From Wilson to Kennedy: The Declaration's American Legacy in the 20th Century

Throughout the 20th century, the ideals and principles enshrined in the Declaration of Independence evolved into a key component of American presidents' rhetoric, serving to justify the nation's expanding global presence.

On January 20, 1961, John F. Kennedy, upon taking the presidential oath amidst a world defined by the Cold War, nuclear threats, and the Cuban Revolution, referenced this historical lineage. In his inaugural address, Kennedy described Americans as "heirs of the first revolution." He underscored that the foundational beliefs fought for by the nation's founders "are still the subject of debate around the world." Kennedy pledged that the United States would "bear any burden" and "meet any hardship" to ensure "the survival and the success of freedom."

This framing, rooted in the Declaration of Independence, provided a consistent ideological basis for American foreign policy across different administrations. Presidents utilized these core tenets to articulate the nation's role and responsibilities on the international stage, linking American actions to the universal pursuit of liberty and self-determination. The article explores how this historical and philosophical inheritance shaped America's engagement with the world during a tumultuous century.
