In 1767 the British Parliament passed the Townshend Acts, designed to exert authority over the colonies. One of the acts placed duties on various goods, and it proved particularly unpopular in Massachusetts. Tensions began to grow, and in Boston in February 1770 a patriot mob attacked a British loyalist, who fired a gun at them, killing a boy. In the ensuing days brawls between colonists and British soldiers eventually culminated in the Boston Massacre.
