The Sons of Liberty was an organization of American colonists that was created in the Thirteen American Colonies. The secret society was formed to protect the rights of the colonists and to fight taxation by the British government. They played a major role in most colonies in battling the Stamp Act in 1765. After that they declined sharply and in most places faded away. The name is sometimes loosely used to characterize other Local secret Patriot groups in the coming of the American Revolution.
In the popular imagination, the Sons of Liberty was a formal underground organization with recognized members and leaders. More likely, the name was an underground term for any men resisting new Crown taxes and laws. The well-known label allowed organizers to issue anonymous summons to a Liberty Tree, "Liberty Pole", or other public meeting-place. Furthermore, a unifying name helped to promote inter-Colonial efforts against Parliament and the Crown's actions. Their motto became, "No taxation without representation."
