What was the major goal of the Sons of Liberty?

The Sons of Liberty were originally formed in Boston as a result of the British passing the Stamp Act of 1765. The organization expanded to include members from other cities and colonies.

Prominent members included Paul Revere, Thomas Young, Joseph Warren, Alexander McDougall, Patrick Henry, John Hancock, Isaac Sears, John Lamb, James Otis, Thomas Crafts, Jr., John Adams, and his cousin, Samuel Adams
