John and Abigail Adams remained fully engaged in American political life after they left Washington, DC, for retirement in Quincy. A highlight of Volume 15 of Adams Family Correspondence is a series of letters between Abigail Adams and Thomas Jefferson that debated fundamental questions of the nation’s tumultuous early years. A new generation rose in prominence in the period covered in the volume, with John Quincy Adams returning from abroad to take a seat in the United States Senate just in time to break with the Federalists and support the Louisiana Purchase. The family commented on other events of the era—Jefferson’s dismantling of John Adams’s judicial reforms, the mobilization of the US Navy for the Barbary wars, the growing bane of British impressment, and the duel that killed Alexander Hamilton. Equally compelling family stories emerge in the volume’s 251 letters. The failure of a British banking firm proved calamitous to the family’s finances, compelling John Quincy to quietly finance his parents’ retirement. Thomas Boylston Adams, acting as an occasional editor of the Port Folio, carved out his public persona as a man of letters. Louisa Catherine Adams wrote of motherhood and adjusting to a new country of residence while providing a spirited perspective on Washington society. As always, the heart of Adams Family Correspondence is Abigail Adams, who survived a near-fatal fall to continue providing letters of insight and wit that once again show why the correspondence of the Adams family is a national treasure.

Vice President John Adams and the US government faced a turbulent world of rebellion in this volume of the Papers of John Adams, which chronicles the period from March 1791 to January 1797. The grim shadow of the French Revolution and the whirlwind of a massive European war left political leaders like Adams struggling to uphold the young nation's neutrality. "I Suffer inexpressible Pains, from the bloody feats of War and Still more from those of Party Passions," he observed. With the federal system newly in place, fresh challenges crept in on all sides. Adams and his colleagues sought to bolster the government against the effects of the Whiskey Rebellion, a seething partisan press, a brutal yellow fever epidemic in Philadelphia, and violent clashes with Native peoples on the Ohio frontier. Working with George Washington and an increasingly fractious cabinet, Adams approached a set of issues that defined US foreign policy for decades to come, including the negotiation, ratification, and funding of the controversial Jay Treaty, as well as the awkward cultivation of ties with France. Revealing exchanges to Adams from son John Quincy, a junior statesman who sent rich reports from war-torn Europe, underline the family's enduring commitment to public service. Pausing on the cusp of his presidency, John Adams amplified his lifelong dedication to sustaining democracy, amid bouts of internal and external crisis: "I am happy that it has fallen to my share to do some thing towards setting the Machine in motion," he wrote.

John Adams's shaping of the vice presidency dominates this volume of the Papers of John Adams, which chronicles a formative era in American government spanning June 1789 to February 1791. As the first federal Congress struggled to interpret the US Constitution and implement a new economic framework, Adams held fast to federalist principles and staked out boundaries for his executive powers. Meeting in New York City, Adams and his colleagues warred over how to collect revenue and where to locate the federal seat. They established and staffed the departments of state, treasury, and war. Adams focused on presiding over the Senate, where he broke several ties. Enduring the daily grind of politics, he lauded the "National Spirit" of his fellow citizens and pledged to continue laboring for the needs of the American people. "If I did not love them now, I would not Serve them another hour-for I very well know that Vexation and Chagrine, must be my Portion, every moment I shall continue in public Life," Adams wrote. He plunged back into writing, using his Discourses on Davila to synthesize national progress with republican history. Whether or not the union would hold, as regional interests impeded congressional action, remained Adams's chief concern. "There is every Evidence of good Intentions on all sides but there are too many Symptoms of old Colonial Habits: and too few, of great national Views," he observed. Once again, John Adams's frank letters reveal firsthand the labor of nation-building in an age of constitutions.

"Huzza for the new World and farewell to the Old One," John Adams wrote in late 1787, wrapping up a decade's worth of diplomatic service in Europe. Volume 19 of the Papers of John Adams chronicles Adams's last duties in London and The Hague. In the twenty-eight months documented here, he petitioned the British ministry to halt impressment of American sailors, toured the English countryside, and observed parliamentary politics. Adams salvaged U.S. credit by contracting two new Dutch loans amid the political chaos triggered by William V's resurgence. Correspondents like Thomas Jefferson and the Marquis de Lafayette mulled over the Anglo-American trade war that followed the Revolution and reported on the French Assembly of Notables-topics that Adams commented on with trademark candor. He wrote the final two volumes of his work, A Defence of the Constitutions of Government of the United States of America. Adams yearned to return home and see the American republic take shape. "For a Man who has been thirty Years rolling like a stone," Adams wrote, the choice was whether to "set down in private Life to his Plough; or push into turbulent scenes of Sedition and Tumult; whether be sent to Congress, or a Convention or God knows what." Back on his native soil of Massachusetts in June 1788, Adams settled into rural retirement with wife Abigail and watched the U.S. Constitution's ratification evolve. By volume's end, John Adams again resumes public life, ready to serve as America's first vice president.
