I think every U.S. state has a motto. Most are not that memorable. My favorite, far and away, is New Hampshire's:

LIVE FREE OR DIE

Powerline has some background on this bold declaration.

It comes from a quote by New Hampshire's greatest Revolutionary War hero, Gen. John Stark. Stark reportedly gave a toast in 1809, when poor health led him to decline an invitation to a reunion of veterans of the 1777 Battle of Bennington: "Live free or die; death is not the worst of evils." . . . General Stark had a way with words. Before leading his troops to victory in the battle of Bennington, which set up the decisive defeat of the British at Saratoga, he told his men, "Tonight, the American flag floats over yonder hill, or Molly Stark sleeps a widow!"

That motto is an in-your-face assertion of liberty in the face of tyranny; the essence of Revolutionary republicanism in four words.

Some other great state mottos:

LIBERTY AND INDEPENDENCE Delaware
STATE SOVEREIGNTY, NATIONAL UNION Illinois
OUR LIBERTIES WE PRIZE AND OUR RIGHTS WE WILL MAINTAIN Iowa
EQUALITY BEFORE THE LAW Nebraska
VIRTUE, LIBERTY, AND INDEPENDENCE Pennsylvania
SIC SEMPER TYRANNIS (Thus Always to Tyrants, i.e., Death to Tyrants) Virginia
QUI TRANSTULIT SUSTINET (He Who Transplanted Sustains) Connecticut

Powerline has this picture of Tehran University students, demonstrating against the regime and on behalf of imprisoned fellow students, with a sign reading LIVE FREE OR DIE.

Once more we face threat from tyrants. This time from those who would impose Islam. LIVE FREE OR DIE.
