The Second Continental Congress was a meeting of delegates from the Thirteen Colonies in America that united in the American Revolutionary War.

It convened on May 10, 1775, with representatives from 12 of the colonies in Philadelphia, Pennsylvania shortly after the Battles of Lexington and Concord, succeeding the First Continental Congress which met in Philadelphia from September 5 to October 26, 1774.

The Second Congress functioned as a de facto national government at the outset of the Revolutionary War by raising armies, directing strategy, appointing diplomats, and writing petitions such as the Declaration of the Causes and Necessity of Taking Up Arms and the Olive Branch Petition

All thirteen colonies were represented by the time the Congress adopted the Lee Resolution which declared independence from Britain on July 2, 1776, and the congress agreed to the Declaration of Independence two days later.
