Answer:
Thomas Jefferson, age 33, arrived in Philadelphia on June 20, 1775, as a Virginia delegate to the Second Continental Congress. Fighting at Lexington, Concord, and Bunker Hill had already broken out between the colonists and British troops. Even so, most in Congress wanted to work out some mutual agreement with the mother country.
For more than a year, the Americans had sent petitions to England proclaiming their grievances against the British government. Colonists even appealed to the British people, pleading with them to elect different members of Parliament who would be more open to compromise. But the "British brethren" refused to do this.
Soon after Jefferson arrived in Philadelphia, Congress assigned him to draft a document explaining why the colonists had taken up arms against England. Even at this late date, the Congress still blamed only Parliament and the king's government ministers, not King George himself, for the growing conflict. Jefferson's Declaration of the Causes and Necessity for Taking Up Arms stopped short of declaring independence, but pointed out the folly of governing the American colonies from England.
