water”
Many people believe Missouri means “muddy water”, but that is not correct. The state is named after the Missouri River, which took its name from the Missouria, a Siouan-language tribe. The name, as adapted by French colonists, means roughly “one who has dugout canoes”.
3. There is no single way to pronounce Missouri
Residents do not agree on one pronunciation. The two most common versions are “mih-ZUR-ee” and “mih-ZUR-uh”, and many people switch between them depending on the situation. Other regional variants also exist.
4. The French were the first Europeans in the region
French explorers Jacques Marquette and Louis Jolliet travelled down the Mississippi in 1673 and passed the region. French-Canadian settlers followed, and the French founded Sainte Genevieve in the 18th century.
5. Missouri was a divided state in the Civil War
When the Civil War began in 1861, pro-Southern Governor Claiborne F. Jackson sought Confederate weapons and mobilised the state militia. A separate state convention had voted against leaving the Union.
After Jackson and his allies fled Jefferson City in June 1861, the convention installed Hamilton Gamble as governor, and President Abraham Lincoln’s government recognised it. Missourians ended up fighting on both sides.
6. Mark Twain was born in Missouri
Samuel Langhorne Clemens, known as Mark Twain, was born on 30 November 1835 in Florida, Missouri. His family moved to Hannibal, a town on the Mississippi, when he was four.
Hannibal inspired the fictional town of St. Petersburg in The Adventures of Tom Sawyer and Adventures of Huckleberry Finn. Twain also worked as a Mississippi riverboat pilot until the Civil War stopped river traffic in 1861, an experience he described in Life on the Mississippi (1883).
7. The deadliest tornado in US history began in Missouri
On 18 March 1925, the Tri-State Tornado touched down in Shannon County, Missouri, and moved through Illinois and Indiana. It killed 695 people, including 12 in Missouri, and injured more than 2,000.
It remains the deadliest tornado in US history. Its path is usually given as 219 miles (about 352 km), although later research suggests it may have been longer.
8. Missouri changed hands several times before statehood
The region passed between France and Spain in the colonial era before the United States bought it in the 1803 Louisiana Purchase. Missouri entered the Union as a slave state under the Missouri Compromise of 1820.
9. St. Louis hosted the first Olympics outside Europe
The 1904 Summer Olympics were held in St. Louis from 1 July to 23 November 1904, alongside the Louisiana Purchase Exposition, a World’s Fair. They were the first Olympics held outside Europe.
The Games had first been awarded to Chicago but were moved to St. Louis in 1903. Travel was difficult, so only about 69 to 74 of the roughly 650 athletes came from outside North America.
10. Kansas City, not St. Louis, is the largest city
St. Louis is the best-known city in Missouri thanks to the 1904 World’s Fair and Olympics, but Kansas City is the largest by population. St. Louis is also unusual because it is an independent city that is not part of any county.
Other Missouri nicknames
Besides the Show Me State, Missouri is also called the Cave State and the Mother of the West. The Show Me State nickname is unofficial, but it is the one most people know and the one you will see most often.
