For the 250th anniversary of John Quincy Adams's birth, a landmark new selected edition of an American masterpiece: the incomparable self-portrait of a man and his times from the Revolution to the coming of the Civil War.

The diary of John Quincy Adams is one of the most extraordinary works in American literature. Begun in 1779 at the age of twelve and kept more or less faithfully until his death almost 70 years later, and totaling some fifteen thousand closely-written manuscript pages, it is both an unrivaled record of historical events and personalities from the nation's founding to the antebellum era and a masterpiece of American self-portraiture, tracing the spiritual, literary, and scientific interests of an exceptionally lively mind. Now, for the 250th anniversary of Adams's birth, Library of America and historian David Waldstreicher present a two-volume reader's edition of diary selections based for the first time on the original manuscripts, restoring personal and revealing passages suppressed in earlier editions.

Volume I begins during the American Revolution, with Adams's first entry, as he prepares to embark on a perilous wartime voyage to Europe with his father, diplomat John Adams, and records his early impressions of Franklin and Jefferson and of Paris on the eve of revolution; it details his abbreviated but eventful years of study at Harvard and his emergence into the world of politics in his own right, as American minister to the Netherlands and to Prussia, and then as a U. S. senator from Massachusetts; and it reveals a young man at war with his passions, before finding love with the remarkable Louisa Catherine Johnson. In passages that form a kind of real-world War and Peace, the diary follows the young married couple to St. Petersburg, where as U.S. minister Adams is a witness to Napoleon's invasion of Russia. Its account of the negotiations at Ghent to end the War of 1812, where Adams leads the American delegation, is the perhaps the most detailed and dramatic picture of a diplomatic confrontation ever recorded. Volume 1 concludes with his elevation as Secretary of State under James Monroe, as he takes the fore in a fractious cabinet and emerges as the principal architect of what will become known as the Monroe Doctrine.

Volume 2 opens with the political maneuverings within and outside Monroe's cabinet to become his successor, a process that culminates in Adams's election to the presidency by the House of Representatives after the deadlocked four-way contest of 1824. Even as Adams takes the oath of office, rivals Henry Clay, his Secretary of State, John C. Calhoun, his vice president, and an embittered Andrew Jackson, eye the election of 1828. The diary records in candid detail his frustration as his far-sighted agenda for national improvement founders on the rocks of internecine political factionalism, conflict that results in his becoming only the second president, with his father, to fail to secure reelection. After a short-lived retirement, Adams returns to public service as a Congressman from Massachusetts, and for the last seventeen years of his life he leads efforts to resist the extension of slavery and to end the notorious "gag rule" that stifles debate on the issue in Congress. In 1841 he further burnishes his reputation as a scourge of the Slave Power by successfully defending African mutineers of the slave ship Amistad before the Supreme Court. The diary achieves perhaps its greatest force in its prescient anticipation of the Civil War and Emancipation, an "object," as Adams described it during the Missouri Crisis, "vast in its compass, awful in its prospects, sublime and beautiful in its issue."
