The publication that significantly influenced the spread of revolutionary ideas during the American Revolution was "Common Sense," written by Thomas Paine in 1776. This pamphlet boldly argued for American independence from British rule and challenged the legitimacy of monarchy. Paine's accessible writing style and compelling arguments resonated with colonists, encouraging many to consider the necessity of a break from Britain. "Common Sense" effectively galvanized public opinion in favor of revolution, contributing to the growing sentiment for independence and ultimately influencing the Continental Congress's decision to declare independence.
