As a result, in July, the Assembly sent a split delegation to the Continental Congress: Joseph Galloway, Charles Humphreys, and Samuel Rhoads were all moderates, while Biddle, Thomas Mifflin, John Morton, and George Ross were radicals.
That first Continental Congress produced a statement or Declaration of Rights, as well as a plan of union and pleas to King George to resolve the issues that separated the colonies from Great Britain.
They also produced a renewal of the Continental Association, the non-importation agreement adopted in the wake of the Stamp Act protests.
Biddle was a member of the committee that drafted the Declaration of Rights and later oversaw the printing of the resolutions the Congress had passed.
Early in 1775, Governor John Penn called the Assembly into session, intent on having Pennsylvania send its own declarations to the crown.
