The United States Declaration of Independence (formally The unanimous Declaration of the thirteen united States of America) is the pronouncement adopted by the Second Continental Congress meeting in Philadelphia, Pennsylvania, on July 4, 1776. The Declaration explained why the Thirteen Colonies at war with the Kingdom of Great Britain regarded themselves as thirteen independent sovereign states, no longer under British rule. With the Declaration, these new states took a collective first step toward forming the United States of America. The declaration was signed by representatives from New Hampshire, Massachusetts Bay, Rhode Island, Connecticut, New York, New Jersey, Pennsylvania, Maryland, Delaware, Virginia, North Carolina, South Carolina, and Georgia.

The Lee Resolution for independence was passed by the Second Continental Congress on July 2 with no opposing votes. The Committee of Five had drafted the Declaration to be ready when Congress voted on independence. John Adams, a leader in pushing for independence, had persuaded the committee to select Thomas Jefferson to compose the original draft of the document, which Congress edited to produce the final version. The Declaration was a formal explanation of why Congress had voted to declare independence from Great Britain, more than a year after the outbreak of the American Revolutionary War. Adams wrote to his wife Abigail, "The Second Day of July 1776, will be the most memorable Epocha, in the History of America" – although Independence Day is actually celebrated on July 4, the date that the wording of the Declaration of Independence was approved.

After ratifying the text on July 4, Congress issued the Declaration of Independence in several forms. It was initially published as the printed Dunlap broadside that was widely distributed and read to the public. The source copy used for this printing has been lost and may have been a copy in Thomas Jefferson's hand. Jefferson's original draft is preserved at the Library of Congress, complete with changes made by John Adams and Benjamin Franklin, as well as Jefferson's notes of changes made by Congress. The best-known version of the Declaration is a signed copy that is displayed at the National Archives in Washington, D.C., and which is popularly regarded as the official document. This engrossed copy (finalized, calligraphic copy) was ordered by Congress on July 19 and signed primarily on August 2.

The sources and interpretation of the Declaration have been the subject of much scholarly inquiry. The Declaration justified the independence of the United States by listing 27 colonial grievances against King George III and by asserting certain natural and legal rights, including a right of revolution. Its original purpose was to announce independence, and references to the text of the Declaration were few in the following years. Abraham Lincoln made it the centerpiece of his policies and his rhetoric, as in the Gettysburg Address of 1863. Since then, it has become a well-known statement on human rights, particularly its second sentence:

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.

This has been called "one of the best-known sentences in the English language", containing "the most potent and consequential words in American history". The passage came to represent a moral standard to which the United States should strive. This view was notably promoted by Lincoln, who considered the Declaration to be the foundation of his political philosophy and argued that it is a statement of principles through which the United States Constitution should be interpreted.

The Declaration of Independence inspired many similar documents in other countries, the first being the 1789 Declaration of United Belgian States issued during the Brabant Revolution in the Austrian Netherlands. It also served as the primary model for numerous declarations of independence in Europe and Latin America, as well as Africa (Liberia) and Oceania (New Zealand) during the first half of the 19th century.

Publication and reaction

After Congress approved the final wording of the Declaration on July 4, a handwritten copy was sent a few blocks away to the printing shop of John Dunlap. Through the night, Dunlap printed about 200 broadsides for distribution. Soon, it was being read to audiences and reprinted in newspapers throughout the 13 states. The first formal public readings of the document took place on July 8, in Philadelphia (by John Nixon in the yard of Independence Hall), Trenton, New Jersey, and Easton, Pennsylvania; the first newspaper to publish it was the Pennsylvania Evening Post on July 6. A German translation of the Declaration was published in Philadelphia by July 9.

President of Congress John Hancock sent a broadside to General George Washington, instructing him to have it proclaimed "at the Head of the Army in the way you shall think it most proper". Washington had the Declaration read to his troops in New York City on July 9, with thousands of British troops on ships in the harbor. Washington and Congress hoped that the Declaration would inspire the soldiers, and encourage others to join the army. After hearing the Declaration, crowds in many cities tore down and destroyed signs or statues representing royal authority. An equestrian statue of King George in New York City was pulled down and the lead used to make musket balls.

British officials in North America sent copies of the Declaration to Great Britain. It was published in British newspapers beginning in mid-August, it had reached Florence and Warsaw by mid-September, and a German translation appeared in Switzerland by October. The first copy of the Declaration sent to France got lost, and the second copy arrived only in November 1776. It reached Portuguese America by Brazilian medical student "Vendek" José Joaquim Maia e Barbalho, who had met with Thomas Jefferson in Nîmes.

