at a town meeting held at faneuil hall in boston on october 28, 1767, boston freeholders and residents discussed the implications of the brutal townshend acts levied against the colonists. the townshend acts were a set of four acts passed by the british parliament in the summer of 1767 in order to generate revenue for the crown (through duties on goods such as lead, glass, paper, and tea) as well as exert british control over the increasingly rebellious colonists.

during the oct. 28 meeting, the bostonians found:

as a result, the citizens unanimously voted to boycott all british-made goods.
