The preamble to the Declaration of Independence, drafted in 1776, includes this phrase: “We hold these truths to be self-evident, that all men are created equal.” For 250 years, these words have guided the country, shaped its democratic foundation, and helped define what it means to be American.

But, unlike other founding documents, the Declaration of Independence is not legally binding. Historian and political philosopher Danielle Allen, in considering the document, deemed it to be among “the most important memos ever written.”

Days after the United States celebrates its 250^th birthday, military historian Harry S. Laver discusses the nation’s formation through military rebellion, acts of heroism, and civil conflict. He also explores how the Declaration of Independence continues to inspire people around the world to fight for freedom and equality.

Laver, a professor in the college’s Department of Military History at the U.S. Army Command and General Staff College, has a doctorate in history from the University of Kentucky. He’s the author of several books, including the upcoming Grant and His Generals and The Leadership of Ulysses S. Grant: A General Who Will Fight.
