The greatest of all Civil War campaigns, Gettysburg was the turning point of the turning point in our nation’s history. Volumes have been written about this momentous three-day battle, but recent histories have tended to focus on the particulars rather than the big picture: on the generals or on single days of battle—even on single charges—or on the daily lives of the soldiers. In Gettysburg Sears tells the whole story in a single volume.

As a young man, Frederick Douglass (1818-1895) escaped from slavery in Baltimore, Maryland. He was fortunate to have been taught to read by his slave owner mistress, and he would go on to become one of the major literary figures of his time. He wrote three versions of his autobiography over the course of his lifetime and published his own newspaper. His very existence gave the lie to slave owners: with dignity and great intelligence, he bore witness to the brutality of slavery.

In 1855, with the United States at odds over slavery, the lawyer Abraham Lincoln wrote a note to his best friend, the son of a Kentucky slaveowner. Lincoln rebuked his friend for failing to oppose slavery. But he added: “If for this you and I must differ, differ we must,” and said they would be friends forever. Throughout his life and political career, Lincoln often agreed to disagree. Democracy demanded it, since even an adversary had a vote.

To the framers of the Constitution, political parties were a fatal threat to republican virtues. They had suffered the consequences of partisan politics in Britain before the American Revolution, and they wanted nothing similar for America. Yet parties emerged even before the Constitution was ratified, and they took firmer root in the following decade. In Founding Partisans, master historian H. W. Brands has crafted a fresh and lively narrative of the early years of the republic as the Founding Fathers fought one another with competing visions of what our nation would be.

The fourth and final year of the Civil War offers one of that era’s most compelling narratives, defining the nation and one of history’s great turning points. Now, S.C. Gwynne’s Hymns of the Republic addresses the time Ulysses S. Grant arrives to take command of all Union armies in March 1864 to the surrender of Robert E. Lee at Appomattox a year later. He breathes new life into the epic battle between Lee and Grant; the advent of 180,000 black soldiers in the Union army; Sherman’s March to the Sea; the rise of Clara Barton; and much more.
