The overwhelming majority of American colonists had either been born in England or were children of those born in England, and therefore many colonists felt ambivalent about-if not completely opposed to-the movement for independence. Even those who sought independence were worried that Britain was too powerful to defeat. But a student of the Enlightenment, Thomas Paine, urged colonists to support the movement. In his widely distributed pamphlet, Common Sense, he assailed the monarchy as an encroachment on Americans' natural rights and appealed to the colonists to form a better government. The printing press, the powerful tool of the Protestant Reformation, quickly became a powerful tool for the American Revolution.
