The 1776 Declaration of Independence explained rights and the legitimacy of government while listing accusations against the British king, providing a political justification for colonial independence. Its language of equality stood in tension with realities such as slavery. Later social movements and interpretations continued to expand the text's meaning.
Background
Believe me, dear Sir: there is not in the British empire a man who more cordially loves a union with Great Britain than I do. But, by the God that made me, I will cease to exist before I yield to a connection on such terms as the British Parliament propose; and in this, I think I speak the sentiments of America.
By the time the Declaration of Independence was adopted in July 1776, the Thirteen Colonies and Kingdom of Great Britain had been at war for over a year. Relations had been deteriorating between the colonies and the mother country since 1763. In 1767, Parliament enacted a series of measures designed to increase revenue from the colonies, including the Stamp Act of 1765 and the Townshend Acts, which it believed were a legitimate means of having the colonies pay their fair share of the costs of remaining a part of the British Empire.
Lee Resolution
On the same day that Congress passed Adams' preamble, the Virginia Convention set the stage for a formal Congressional declaration of independence. On May 15, the Convention instructed Virginia's congressional delegation "to propose to that respectable body to declare the United Colonies free and independent States, absolved from all allegiance to, or dependence upon, the Crown or Parliament of Great Britain". In accordance with those instructions, Richard Henry Lee of Virginia presented a three-part resolution to Congress on June 7. The motion was seconded by John Adams, calling on Congress to declare independence, form foreign alliances, and prepare a plan of colonial confederation.
The part of the resolution relating to declaring independence read: "Resolved, 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."
Draft and adoption
Political maneuvering was setting the stage for an official declaration of independence even while a document was being written to explain the decision. On June 11, 1776, Congress appointed the Committee of Five to draft a declaration, including John Adams of Massachusetts, Benjamin Franklin of Pennsylvania, Thomas Jefferson of Virginia, Robert R. Livingston of New York, and Roger Sherman of Connecticut.
The committee took no minutes, so there is some uncertainty about how the drafting process proceeded; contradictory accounts were written many years later by Jefferson and Adams, too many years to be regarded as entirely reliable, although their accounts are frequently cited. What is certain is that the committee discussed the general outline which the document should follow and decided that Jefferson would write the first draft. The committee in general, and Jefferson in particular, thought that Adams should write the document, but Adams persuaded them to choose Jefferson and promised to consult with him personally.
Jefferson largely wrote the Declaration of Independence in isolation between June 11, 1776, and June 28, 1776, from the second floor of a three-story home he was renting at 700 Market Street in Philadelphia, now called the Declaration House and within walking distance of Independence Hall. Considering Congress's busy schedule, Jefferson probably had limited time for writing over these 17 days, and he likely wrote his first draft quickly.
Examination of the text of the early Declaration drafts reflects the influence that John Locke, the Enlightenment philosopher, and Thomas Paine, author of Common Sense, had on Jefferson. He then consulted the other members of the Committee of Five who offered minor changes, and then produced another copy incorporating these alterations. The committee presented this copy to the Congress on June 28, 1776. The title of the document was "A Declaration by the Representatives of the United States of America, in General Congress assembled."
