For 250 years and counting, Americans have celebrated Independence Day on July 4 through fireworks, concerts, parades, barbecues, and more. By contrast, Constitution Day arrives soon after, on September 17, with far less fanfare. It is not a time to hear patriotic medleys on the radio, enjoy 20% off a new air-conditioner, watch a hot-dog-eating contest, or exchange cheerful greetings with neighbors. The observance marks the anniversary of the moment when 39 delegates signed our nation’s founding document at the Constitutional Convention in Philadelphia on September 17, 1787. Constitution Day came and went last month with little public awareness. But the observance should inspire all Americans to protect our cherished Constitution throughout the year.

Presidents of the United States recite an oath of office to “preserve, protect and defend the Constitution of the United States.” This oath, familiar to many Americans who watch Inauguration Day ceremonies, is mandated by the Constitution itself (Article II, Section 1, Clause 8). Public officials, judges, service members, and lawyers like me also swear oaths to support the Constitution as part of their public or professional roles.