The Spanish-American authorities banned the circulation of the Declaration, but it was widely transmitted and translated: by Venezuelan Manuel García de Sena, by Colombian Miguel de Pombo, by Ecuadorian Vicente Rocafuerte, and by New Englanders Richard Cleveland and William Shaler, who distributed the Declaration and the United States Constitution among Creoles in Chile and Indians in Mexico in 1821. The North Ministry did not give an official answer to the Declaration, but instead secretly commissioned pamphleteer John Lind to publish a response entitled Answer to the Declaration of the American Congress. British Tories denounced the signers of the Declaration for not applying the same principles of "life, liberty, and the pursuit of happiness" to African Americans. Thomas Hutchinson, the former royal governor of Massachusetts, also published a rebuttal. These pamphlets challenged various aspects of the Declaration. Hutchinson argued that the American Revolution was the work of a few conspirators who wanted independence from the outset, and who had finally achieved it by inducing otherwise loyal colonists to rebel. Lind's pamphlet had an anonymous attack on the concept of natural rights written by Jeremy Bentham, an argument that he repeated during the French Revolution. Both pamphlets asked how the American slaveholders in Congress could proclaim that "all men are created equal" without freeing their own slaves.

William Whipple, a signer of the Declaration of Independence who had fought in the war, freed his slave Prince Whipple because of revolutionary ideals. In the postwar decades, other slaveholders also freed their slaves; from 1790 to 1810, the percentage of free blacks in the Upper South increased to 8.3 percent from less than one percent of the black population. All Northern states abolished slavery by 1804.

History of the documents

The official copy of the Declaration of Independence was the one printed on July 4, 1776, under Jefferson's supervision. It was sent to the states and to the Army and was widely reprinted in newspapers. The slightly different "engrossed copy" (shown at the top of this article) was made later for members to sign. The engrossed version is the one widely distributed in the 21st century. Note that the opening lines differ between the two versions.

The copy of the Declaration that was signed by Congress is known as the engrossed or parchment copy. It was probably engrossed (that is, carefully handwritten) by clerk Timothy Matlack. A facsimile made in 1823 has become the basis of most modern reproductions rather than the original because of poor conservation of the engrossed copy through the 19th century. In 1921, custody of the engrossed copy of the Declaration was transferred from the State Department to the Library of Congress, along with the United States Constitution. After the Japanese attack on Pearl Harbor in 1941, the documents were moved for safekeeping to the United States Bullion Depository at Fort Knox in Kentucky, where they were kept until 1944. In 1952, the engrossed Declaration was transferred to the National Archives and is now on permanent display at the National Archives in the "Rotunda for the Charters of Freedom".

The document signed by Congress and enshrined in the National Archives is usually regarded as the Declaration of Independence, but historian Julian P. Boyd argued that the Declaration, like Magna Carta, is not a single document. Boyd considered the printed broadsides ordered by Congress to be official texts, as well. The Declaration was first published as a broadside that was printed the night of July 4 by John Dunlap of Philadelphia. Dunlap printed about 200 broadsides, of which 26 are known to survive. The 26th copy was discovered in The National Archives in England in 2009.

In 1777, Congress commissioned Mary Katherine Goddard to print a new broadside that listed the signers of the Declaration, unlike the Dunlap broadside. Nine copies of the Goddard broadside are known to still exist. A variety of broadsides printed by the states are also extant, including seven copies of the Solomon Southwick broadside, one of which was acquired by Washington University in St. Louis in 2015.

Several early handwritten copies and drafts of the Declaration have also been preserved. Jefferson kept a four-page draft that late in life he called the "original Rough draught". It is not known how many drafts Jefferson wrote prior to this one, and how much of the text was contributed by other committee members. In 1947, Boyd discovered a fragment of an earlier draft in Jefferson's handwriting. Jefferson and Adams sent copies of the rough draft to friends, with slight variations.

During the writing process, Jefferson showed the rough draft to Adams and Franklin, and perhaps to other members of the drafting committee, who made a few more changes. Franklin, for example, may have been responsible for changing Jefferson's original phrase "We hold these truths to be sacred and undeniable" to "We hold these truths to be self-evident". Jefferson incorporated these changes into a copy that was submitted to Congress in the name of the committee. The copy that was submitted to Congress on June 28 has been lost and was perhaps destroyed in the printing process, or destroyed during the debates in accordance with Congress's secrecy rule.

On April 21, 2017, it was announced that a second engrossed copy had been discovered in the archives at West Sussex County Council in Chichester, England. Named by its finders the "Sussex Declaration", it differs from the National Archives copy (which the finders refer to as the "Matlack Declaration") in that the signatures on it are not grouped by States. How it came to be in England is not yet known, but the finders believe that the randomness of the signatures points to an origin with signatory James Wilson, who had argued strongly that the Declaration was made not by the States but by the whole people.
