Mottos play an important role in our lives. Nations, states, companies, and organizations of all kinds choose them and uphold them with utmost care: they encapsulate the beliefs, values, and ideas that guide them. Let's have a look at some of our favorite American mottos, their meanings, and the history behind them!

This We'll Defend has been the motto of the United States Army since the days of the Revolutionary War, when it was still the Continental Army. It manifests the unwavering will to defend and preserve the interests of the nation above everything else. Today, it can be seen on the official US Army flag and on the emblem of the Department of the Army.

Latin | ā-ˌplu̇r-i-bu̇s-ˈü-nu̇m | Out of Many, One
While probably second to In God We Trust in popularity contests, E Pluribus Unum is still a major motto of the United States of America, appearing on the Great Seal. It perfectly encapsulates the sentiment behind the creation of the United States: many states coming together to form a strong and free Union. Out of many, one.

Latin | sem-pər-fə-ˈdā-ləs | Always Faithful/Loyal
Usually shortened to Semper Fi, this is the motto of choice for the United States Marine Corps and many other military and civilian organizations. It embodies the Marines' values of honor, courage, and commitment; as well as their unyielding loyalty towards each other and the people they serve.

The Boy Scouts of America is one of the largest scouting organizations in the world, with close to 3,000,000 active members. It's been part of the lives and youth memories of many American citizens. Be Prepared finds its roots in the 1908 book Scouting for Boys by the British Army Officer Robert Baden-Powell.

Latin | sem-pər-pə-ˈrä-təs | Always Ready
No one knows for certain how the words Semper Paratus came to be the motto of the United States Coast Guard, but it was Captain Francis Saltus Van Boskerck who immortalized them when he penned the 1928 march of the same name (now, naturally, the official march of the Coast Guard).
Live free or die: New Hampshire

General John Stark, New Hampshire´s most famous American Revolution hero, wrote Live Free or Die: Death is not the worst of Evils as a toast after the war. His words reflect the ideals of liberty that flourished during both the French Revolution and the American War of Independence.
Live Free or Die is now the official state motto of New Hampshire, and can also be found on the state´s license plates.
Ad Astra per Aspera: Kansas

Latin | ad-ˈa-strə-ˌpər-ˈa-spə-rə | To the Stars through Adversity
Different variations of the phrase Ad Astra per Aspera have been frequently used by a large number of organizations. This is because it represents a noble sentiment: that all hardships will eventually pass, and that progress comes through enduring them.
Ad Astra per Aspera is now the state motto of Kansas.
Semper Supra: US Space Force

Latin | sem-pər-sü-prə | Always Above
Fitting for the United States Space Force, Semper Supra (Always Above) has been their motto and the name of their official march since 2022. The motto was coined by US Air Force Senior Airman Daniel Sanchez, who chose it after researching the mottos of other branches of the military and deciding that Semper Supra and its translation were easy to say and memorize.
Labor Omnia Vincit: Oklahoma

Latin | lä-ˌbȯr-ˌȯm-nē-ˌä-ˈwiŋ-kit | Work Conquers All
Close in sentiment to Ad Astra per Aspera, this phrase emphasizes that anything can be achieved by hard work and dedication. It has a long history, dating back to a poem by Virgil during Caesar's rule in Ancient Rome. Labor Omnia Vincit has been used extensively as a slogan, and it serves as the motto of the state of Oklahoma.
For the Benefit of All: NASA

While NASA has used Ad Astra per Aspera as a slogan on different occasions, For the Benefit of All is its official motto. This phrase encapsulates the spirit of NASA's mission, which is to explore the secrets of the universe for the benefit of all humanity.

The Federal Bureau of Investigation is an organization that takes pride in holding its members to the highest standards of personal character. That´s why they chose Fidelity, Bravery, Integrity as their motto, to showcase the values they prize the most. Coincidentally, these three terms can also be abbreviated as the initialism FBI.
Friendship: Texas

A deceptively simple motto with a storied background, Friendship is a rough translation of the name of Texas itself. Texas or Tejas was the Spanish transcription of the name of a local native tribe, whose name meant "friends" or "allies." In time, Texas became the name of the state, and its original meaning of Friendship survived as its official motto.
In God We Trust

Adopted by Congress in 1956, In God We Trust became the official motto of the United States, replacing E Pluribus Unum, which had been in use since its appearance in the design of the Great Seal of the United States. It was received with almost unanimous approval by the general population, and it remains one of the most popular mottos in America. It's on display on several government buildings and, of course, printed on American currency.
