On January 9, 1776, writer Thomas Paine publishes his pamphlet “Common Sense,” setting forth his arguments in favor of American independence. Although little used today, pamphlets were an important medium for the spread of ideas in the 16th through 19th centuries.

Originally published anonymously, “Common Sense” advocated independence for the American colonies from Britain and is considered one of the most influential pamphlets in American history. Credited with uniting average citizens and political leaders behind the idea of independence, “Common Sense” played a remarkable role in transforming a colonial squabble into the American Revolution.

At the time Paine wrote “Common Sense,” most colonists considered themselves to be aggrieved Britons. Paine fundamentally changed the tenor of colonists’ argument with the crown when he wrote the following: “Europe, and not England, is the parent country of America. This new world hath been the asylum for the persecuted lovers of civil and religious liberty from every part of Europe. Hither they have fled, not from the tender embraces of the mother, but from the cruelty of the monster; and it is so far true of England, that the same tyranny which drove the first emigrants from home, pursues their descendants still.”

Paine was born in England in 1737 and worked as a corset maker in his teens and, later, as a sailor and schoolteacher before becoming a prominent pamphleteer. In 1774, Paine arrived in Philadelphia and soon came to support American independence. Two years later, his 47-page pamphlet sold some 500,000 copies, powerfully influencing American opinion. Paine went on to serve in the U.S. Army and to work for the Committee of Foreign Affairs before returning to Europe in 1787. Back in England, he continued writing pamphlets in support of revolution. He released “The Rights of Man,” supporting the French Revolution in 1791-92, in answer to Edmund Burke’s famous “Reflections on the Revolution in France” (1790). His sentiments were highly unpopular with the still-monarchal British government, so he fled to France, where he was later arrested for his political opinions. He returned to the United States in 1802 and died in New York in 1809.
