The Second Continental Congress was a convention of delegates from the Thirteen Colonies that started meeting in the spring of 1775 in Philadelphia , Pennsylvania . It succeeded the First Continental Congress , which met in Philadelphia between September 5, 1774 and October 26, 1774. The Second Congress managed the Colonial war effort and moved incrementally towards independence , adopting the United States Declaration of Independence on July 4, 1776. The Congress acted as the de facto national government of what became the United States by raising armies, directing strategy, appointing diplomats, and making formal treaties such as the Olive Branch Petition .
The Second Continental Congress came together on May 10, 1775, effectively reconvening the First Continental Congress. Many of the 56 delegates who attended the first meeting were in attendance at the second, and the delegates appointed the same president ( Peyton Randolph ) and secretary ( Charles Thomson ). Notable new arrivals included Benjamin Franklin of Pennsylvania and John Hancock of Massachusetts. Within two weeks, Randolph was summoned back to Virginia to preside over the House of Burgesses ; he was replaced in the Virginia delegation by Thomas Jefferson , who arrived several weeks later. Henry Middleton was elected as president to replace Randolph, but he declined. Hancock was elected president on May 24.
Delegates from twelve of the Thirteen Colonies were present when the Second Continental Congress convened. Georgia had not participated in the First Continental Congress and did not initially send delegates to the Second. On May 13, 1775, Lyman Hall was admitted as a delegate from the Parish of St. John's in the Colony of Georgia, not as a delegate from the colony itself.  On July 4, 1775, revolutionary Georgians held a Provincial Congress to decide how to respond to the American Revolution , and that congress decided on July 8 to send delegates to the Continental Congress. They arrived on July 20. 
The First Continental Congress had sent entreaties to King George III to stop the Coercive Acts ; they had also created the Continental Association to establish a coordinated protest of those acts, putting a boycott on British goods. The Second Continental Congress met on May 10, 1775 to plan further responses if the British government had not repealed or modified the acts; however, the American Revolutionary War had already started by that time with the Battles of Lexington and Concord , and the Congress was called upon to take charge of the war effort.
For the first few months of the war, the Patriots carried on their struggle in an ad-hoc and uncoordinated manner. They had seized arsenals, driven out royal officials, and besieged the British army in the city of Boston. On June 14, 1775, the Congress voted to create the Continental Army out of the militia units around Boston and appointed George Washington of Virginia as commanding general. On July 6, 1775 Congress approved a Declaration of Causes outlining the rationale and necessity for taking up arms in the Thirteen Colonies ."  On July 8, they extended the Olive Branch Petition to the British Crown as a final attempt at reconciliation; however, it was received too late to do any good. Silas Deane was sent to France as a minister (ambassador) of the Congress, and American ports were reopened in defiance of the British Navigation Acts .
The Continental Congress had no explicit legal authority to govern,  but it assumed all the functions of a national government, such as appointing ambassadors, signing treaties, raising armies, appointing generals, obtaining loans from Europe, issuing paper money (called " Continentals "), and disbursing funds. The Congress had no authority to levy taxes and was required to request money, supplies, and troops from the states to support the war effort. Individual states frequently ignored these requests.
Congress was moving towards declaring independence from the British Empire in 1776, but many delegates lacked the authority from their home governments to take such a drastic action. Advocates of independence moved to have reluctant colonial governments revise instructions to their delegations, or even replace those governments which would not authorize independence. On May 10, 1776, Congress passed a resolution recommending that any colony with a government that was not inclined toward independence should form one that was. On May 15, they adopted a more radical preamble to this resolution, drafted by John Adams , which advised throwing off oaths of allegiance and suppressing the authority of the Crown in any colonial government that still derived its authority from the Crown. That same day, the Virginia Convention instructed its delegation in Philadelphia to propose a resolution that called for a declaration of independence, the formation of foreign alliances, and a confederation of the states. The resolution of independence was delayed for several weeks, as advocates of independence consolidated support in their home governments.
On June 7, 1776, Richard Henry Lee offered a resolution before the Congress declaring the colonies independent. He also urged Congress to resolve "to take the most effectual measures for forming foreign Alliances" and to prepare a plan of confederation for the newly independent states.  Lee argued that independence was the only way to ensure a foreign alliance, since no European monarchs would deal with America if they remained Britain's colonies. American leaders had rejected the divine right of kings in the New World , but recognized the necessity of proving their credibility in the Old World .  Congress formally adopted the resolution of independence , but only after creating three overlapping committees to draft the Declaration, a Model Treaty , and the Articles of Confederation . The Declaration announced the states' entry into the international system; the model treaty was designed to establish amity and commerce with other states; and the Articles of Confederation established "a firm league" among the thirteen free and independent states. These three things together constituted an international agreement to set up central institutions for conducting vital domestic and foreign affairs. 
Congress finally approved the resolution of independence on July 2, 1776. They next turned their attention to a formal explanation of this decision, the United States Declaration of Independence which was approved on July 4 and published soon thereafter.
The Congress moved from Philadelphia to Baltimore in the winter of 1776 to avoid capture by British forces who were advancing on Philadelphia. Henry Fite's tavern was the largest building in Baltimore Town at the time and provided a comfortable location of sufficient size for Congress to meet. Its site at the western edge of town was beyond easy reach of the British Royal Navy 's ships should they try to sail up the harbor and the Patapsco River to shell the town. Congress was again forced to flee Philadelphia at the end of September 1777, as British troops occupied the city; they moved to York, Pennsylvania and continued their work.
Congress passed the Articles of Confederation on November 15, 1777, after more than a year of debate, and sent them to the states for ratification. Jefferson's proposal for a Senate to represent the states and a House to represent the people was rejected, but a similar proposal was adopted later in the United States Constitution . One issue of debate was large states wanting a larger say, nullified by small states who feared tyranny. The small states won and each state had one vote. Congress urged the individual states to pass the Articles as quickly as possible, but it took three and a half years for all the states to ratify them. The State Legislature of Virginia was the first of the Thirteen States to ratify the Articles on December 16, 1777, and the State Legislature of Maryland was the last on February 2, 1781.
