What purpose does the Declaration of Independence serve

Looking back on the Declaration of Independence almost 50 years later, Thomas Jefferson explained that the document’s purpose was never meant to be thoroughly original; its purpose wasn’t to articulate anything that hadn’t be said before, but to make the case for the American colonies in plain terms and persuade the world to see common sense. “It was intended to be an expression of the American mind,” Jefferson explains. He goes on to claim that “[the Declaration’s] authority rests then on the harmonizing sentiments of the day.” (Jefferson to Henry Lee, May 8, 1825) Jefferson finished his timeless defense of “life, liberty and the pursuit of happiness” in little more than two weeks, and like most writers, he was no stranger to the revision process. Between the Committee of Five and the Second Continental Congress, there were 86 edits to the document. The Second Continental Congress removed whole sections. Jefferson was most angered by the removal of one particular clause, a clause blaming the King for forcing the slave trade upon the American colonies. The final draft of the Declaration of Independence contains a preamble, a list of grievances, a formal declaration of independence, and signatures. This first part of the Declaration contains an assertion of individual rights. Perhaps the most famous line states, “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 part goes on to say that if the government tries to take these rights away, the people have the right to form a new government. Jefferson also addresses a counterclaim in this section, acknowledging that “Prudence, indeed, will dictate that Governments long established should not be changed for light and transient causes…” He counters by reminding his audience of the “long train of abuses and usurpations” that makes it “…their right, it is their duty, to throw off such Government, and to provide new Guards for their future security.”
The longest part of the Declaration begins with "He has refused his Assent to Laws" and goes on to list the unfair actions of the British king and Parliament. In their complaints, the colonists make it clear that they are angry with the British king and government for taking away their rights as English citizens. They point out that the king has ignored or changed their colonial governments, as well as their rights to a trial by jury. The colonists accuse the king of sending a hired army to force them to obey unjust laws. They say the king is “unfit to be the ruler of a free people.”

Note: The norms and structure of argumentative writing in the 18th century were different than they are in the 21st century. The list of grievances that serves as the Declaration’s evidence seems largely anecdotal by today’s standards. However, the Declaration’s claim and underlying assumption (big idea) are especially applicable to the writing standards of 21st-century classrooms.


The final paragraph, beginning with "We, therefore, the Representatives of the united States of America," affirms that the 13 colonies are free and independent states. It breaks all ties with the British government and people. As independent states, they can make trade agreements and treaties, wage war, and do whatever is necessary to govern themselves. This formal declaration of independence ends with important words. The words tell us what the signers of the Declaration of Independence were willing to give up for freedom: “…we mutually pledge to each other our Lives, our Fortunes and our sacred Honor.”
There are 56 signatures on the Declaration of Independence. Fifty men from 13 states signed the document on August 2 in 1776. The other six signed over the course of the next year and a half. As the President of the Second Continental Congress, John Hancock signed first. He wrote his name very large. Some of the men abbreviated their first names, like Thomas Jefferson and Benjamin Franklin. All of the signers risked their lives when they signed the Declaration of Independence. Contrary to popular belief, the words of the Declaration of Independence did not gain immediate prominence. In fact, they remained obscure for decades. And yet the spirit of the Declaration caused ripples almost immediately, most famously with the French Revolution in 1789. The Haitian Revolution followed soon after, and the subsequent decades would see many Latin American countries continuing the fight for independence from colonial powers. In 1945, Vietnamese leader Ho Chi Minh also invoked the document when declaring Vietnamese independence from the French colonial empire.

Within the U.S., the women’s suffrage movement adapted the Declaration of Independence for their cause, asserting in the 1848 Declaration of Sentiments that “all men and women are created equal.” Meanwhile, the country’s celebrations of independence haunted enslaved people and abolitionists like Frederick Douglass, whose 1852 speech “What to the Slave is the Fourth of July?” pondered the nation’s shortcoming despite its dedication to values like liberty. As Douglass said, “This Fourth of July is yours, not mine. You may rejoice, I must mourn.”

As World War I came to a close, leaders from Eastern Europe gathered inside Independence Hall on October 26, 1918 to sign the Declaration of Common Aims of the Independent Mid-European Nations. Those gathering in Independence Hall that day sought to bring autonomy to the nations of the former Austro-Hungarian and Ottoman Empires. The signers pledged their mutual support and their belief that “it is the unalienable right of every people to organize their own governments on such principles and in such forms as they believe will best promote their welfare, safety, and happiness.”

After the signing ceremony, Doctor Thomas Masaryk, the first president of Czechoslovakia, read the Declaration of Common Aims on Independence Square, just as John Nixon read the Declaration of Independence on July 8, 1776.

The Declaration of Independence is one of the most important documents in the history of the United States. It was an official act taken by all 13 American colonies in declaring independence from British rule.

