Which document served as a rationale for the Declaration of Independence?

"Common Sense," authored by Thomas Paine in 1776, played a critical role in shaping public opinion in favor of independence from British rule. It articulated the argument for self-governance and the natural rights of individuals, emphasizing that a government derives its legitimacy from the consent of the governed. Paine's passionate prose resonated with the colonists and provided a compelling rationale for asserting independence, making it a significant influence on the Founding Fathers as they drafted the Declaration of Independence.

In contrast, the U.S. Constitution and the Federalist Papers were developed after the Declaration of Independence and focus on the structure of government and the principles of governance. The Bill of Rights, which comprises the first ten amendments to the Constitution, also came later and serves to protect individual liberties rather than address the reasons for seeking independence. Thus, "Common Sense" directly aligned with the ideological framework that underpinned the Declaration, justifying the colonies’ decision to break free from British authority.
