On this day 250 years ago, citizens of Boston met under the Liberty Tree and adopted the Resolutions of the Town of Boston written by Sam Adams that resolved

“That a virtuous and steady opposition to the Ministerial Plan of governing
America, is absolutely necessary to preserve even the shadow of Liberty, and is a duty which every Freeman in America owes to his Country to himself and to his Posterity [and]

That whoever shall . . . in any wise aid or abet in unloading receiving or vending the Tea sent or to be sent out by the East India Company while it remains subject to the payment of a duty here is an Enemy to America”
