Answer:
The objective of the Sons of Liberty was to make the government repeal the Stamp Act which happened on March 18, 1766 . Their actions, violent or not, were aimed at intimidating officials and stamp distributors forcing them to resign. The group also put pressure on merchants who did not act in accordance with the non-importation agreement. The best work at undermining the Stamp Act was done by newspapers.
