Common Sense is a 47-page pamphlet written by Thomas Paine in 17751776 advocating independence from Great Britain to people in the Thirteen Colonies. Writing in clear and persuasive prose, Paine marshaled moral and political arguments to encourage common people in the Colonies to fight for egalitarian government. It was published anonymously on January 10, 1776, at the beginning of the American Revolution and became an immediate sensation.

It was sold and distributed widely and read aloud at taverns and meeting places. In proportion to the population of the colonies at that time (2.5 million), it had the largest sale and circulation of any book published in American history. As of 2006, it remains the all-time best-selling American title and is still in print today.Common Sense made public a persuasive and impassioned case for independence, which had not yet been given serious intellectual consideration. Paine connected independence with common dissenting Protestant beliefs as a means to present a distinctly American political identity and structured Common Sense as if it were a sermon. Historian Gordon S. Wood described Common Sense as "the most incendiary and popular pamphlet of the entire revolutionary era."The text was translated into French by Antoine Gilbert Griffet de Labaume in 1790.

Thomas Paine (born Thomas Pain; February 9, 1737 [O.S. January 29, 1736] – June 8, 1809) was an English-born American political activist, philosopher, political theorist, and revolutionary. He authored Common Sense (1776) and The American Crisis (1776–1783), two of the most influential pamphlets at the start of the American Revolution, and helped inspire the patriots in 1776 to declare independence from Great Britain. His ideas reflected Enlightenment-era ideals of transnational human rights.Born in Thetford, Norfolk, Paine emigrated to the British American colonies in 1774 with the help of Benjamin Franklin, arriving just in time to participate in the American Revolution. Virtually every rebel read (or listened to a reading of) his 47-page pamphlet Common Sense, proportionally the all-time best-selling American title, which catalysed the rebellious demand for independence from Great Britain. The American Crisis was a pro-revolutionary pamphlet series. Paine lived in France for most of the 1790s, becoming deeply involved in the French Revolution. He wrote Rights of Man (1791), in part a defense of the French Revolution against its critics. His attacks on Anglo-Irish conservative writer Edmund Burke led to a trial and conviction in absentia in England in 1792 for the crime of seditious libel.

The British government of William Pitt the Younger, worried by the possibility that the French Revolution might spread to Britain, had begun suppressing works that espoused radical philosophies. Paine's work, which advocated the right of the people to overthrow their government, was duly targeted, with a writ for his arrest issued in early 1792. Paine fled to France in September where, despite not being able to speak French, he was quickly elected to the French National Convention. The Girondins regarded him as an ally; consequently, the Montagnards, especially Maximilien Robespierre, regarded him as an enemy.

In December 1793, he was arrested and was taken to Luxembourg Prison in Paris. While in prison, he continued to work on The Age of Reason (1793–1794). James Monroe, a future President of the United States, used his diplomatic connections to get Paine released in November 1794. Paine became notorious because of his pamphlets and attacks on his former allies, who he felt had betrayed him. In The Age of Reason and other writings he advocated Deism, promoted reason and freethought, and argued against institutionalized religions in general and the Christian doctrine in particular. In 1796, he published a bitter open letter to George Washington, whom he denounced as an incompetent general and a hypocrite. He published the pamphlet Agrarian Justice (1797), discussing the origins of property and introduced the concept of a guaranteed minimum income through a one-time inheritance tax on landowners. In 1802, he returned to the U.S. When he died on June 8, 1809, only six people attended his funeral, as he had been ostracized for his ridicule of Christianity and attacks on the nation's leaders.
