Sons of Liberty formed to resist taxes

In 1765, colonial protest leaders in Boston, New York, Newport, and other towns formed groups that came to be known as the Sons of Liberty in response to the Stamp Act. Samuel Adams, John Hancock, Isaac Sears, and other local activists used public meetings, liberty poles, broadsides, and crowd action to intimidate stamp distributors and rally resistance. The movement had no single charter or central office, but its name became a recognized banner for direct protest against imperial taxation.

The Sons of Liberty changed resistance politics by carrying the constitutional argument against taxation without representation into the streets and docks of seaport towns. Merchants, artisans, and printers could now cooperate with elite lawyers and legislators in a campaign that linked local grievances to colonial rights. Their tactics also forced moderates to reckon with popular action, because royal officers and stamp agents often resigned under public pressure before the law could be enforced.

The movement helped prepare the way for the Stamp Act Congress, the nonimportation agreements of the Townshend crisis, and the Boston Tea Party of 1773. It also demonstrated that revolutionary organization would rely not only on assemblies and petitions but also on networks capable of mobilizing ordinary colonists in defense of claimed constitutional rights.
