The Sons of Liberty were a group of people in Boston at the time of the American Revolution. They were led by Samuel Adams, James Otis, and Paul Revere. Other well-known members included Benedict Arnold and Patrick Henry. They were in favor of rights of colonial Americans, which meant they often did not like the British. Some people thought the Sons of Liberty were a mob. The Sons of Liberty were the main group involved in the Boston Massacre and the Boston Tea Party. They also participated in the Stamp Act.
