The Massachusetts Circular Letter was a statement written by Samuel Adams and James Otis Jr., and passed by the Massachusetts House of Representatives (as constituted in the government of the Province of Massachusetts Bay, not the current constitution) in February 1768 in response to the Townshend Acts. Reactions to the letter brought heightened tensions between the British Parliament and Massachusetts, and resulted in the military occupation of Boston by the British Army, which contributed to the coming of the American Revolution.
