So much for “the shot heard ‘round the world.”

The nation recently celebrated a quarter-millennium since the first battles of the American Revolution, fought at Lexington and Concord on April 19, 1775. But, as a recent Wall Street Journal column noted, you wouldn’t know it from talking to most Americans. The anniversary of events celebrated by Ralph Waldo Emerson’s 1837 “Concord Hymn” passed largely unnoted and unnoticed, “the shot heard ‘round the world” turning into a quiet squib barely detected, save perhaps for the towns in Massachusetts where the events occurred.

The nation’s impending semiquincentennial — a fancy term for our 250th birthday, which we will celebrate next July — provides an excellent time for Americans to rediscover our nation’s history. In an ideal scenario, the more our fellow citizens recognize the sacrifices that our forebearers made to establish, as Lincoln noted, “a new nation, conceived in liberty and dedicated to the proposition that all men are created equal,” the more we might cherish, value, and nurture those freedoms today.