People in the colonies were unhappy that they did not have a say in their government and still had to pay taxes. The Stamp Act of 1765 collected taxes on paper goods like legal documents, newspapers, and playing cards. In one act of protest, men dumped the cargo of a ship full of British tea into Boston Harbor in 1773; this is now called the Boston Tea Party. In 1775, the colonists went to war with Great Britain.

The war between the colonies and Great Britain was called the American Revolutionary War (1775-1783). A group of men came together in the summer of 1776 to find ways to become independent from Great Britain. The committee included John Adams, Benjamin Franklin, Thomas Jefferson, Robert R. Livingston, and Roger Sherman.

Writing the Declaration of Independence

The Declaration of Independence was originally written by Thomas Jefferson. Benjamin Franklin, John Adams, and Jefferson then worked together to make changes to the document. The final draft of the Declaration of Independence was adopted on July 4, 1776, but the actual signing of the final document was on August 2, 1776.

Writing and signing the Declaration of Independence took courage, but it was an important step in the founding of our Government. A famous phrase from the Declaration is “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.”

Declaration of Independence facts and figures:

  • John Hancock was the first to sign. His signature was so large and bold that people use ‘John Hancock’ to mean a signature.
  • The Declaration of Independence is on public display in the Rotunda of the National Archives in Washington, DC.

The The Declaration of Independence, completed and signed in July of 1776, marked the official separation between the 13 colonies and Great Britain. An armed struggle between the colonies and Britain had begun just over a year before, with the Battles of Lexington and Concord. The formal declaration of independence established the new American revolutionary government and officially declared war against Great Britain. The primary purpose of the declaration was to assist the Second Continental Congress in obtaining aid from foreign countries. The document also clearly outlines the history of abuses the colonists had suffered under British rule since the end of the French and Indian war in 1763.

Prior to the French and Indian war, the colonists had enjoyed over a hundred years of "salutary neglect." In other words, although laws were in place to maintain the subordinate status of the colonies to Great Britain, they were usually not enforced. After the French and Indian war, which increased Britain's share of North America, King George III and Parliament sought to establish firm control over the land newly obtained from France, and to help pay war debts by taxing the colonies. They did this by enacting a number of acts that either taxed the colonists or placed stricter controls on trade. These laws included the Sugar Act (1764), the Stamp Tax (1765), the Townshend Acts (1767), and the Tea Act (1773). Additionally, Parliament enacted the Quartering Act (1765) which forced colonists to help pay for the British military stationed in the colonies.

Colonists initially protested these acts through peaceful means such as petition, boycott, and committees. They argued that since they had no representation in Parliament, they could not be rightfully taxed by Parliament. As their petitions were repeatedly ignored, and taxes continually added, colonists turned to increasingly more destructive actions, like the Boston Tea Party of 1774. In response to this rebellious action by the Massachusetts Colony, the King and Parliament exacted punishment through legislation referred to by colonists as the "Intolerable Acts."

The Intolerable Acts sparked the colonies to call an inter-colonial congress for the purpose of discussing a unified response to the King and Parliament. This First Continental Congress, as it was called, met in September 1774 in Philadelphia. All 13 colonies were present except for Georgia. The Congress drafted a declaration claiming that the Intolerable Acts were unconstitutional, that the colonists retained the same civil rights as English citizens, and that they would boycott all English goods until reconciliation was reached. The negotiations never happened. Instead, tensions continued to mount between the colonists and Great Britain. The First Continental Congress agreed to meet again in May 1775 if no reconciliation had been reached. At this Second Continental Congress, all thirteen colonies were present.

It took 14 months, military mobilization, persuasive pamphleteering, and the further abuse of colonial rights before all 13 colonies agreed to pursue independence. At issue were political as well as practical concerns. Upper class colonists tended to fear the lower class gaining too much power through revolution. Middle class colonists could not afford to see their businesses continue to decline due to trade restrictions. All colonists resented that the King and Parliament denied them representative government and their civil rights. However, they also doubted whether they would be strong enough to resist the British military.

Early in 1776, Thomas Paine published his pamphlet Common Sense, which won over many colonists to the cause of independence. Meanwhile, the congress had sent the King an Olive-Branch Petition as a last effort towards reconciliation. Not only did he refuse to respond to the colonists' plea, he sent an additional 20,000 troops to North America and hired mercenaries from Germany to bolster his military force. An all-out war seemed imminent and even moderate delegates realized that in order to obtain much-needed military support from France, they would have to declare themselves wholly independent from Great Britain. Richard Henry Lee of Virginia proposed a resolution for independence in June of 1776. The Congress appointed a committee to draft a declaration of independence that consisted of John Adams (MA), Benjamin Franklin (PA), Thomas Jefferson (VA), Robert Livingston (NY) and Roger Sherman (CT).

The job of drafting the Declaration of Independence fell to the youngest member of the committee, Thomas Jefferson. In composing the declaration, Jefferson drew on ideas from the Enlightenment, especially those of John Locke. Not only did the declaration represent a milestone in the history of the United States, it also turned the political philosophies of 18th century Europe into real political practice.
