What was the Sons of Liberty?

The Sons of Liberty was a loose network of colonial organizations formed in 1765 to oppose the Stamp Act, and over the following decade they coordinated resistance to British taxation through public protest, intimidation of royal officials, mob action, intercolonial communication, and propaganda campaigns. The name traces to a February 1765 speech by Isaac Barré in the British House of Commons, in which Barré called the colonists "these Sons of Liberty" defending their rights against unjust taxation. Colonists adopted the name as a badge of honor.

The first organized chapter formed in the summer of 1765 in Boston as the Loyal Nine, a small group of artisans and printers led by shoemaker Ebenezer Mackintosh, distiller Thomas Chase, brazier John Avery, and printer Benjamin Edes. They quickly grew into the Boston Sons of Liberty under the political leadership of Samuel Adams, James Otis, and John Hancock. New York's Sons of Liberty under Isaac Sears and John Lamb organized in late 1765, and chapters appeared in Philadelphia, Charleston, Newport, Providence, Albany, Hartford, New Haven, and other colonial towns. By early 1766 the various local groups were corresponding regularly.

The Sons of Liberty engaged in several kinds of resistance. They organized public protests and effigy hangings, most famously the August 14, 1765 hanging of stamp distributor Andrew Oliver in effigy from a Boston elm that became known as the Liberty Tree. They forced stamp distributors throughout the colonies to resign their commissions, often through intimidation that bordered on violence. They organized merchant nonimportation agreements and enforced them through public shaming of violators. They published pamphlets, broadsides, and newspaper articles, and they collected signatures on petitions to Parliament and the Crown.

After the Stamp Act was repealed on March 18, 1766, the organizations went into partial dormancy but reactivated when the Townshend Duties of 1767 imposed new taxes. They led the protests against the customs commissioners in Boston in 1768, organized resistance to the Tea Act in 1773 (Sons of Liberty members carried out the Boston Tea Party on December 16, 1773), and helped form the Committees of Correspondence in 1772 that linked Patriot leaders across the colonies. By 1775 many Sons of Liberty had moved into formal Patriot militias and the Continental Army.

The organization's lasting contribution was demonstrating that ordinary colonists, not just colonial elites, could engage in coordinated political action across colony lines, a precedent that shaped the later Continental Congresses and revolutionary committees.
