On this day 250 years ago mass meetings were held in both Charleston and New York City to make plans for blocking the sale of British East India Company tea. 

A general meeting of the inhabitants of Charleston chaired by George Gabriel Powell met in the Exchange to address the tea aboard the ship London in Charleston Harbor. The meeting adopted resolutions that tea “ought not to be landed, received, or vended in this Province” and that “all Persons whatever was forbid to purchase [tea], on pain of forfeiting the Resentment of the people of this Province.” [18th Century capitalization was idiosyncratic to say the least; why they capitalize “Persons” but not “people” in the same sentence is beyond me.]

On the same day 2000 people met at the city hall in New York to discuss proposals for blocking tea onboard the Nancy on its way to New York, but did not adopt any resolutions.
