Montana
Officially adopted in 1905, at first glance, the Montana state flag looks like an ad for a nature resort. The current flag is an adaptation of Colonel Harry C. Kessler’s flag, head of the 1st Montana Infantry, created in 1898, to distinguish his troops from other forces during the American-Spanish war.
The seal shows are a miner’s pick and a shovel with the Great Falls of the Missouri River running nearby surrounded by picturesque mountain scenery. A ribbon beneath the mining tools displays the Spanish words “Oro y Plata” (gold and silver), the state motto, and the state’s name “Montana” appears above the seal.
Mississippi
Most state flags have evolved over the year to reflect its residents' current temperament and the ones that haven't are highly controversial topics today. Mississippi’s state flag resembles Georgia’s, except that unlike Georgia, they chose to keep the Confederate battle flag blue-star-adorned cross. It remains the only state flag that continues to bear the tendentious symbol; however, many non-minority Mississippians are pretty adamant about it keeping it.
In 2001, a proposal to remove the Confederate battle flag once and for all was soundly defeated by Mississippi voters, thus the original design remains.
Missouri
In 1820, Missouri was the 24th state to join the Union but for nearly a century after achieving statehood, it did not adopt an official flag. So, when they finally decided on one in 1913, they made it a point to pack it with symbolism. The flag was designed by Marie Elizabeth Watkins Oliver, who was in part, inspired by Missouri's historic coat of arms which displayed a Bald Eagle with olive branches (peace) and arrows (war), a grizzly bear (strength and courage), and a crescent moon (bright future). On top are the words “United We Stand, Divided We Fall.”
The horizontal stripes of red, white, and blue are reminiscent of the state's French heritage, the coat of arms is supported by two additional grizzly bears standing on a scroll inscribed with the words “Salus populi suprema lex esto” which translates to “Let the welfare of the people be the supreme law.” Below the scroll are the Roman numerals for 1820 all circled with a band of 24 stars denoting Missouri’s induction into the union.
Nebraska
Nebraska is known as being one of the last states in the U.S. to officially adopt a state flag, which it finally did in 1963. Better late than never. To be fair, for decades, the good ol' state seal on a blue background, was unofficially recognized as the state flag, as was common practice in many states back in the 19th century.
The Nebraska state seal pictures a blacksmith using a hammer and anvil symbolizing the mechanic arts, and wheat sheaves, stalks of corn, and a settler's cabin, representing agriculture. In the background, there's a steamboat on the Missouri River, and a train on the transcontinental railroad headed west toward the Rockies. The banner above the landscape bears the state motto: “Equality Before the Law.” Circling the seal are the words “Great Seal of the State of Nebraska” and “March 1st, 1867,” the year Nebraska was admitted into the Union.
Nevada
The state of Nevada has had several state flags throughout its history but eventually settled for their current (and much more subtle) flag. On what is described as a 'cobalt blue' background, are several of the state's symbols: a wreath consisted of two crossed sprays of sagebrush (the state flower), with a silver star (the state metal) at the center, and the word “Nevada” positioned underneath the star in yellow.
A ribbon above the wreath contains the words “Battle Born” in recognition of the fact that Nevada gained its statehood during the Civil War.
