The Second Continental Congress was a convention of delegates from the Thirteen British Colonies in North America that met from 10 May 1775 to 1 March 1781, when it was superseded by the Congress of the Confederation under the newly ratified Articles of Confederation. Convened in Philadelphia, Pennsylvania, initially at Carpenters' Hall and later at the Pennsylvania State House (now Independence Hall), it served as the de facto national government of the united colonies - and after 4 July 1776, of the United States of America - through the entirety of the Revolutionary War. The Congress operated without a formal constitutional charter for most of its existence, exercising powers by necessity rather than by explicit delegation from the colonies or states it represented.

The Congress emerged directly from the First Continental Congress (1774) and was called into session weeks after the opening engagements of the Revolutionary War at Lexington and Concord (19 April 1775). Its membership overlapped significantly with that of its predecessor but included notable additions, among them Benjamin Franklin, Thomas Jefferson, and John Hancock, who served as its president from 24 May 1775 to 29 October 1777. The body's early deliberations balanced two positions that coexisted uneasily: continued attempts at reconciliation with the British Crown - most notably through the Olive Branch Petition of 8 July 1775 - and the practical organization of armed resistance through the creation of the Continental Army and the appointment of George Washington as its commander-in-chief on 15 June 1775. The failure of reconciliation efforts, combined with King George III's proclamation of rebellion (23 August 1775) and the publication of Thomas Paine's Common Sense (10 January 1776), shifted the balance toward independence. On 2 July 1776 the Congress voted to declare independence from Great Britain; on 4 July 1776 it formally adopted the Declaration of Independence, drafted primarily by Jefferson with revisions by Franklin, John Adams, and the Congress as a whole.

Beyond independence, the Congress's major acts included the adoption and transmission to the states of the Articles of Confederation (drafted 1776-1777, submitted 15 November 1777, ratified 1 March 1781); the management of foreign diplomacy, including the negotiation of the Franco-American Alliance (6 February 1778); the issuance of Continental Currency and war financing; and the general direction of the war effort, though its lack of taxing authority and dependence on state cooperation produced chronic difficulties in both areas. The structural tensions between the Congress's broad assumed powers and its weak formal authority are discussed on the History page.

The historical and constitutional significance of the Second Continental Congress remains a subject of scholarly discussion. Questions about the legal basis of its authority, the extent to which it represented a proto-national government versus a league of sovereign states, and the relationship between its actions and later constitutional theory bear on long-running debates about American federalism and the founding period.

There is broad historical consensus on the basic chronology, membership, and documentary record of the Second Continental Congress. Interpretive questions - including the extent of colonial unity, the motivations of delegates, the role of economic versus ideological factors in driving independence, and the Congress's implications for later constitutional development - remain subjects of active scholarly debate. See the historical consensus page for an overview of areas of agreement.

• Constitutional legitimacy - Whether the Congress possessed genuine legal authority, and from what source that authority derived, is disputed. Some scholars ground its legitimacy in popular delegation from the colonial assemblies; others argue it was a revolutionary body whose authority rested on consent and success rather than legal form. See Constitutional Legitimacy Viewpoint.

• Representativeness - The degree to which Congress delegates represented the broader colonial population - including backcountry settlers, the laboring poor, loyalists, enslaved people, and women - is contested. Some historians emphasize the Congress as an expression of broad revolutionary sentiment; others characterize it as an assembly dominated by merchant, planter, and professional elites whose interests shaped its decisions. See Representativeness Viewpoint.

• Independence as outcome vs. objective - Historians differ on whether independence was the deliberate goal of congressional leadership from an early stage or an outcome reached reluctantly and incrementally under the pressure of events. See Independence as Intent Viewpoint.

• Slavery and the founding compromise - The Congress's handling of slavery - including the deletion of Jefferson's anti-slavery passage from the Declaration and the accommodation of slaveholding interests throughout - is interpreted variously as a pragmatic necessity for colonial unity, what some historians characterize as a founding moral failure, or evidence of the ideological limits of revolutionary liberalism. See Slavery and the Founding Viewpoint.
