Samuel Adams helped communicate the threats to Boston to other colonies by leading the Sons of Liberty. The Sons of Liberty was a secret organization that was formed in Boston in 1765 to protest against the Stamp Act. Samuel Adams was one of its key leaders, along with Paul Revere and other prominent Bostonians. The group used tactics such as boycotts, demonstrations, and acts of civil disobedience to resist British rule and promote colonial rights. Adams was a skilled orator and organizer who played a significant role in rallying support for the American Revolution. His efforts helped to unite the colonies and build momentum towards independence from Great Britain.
