The book shows that, contrary to recent historians' interpretations, Jefferson consistently viewed New England, especially Massachusetts, as a vital and integral part of the national community. He had no desire for the other states in the Union to "destroy" or subordinate it, not even during the War of 1812, when the New England states refused to join the war effort and some of their leaders conspired with the British to make a separate peace. The book provides a welcome, detailed analysis of Jefferson's nationalist credo, specifically in connection with his lifelong interaction with the New England states and his storied friendship with John Adams.
