The Congress balanced the interests of the different colonies and also established itself as the official colonial liaison to Great Britain. As the war progressed, the Congress became the effective national government of the country, and, as such, conducted diplomacy on behalf of the new United States.
In 1774, the British Parliament passed a series of laws collectively known as the Intolerable Acts, with the intent to suppress unrest in colonial Boston by closing the port and placing it under martial law. In response, colonial protestors led by a group called the Sons of Liberty issued a call for a boycott. Merchant communities were reluctant to participate in such a boycott unless there were mutually agreed upon terms and a means to enforce the boycott’s provisions. Spurred by local pressure groups, colonial legislatures empowered delegates to attend a Continental Congress which would set terms for a boycott. The colony of Connecticut was the first to respond.
In session from July 30 to August 4, 1619, the General Assembly was the first representative governing body to meet in North America, or anywhere in the Americas, and has continued to meet to the present day.
The Congress first met in Philadelphia on September 5, 1774, with delegates from each of the 13 colonies except Georgia. On October 20, the Congress adopted the Articles of Association, which stated that if the Intolerable Acts were not repealed by December 1, 1774, a boycott of British goods would begin in the colonies. The Articles also outlined plans for an embargo on exports if the Intolerable Acts were not repealed before September 10, 1775.
On October 21, the delegates approved separate statements for the people of Great Britain and the North American colonies, explaining the colonial position, and on October 26 a similar address was approved for the people of Quebec.
Furthermore, on October 26, the delegates drafted a formal petition outlining the colonists' grievances for British King George III. Many delegates were skeptical about changing the king’s attitude towards the colonies, but believed that every opportunity should be exhausted to de-escalate the conflict before taking more radical action. They did not draft such a letter to the British Parliament as the colonists viewed the Parliament as the aggressor behind the recent Intolerable Acts. Lastly, not fully expecting the standoff in Massachusetts to explode into full-scale war, the Congress agreed to reconvene in Philadelphia on May 10, 1775.
By the time Congress met again, war was already underway, and thus the delegates to the Second Continental Congress formed the Continental Army and dispatched George Washington to Massachusetts as its commander. Meanwhile, Congress drafted the Olive Branch Petition, which attempted to suggest means of resolving disputes between the colonies and Great Britain. Congress sent the petition to King George III on July 8, but he refused to receive it.
As British authority crumbled in the colonies, the Continental Congress effectively took over as the de facto national government, thereby exceeding the initial authority granted to it by the individual colonial governments. However, the local groups that had formed to enforce the colonial boycott continued to support the Congress. The Second Congress continued to meet until March 1, 1781, when the Articles of Confederation that established a new national government for the United States took effect.
As the de facto national government, the Continental Congress assumed the role of negotiating diplomatic agreements with foreign nations. The British Parliament banned trade with the colonies and authorized the seizure of colonial vessels on December 23. These actions served to further erode the positions of anti-independence moderates in Congress and bolster those of pro-independence leaders. On April 6, 1776, Congress responded to Parliament's actions by opening American ports to all foreign ships except British vessels. Reports from American agent Arthur Lee in London also served to support the revolutionary cause. Lee’s reports suggested that France was interested in assisting the colonies in their fight against Great Britain.
With a peaceful resolution increasingly unlikely in 1775, Congress began to explore other diplomatic channels and dispatched congressional delegate Silas Deane to France in April of 1776.
