Step-by-step explanation:
The Boston Massacre was used as an example of pre-Revolutionary War propaganda by the Sons of Liberty. They used public media, such as prints and engravings, to portray the British soldiers as ruthless oppressors and the protesters as helpless victims. The event presented a perfect opportunity for propaganda because it involved a clash between the colonists and British soldiers, which highlighted the growing tensions and resentment towards British rule. This propaganda also related to the class structure in the colonies, as it highlighted the power dynamics between the ruling British elite and the common colonists.
