Dickinson was one of the delegates from Pennsylvania to the First Continental Congress in 1774 and the Second Continental Congress in 1775 and 1776. In support of the cause, he continued to contribute declarations in the name of the Congress. Dickinson wrote the Olive Branch Petition as the Second Continental Congress' last attempt for peace with Britain (King George III did not even read the petition). But through it all, agreeing with New Castle County's George Read and many others in Philadelphia and the Lower Counties, Dickinson's object was reconciliation, not independence and revolution.
