What did Thomas Paine helped explain the reason for Independence?

Thomas Paine played a crucial role in articulating the case for American independence through his pamphlet "Common Sense," published in 1776. In it, he argued that monarchy was an illegitimate form of government and that the colonies had the right to self-governance. Paine's clear and persuasive writing galvanized public opinion, making the idea of independence more accessible and appealing to ordinary colonists. His work helped to unify revolutionary sentiment and laid the philosophical groundwork for the Declaration of Independence.
