September 9
Continental Congress Names Nation United States
The Second Continental Congress in Philadelphia resolved to replace references to the 'United Colonies' with 'United States of America' in official documents, formalizing a national identity during the Revolutionary War.
Summary
By mid-1776, the American colonies had declared independence from Britain on July 4, yet still referred to themselves collectively as the United Colonies in official documents. The Second Continental Congress, meeting in Philadelphia, sought a formal national identity as war with Britain intensified and foreign alliances became essential. On September 9, delegates resolved that the new nation would henceforth be called the United States of America, replacing earlier terminology. This change appeared in subsequent resolutions and correspondence. The decision reflected growing unity among the thirteen colonies and clarified their status as a sovereign entity to European powers.
Context
By the summer of 1776, the thirteen colonies had broken politically with Britain through the Declaration of Independence, yet many official papers and commissions still employed the older designation 'United Colonies,' which implied a subordinate status under British authority. The Second Continental Congress, convened in Philadelphia since 1775 to coordinate the colonial response to British policies, continued to direct military operations and seek foreign assistance as fighting intensified across the northern colonies.
European recognition and alliances required the emerging polity to present itself as a coherent sovereign power rather than a temporary league of rebellious provinces. Delegates therefore addressed inconsistencies in terminology that could undermine diplomatic credibility at a moment when British forces were advancing and supplies from abroad remained critical.
What Happened
On September 9, 1776, while meeting at the Pennsylvania State House, the Second Continental Congress took up routine resolutions concerning army payments and administrative matters. One measure directed that the phrase 'United Colonies' be supplanted by 'United States' in all future continental commissions and instruments where the older wording had appeared.
The resolution passed without recorded opposition. It built upon the phrasing already present in the title of the July Declaration of Independence, which had referred to the 'thirteen united States of America,' but now extended the new style uniformly across congressional business.
Philadelphia served as the setting for this procedural yet symbolically significant action, undertaken by delegates representing each of the thirteen colonies under the presidency of John Hancock.
Aftermath
The updated terminology quickly entered congressional correspondence, military appointments, and early diplomatic notes sent abroad. It helped European observers, particularly in France and the Netherlands, view the conflict as one between established powers rather than an internal British dispute.
Within weeks the new name appeared in resolutions and letters emanating from Philadelphia, reinforcing the sense of a single national entity managing the war effort.
Legacy
The designation 'United States of America' became the enduring official title of the country and shaped its constitutional language, appearing in the Articles of Confederation and the preamble to the 1787 Constitution. It embedded the principle of a voluntary union of states into the nation's self-conception.
Scholars regard the September 9 resolution as an early milestone in the deliberate construction of American nationhood, illustrating how revolutionary leaders used precise language to assert sovereignty and continuity amid armed struggle.
Why It Matters
The naming formalized the break from colonial status and provided a enduring national title that shaped American identity and diplomacy. It preceded the Articles of Confederation and influenced later constitutional language. The resolution marked a key step in the transition from revolutionary alliance to independent republic during the founding era.
