The primary role of the Secret Society known as the Sons of Liberty was to resist British oppression and advocate for colonial rights leading up to the American Revolution. Formed in the 1760s, this organization opposed British taxation policies and promoted protests, including the famous Boston Tea Party. Their efforts galvanized public sentiment against British rule and united colonists across the American colonies. The Sons of Liberty played a crucial role in the push for independence, becoming symbols of American resistance and patriotism.
