Which body adopted the Declaration of Independence in 1776, the event honored by America250?

The Second Continental Congress adopted the Declaration of Independence in 1776, the event honored by America250.

The congress met in Philadelphia beginning in May 1775, after fighting had already begun between colonial forces and Great Britain. It acted as the de facto national government during the Revolutionary War, directing the war effort, appointing military leaders, seeking foreign support, and managing diplomatic affairs.

On July 2, 1776, the congress passed the Lee Resolution declaring the colonies independent. Two days later, it adopted the Declaration of Independence, which explained the decision and presented it to a wider audience. The First Continental Congress had met in 1774 and did not declare independence, making the two congresses an important distinction.
