In July Congress adopted the Olive Branch Petition, a final attempt to achieve an understanding with the Crown. The petition appealed directly to King George III to cease hostilities and restore harmony. But, unwilling to challenge the supremacy of Parliament, he refused to acknowledge the plea and proclaimed the Colonies to be in a state of rebellion.

During the winter of 1775–76, as the war intensified, all chance for accommodation vanished. Congress, for the first time representing all Thirteen Colonies because Georgia had sent Delegates in the fall, disclaimed allegiance to Parliament, created a navy, and appointed a committee of foreign affairs. Nevertheless the patriots, despite their mounting influence in the provincial assemblies, felt they needed more public support and hesitated to urge a final break with the Crown.

The turning point came in January 1776 with publication in Philadelphia of the pamphlet Common Sense, authored anonymously by the recent English immigrant Thomas Paine. Attacking the “myth” of an evil Parliament and a benevolent King, he denounced George III for creating the Colonies’ miseries, condemned the British constitution as well as monarchy in general, and exhorted his fellow Americans to declare independence immediately. The pamphlet, widely reprinted, was purchased by many thousands of people and read by thousands more. It created a furor. From Georgia to New Hampshire, independence became the major topic of discussion and debate. The Revolutionaries won thousands of converts.

In May Congress took a bold step toward political freedom by authorizing the Colonies to form permanent governments. Those that had not done so began to oust Crown officials and draft constitutions. Independence, though not yet officially declared, was for all practical purposes a reality.

The official movement for independence took root in the provincial assemblies. The North Carolina assembly in April 1776 instructed its congressional Delegates to vote for the issue should it be proposed. The next month, on May 4, Rhode Island announced its independence publicly—the first colony to do so. But it was Virginia that prodded Congress to action. On May 15 a Williamsburg convention declared Virginia independent and authorized its delegation at Philadelphia to propose a similar course for the Colonies. On June 7 the delegation’s leader, Richard Henry Lee, introduced the following resolution:

That these United Colonies are, and of right ought to be, free and independent States, that they are absolved from all allegiance to the British Crown, and that all political connection between them and the State of Great Britain is, and ought to be, totally dissolved.

The resolution also incorporated proposals to form foreign alliances; and to devise a plan for confederation, which would be submitted to the Colonies for their approval.

Despite the enthusiastic response of many Delegates, some of them, though they foresaw the inevitability of independence, objected to the timing. They believed the decision should reflect the desires of the people as expressed through the provincial assemblies and pointed out that the Middle Colonies, not yet ripe for freedom, needed more time for deliberation. On June 10 the moderates obtained a postponement of consideration of the Lee resolution until July 1.

On June 11 the Revolutionaries, undaunted by the delay and convinced of their ultimate victory, persuaded Congress to appoint a committee to draft a declaration of independence. Three of its five members, John Adams, Benjamin Franklin, and Thomas Jefferson, were Revolutionaries. Roger Sherman disliked extremism but had recently backed the independence movement. The most unlikely member, Robert R. Livingston, had stood in the front ranks of opposition to Lee’s resolution. Possibly he was appointed to exert a moderating effect on its supporters or, conversely, in the hope that his membership would help swing over the conservative New York delegation.
