Independence, Declaration of, in U.S. history, document that was approved by the Continental Congress on July 4, 1776, and that announced the separation of 13 North American British colonies from Great Britain. It explained why the Congress on July 2 "unanimously" by the votes of 12 colonies (with New York abstaining) had resolved that "these United Colonies are, and of right ought to be Free and Independent States." Accordingly, the day on which final separation was officially voted was July 2, although the 4th, the day on which the Declaration of Independence was adopted, has always been celebrated in the United States as the great national holiday--the Fourth of July, or Independence Day.

On April 19, 1775, when armed conflict began between Britain and the 13 colonies (the nucleus of the future United States), the Americans claimed that they sought only their rights within the British Empire. At that time few of the colonists consciously desired to separate from Britain. As the War of Independence proceeded during 1775-76 and Britain undertook to assert its sovereignty by means of large armed forces, making only a gesture toward conciliation, the majority of Americans increasingly came to believe that they must secure their rights outside the empire. The losses and restrictions that came from the war greatly widened the breach between the colonies and the mother country; moreover, it was necessary to assert independence in order to secure as much French aid as possible.

On April 12, 1776, the revolutionary convention of North Carolina specifically authorized its delegates in Congress to vote for independence; and on May 15 the Virginia convention instructed its deputies to offer the motion that was finally adopted on July 2. The motion was brought forward in the Congress by Richard Henry Lee on June 7. By that time the Congress had already taken long steps toward severing ties with Britain. It had denied Parliamentary sovereignty over the colonies as early as Dec. 6, 1775, and it had declared on May 10, 1776, that the authority of the king ought to be "totally suppressed," advising all the several colonies to establish governments of their own choice.

The passage of Lee's resolution was delayed for several reasons. Some of the delegates had not yet received authorization to vote for separation; a few were opposed to taking the final step; and several men, among them John Dickinson, believed that the formation of a central government, together with attempts to secure foreign aid, should precede it. However, a committee consisting of Thomas Jefferson, John Adams, Benjamin Franklin, Roger Sherman, and Robert R. Livingston was promptly chosen on June 11 to prepare a statement justifying the decision to assert independence, should it be taken. The document was prepared, and on July 1 nine delegations voted for separation, despite warm opposition on the part of Dickinson. On the following day, with the New York delegation abstaining only because it lacked permission to act, the Lee resolution was adopted. (The convention of New York gave its consent on July 9, and the New York delegates voted affirmatively on July 15.) On July 19 the Congress ordered the document to be engrossed as "The Unanimous Declaration of the Thirteen United States of America." It was accordingly put on parchment, probably by Timothy Matlack of Philadelphia. Members of the Congress present on August 2 affixed their signatures to this parchment copy on that day, and others later. The last signer was Thomas McKean of Delaware, whose name was not placed on the document before 1777.

The Declaration of Independence was written largely by Jefferson, who had displayed talent as a political philosopher and polemicist in his A Summary View of the Rights of British America, published in 1774. At the request of his fellow committee members he wrote the first draft. The members of the committee made a number of merely verbal changes, and they also expanded somewhat the list of charges against the king. The Congress made more substantial changes, deleting a condemnation of the British people, a reference to "Scotch & foreign mercenaries" (there were Scots in the Congress), and a denunciation of the African slave trade (this being offensive to some Southern and New England delegates).

It can be said, as John Adams did, that the declaration contained nothing really novel in its political philosophy, which was derived from John Locke, Algernon Sidney, and other English theorists. It may also be asserted that the argument offered was not without flaws in history and logic. Substantially abandoning contention on the basis of the rights of Englishmen, the declaration put forth the more fundamental doctrines of natural rights and of government under social contract. Claiming that Parliament never truly possessed sovereignty over the colonies and that the crown of right exercised it only under contract, the declaration contended that George III, with the support of a "pretended" legislature, had persistently violated the agreement between himself as governor and the Americans as the governed. A long list of accusations was offered toward proving this contention. The right and duty of revolution were then invoked. (see also human rights)

Few will now claim that government arose among men as Locke and Jefferson said it did, and the social-contract theory has lost vogue among political scientists. It is likewise true, from a British viewpoint, that Parliament and crown could not be separated and that the history of the colonies after 1607 was not entirely consistent with the assertion that Parliament had never as of right possessed sovereignty over them. Furthermore, the specific charges brought against the king were partisan and not uniformly defensible, and the general accusation that he intended to establish an "absolute Despotism" is hardly warranted. It should be added that several of the heaviest specific complaints condemned actions of the British government taken after the beginning of hostilities.

The defects in the Declaration of Independence are not sufficient to force the conclusion that the document is unsound. On the contrary, it was in essence morally just and politically valid. If the right of revolution cannot be established on historical grounds, it nevertheless rests solidly upon ethical ones. The right of the colonists to government ultimately of their own choice is valid. Some of the phrases of the declaration have steadily exerted profound influence in the United States, especially the proclamation that, "We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness." Although the meanings of these phrases, together with conclusions drawn from them, have been endlessly debated, the declaration has served to justify the extension of American political and social democracy.

The Declaration of Independence has also been a source of inspiration outside the United States. It encouraged Antonio de Nariño and Francisco de Miranda to strive toward overthrowing the Spanish empire in South America, and it was quoted with enthusiasm by the Marquis de Mirabeau during the French Revolution. It remains a great historical landmark in that it contained the first formal assertion by a whole people of their right to a government of their own choice. What Locke had contended for as an individual, the Americans proclaimed as a body politic; moreover, they made good the argument by force of arms.

Since 1952 the original parchment document of the Declaration of Independence has resided in the National Archives exhibition hall in Washington, D.C.

이 문서를 통해 최초로 국민의 정부 선택권이 조직체를 통해 공표되었다. 1776년 7월 2일 필라델피아에서 열린 제2차 대륙회의는 리처드 헨리 리가 요구한 독립 제안을 받아들이고(뉴욕 기권), 이후 독립기념일이 된 7월 4일에 독립선언서를 승인했다. 서명은 8월 2일부터 시작해 여러 달이 걸렸으며 마침내 56명이 서명했다.

독립선언서는 주로 존 로크의 이론에 바탕을 두고 토머스 제퍼슨이 초안을 잡았으며 영국 국왕 조지 3세에 의해 침해당했다고 대륙회의가 주장해온 인간의 자연권과 계약에 의한 통치 원칙을 천명했다. 또한 식민지에게는 영국에 반기를 들 권리와 의무가 있다는 주장을 뒷받침하는 뜻에서 불만 요인들을 구체적으로 열거했다. 발표될 당시에는 별 관심을 끌지 못했지만 19세기에 영향력이 늘어났으며 미국에서는 연방 헌법 다음으로 존중받고 있다. 워싱턴 D. C.의 국립문서국에 원본이 전시되어 있다.
