In colonial america, who were the sons of liberty?

The Sons of Liberty was a secret revolutionary organization that was created in the Thirteen American Colonies to advance the rights of the European colonists and to fight taxation by the British government. It played a major role in most in battling the Stamp Act in 1765. The group officially disbanded after the Stamp Act was repealed. However, the name was applied to other local separatist groups during the years preceding the American Revolution.
