The Missouri state flag contains a field of three stripes in the red, white and blue of the national flag. It also holds two grizzly bears, 24 stars, a helmet and a crescent moon pointing up, towards the heavens.
  
In short, it holds the symbolic history of a new state born out of conflict from new territory. Here is the history of the Missouri state flag.  
 
 Morals — all correct moral laws — derive from the instinct to survive. Moral behavior is 
survival behavior above the individual level.

In 1821, the year of its statehood, Missouri was at the crossroads of a geographic and political revolution.
Part
 of the wild west territory culled from Spanish and French colonial 
rule, this was where the debate over slavery was held in a constant and 
contentious balance: 
Geographically,
 Missouri was at the very juncture where a growing nation had to decide 
if its burgeoning borders would be a land of the free or the enslaved.  
Politically,
 the math of legislative and economic power had carefully balanced the 
number of free states against the number of slave states. This could 
easily be upended if or when Missouri was accepted as a state. 
In 1820, the wheel of fortune turned again when Maine applied for statehood (as a free state) and the Missouri Compromise was reached (making Missouri slave territory).

The
 Compromise was a patchwork attempt to appease both sides as it defined 
the territory on one side of the 36° 30' parallel (what would become 
Kansas) to be free and territory on the other side (Missouri) to be 
slave. The fact that Missouri was a borderland – of politics as well as 
 geography – was evident in the many and often dramatic legislative  
proposals that were put forth prior to and after the Missouri Compromise. 
In 1821, when Missouri again applied for statehood (for the 8th time), it was granted.

Some thirty years later, the Kansas-Nebraska Act of 1854 (the concept of popular sovereignty)
 overrode the Missouri Compromise. It allowed for the settlers in Kansas
 and Nebraska to decide (to vote) for themselves if they would or would 
not allow slavery within their territory. This seems simple enough but it was a political tinderbox that fired such far-reaching discussion as the 1858 Lincoln-Douglas debates in Illinois.
  
In
 short: either you were for a version of self-rule (which made room for 
slavery) or you found the expansion of slavery impossible to condone 
(which gave the federal government the right to override laws allowing 
slavery in the new territories).

| Mr. Dred Scott (Missouri Historical Society) | 
The 
Dred Scott Decision (1857) underscored the chaos and the tragedy of these times. In their decision, the 
Supreme Court ruled that:
 
1. the Missouri Compromise (which prohibited slavery in some of the new territories) was unconstitutional. 
2. African Americans – slave or free – were not citizens (nor eligible for citizenship).
3.
 because African Americans were not citizens, they (including children 
born on free land) had no ability to seek any protection under the law 
(to sue). 
4.
 Slaves were to be treated as physical property under the law. 
Specifically, a law (like the Missouri Compromise) could not free a 
slave from his/ her owner, even if the "slave" was living in "free" 
territory.
In
 practical terms, this meant that if you were free in one territory, you
 might not be free in another territory. Likewise, if you were a slave 
in one  territory but had been living in a "free" territory and had 
raised children in that  territory, your former master could claim you 
and your children – and  you could do nothing about it because you did 
not have any rights as a  citizen.
As
 the West was settled in the boom decades between 1820 and 1860, a 
harvest of political unrest was being planted that eventually would grow
 into the Civil War.
A new flag ...  
After the Civil War and at the turn of the 20th century, the country was taking stock. It was at this time that the Daughters of the American Revolution began to sponsor state flag contests. The Missouri state flag is the result of the 1908 flag contest.
The state flag of Missouri was designed by Mrs. Marie Elizabeth Oliver, the chairperson of the local DAR search committee and the wife of Senator Robert Burett Oliver. 
A second Missouri state flag, one designed by Dr. G. H. Holcomb, had been under consideration but Oliver's design ultimately was chosen. In 1913, the Oliver flag became the official Missouri state flag.  
The
 Missouri state flag consists of three, wide, horizontal, red, white, 
and blue stripes – the colors of the national flag. In the center is the
 Missouri state seal. This juxtaposition underscores the union between 
the state and the nation. Placing the seal at the center of the Missouri
 state flag also emphasizes Missouri's place in the middle of the 
nation. 
Within
 the Missouri state seal there are 24 stars as Missouri is the 24th 
state. The largest star is supposed to represent the fact that Missouri 
became a state after rising above significant challenges. The grizzly 
bears and helmet are symbols representing the strength and fortitude of 
Missouri. 
 
The
 crescent moon on the Missouri state flag can be read two ways: Its two 
points can indicate that Missouri is the second state to "grow" out of 
the new territory (from the Latin, cresare,
 to grow). In traditional heraldry, however, a crescent moon facing up, 
as this one does, generally indicates that this is a branch of a larger 
family. This would indicate Missouri as growing out of the new 
territories as well as being a part of the United States.     
There are two mottoes on the Missouri state flag. One is in English: 
United We Stand. Divided We Fall. Again, this emphasizes the importance of unity. The Latin motto, Salus populi suprema lex esto translates to "Let the welfare of the people be the supreme law."
