How a Secretive Assembly of Delegates Transformed Thirteen Colonies Into a New Nation

In short: The Continental Congress began as a desperate attempt to repair a fraying relationship with the British Crown. Within two years, this provisional body evolved from a cautious group of petitioners into the architects of a revolution, ultimately severing all ties to England and forging a new, independent sovereign nation.

The Continental Congress refers to the legislative bodies that convened in Philadelphia between 1774 and 1781. The First Continental Congress met in September 1774, prompted by the British Parliament’s passage of the Intolerable Acts. Fifty-six deputies from twelve colonies gathered to address grievances, asserting rights such as trial by jury and property ownership. Rather than seeking immediate independence, they petitioned the King for redress and organized a trade boycott against British goods, hoping to force a policy shift.

By the time the Second Continental Congress assembled in May 1775, armed conflict had already erupted at Lexington, Concord, and Bunker Hill. The delegates took on the responsibilities of a provisional government, establishing a postal service, creating a navy, and appointing George Washington as commander in chief. Despite these actions, many members still sought reconciliation. They sent the Olive Branch Petition to King George III in July 1775, but the King refused to engage, instead declaring the colonists to be in open rebellion.

This rejection proved a turning point, pushing the Congress toward total separation. On July 2, 1776, the body resolved that the colonies were free and independent states, formally approving the Declaration of Independence two days later. The Congress continued to manage the Revolutionary War until the Articles of Confederation came into force in March 1781, legalizing the powers the body had exercised since 1775. This transition marked the birth of the Confederation Congress, which served as the first federal government until the U.S. Constitution took effect in 1789.
