Final answer:
The Sons of Liberty were a group of activists and protesters who organized against the Stamp Act and other British-imposed taxes, using propaganda and direct actions like the Boston Tea Party.
Step-by-step explanation:
The group of organized activists and protesters that led anti-tax demonstrations and defied British law is known as the Sons of Liberty. This organization emerged to oppose the Stamp Act and other forms of taxation imposed on the colonies without representation.
They played a pivotal role in mobilizing colonial resistance through both peaceful protests and more direct actions, such as the Boston Tea Party. Members of the Sons of Liberty, including influential figures like Paul Revere, used propaganda to rally support and influence public opinion.
Alongside the Sons of Liberty, the Daughters of Liberty also contributed to the cause, promoting the boycott of British goods and contributing to the collective efforts that fueled the American Revolution.
