In the introduction to Frederick Douglass’s second autobiography, “My Bondage and My Freedom,” published in 1855, his friend James McCune Smith wrote that if a stranger landed in the United States and sought out its most prominent men by using newspapers and telegraph messages, he would discover Douglass. Born a slave in Maryland, Douglass had escaped to the North to become a renowned abolitionist orator and writer. He was, Smith said, the sort of person people would ask, “‘Tell me your thought!’ And somehow or other, revolution seemed to follow in his wake.”

For a century and a half Ulysses S. Grant has been a baffling and inspiring presence in the American literary and historical imaginations. Born in 1822 and raised by a pious Methodist mother, as a young man he was quiet, given to depressions, and lacking much ambition. Only his love of horses seemed to animate him and give him a reason to excel in his education at West Point, which his scheming father desired for him more than he did. In his thirties, he was a complete failure, at times a drunkard, destined to die forgotten. He found his vocation and success on America’s killing fields; his meteoric trajectory in the Civil War makes him a remarkable case of a nobody who became almost everything.

The Gilder Lehrman Center for the Study of Slavery, Resistance, and Abolition celebrated the 20th anniversary of its founding last Friday with a panel discussion on the life of Frederick Douglass, whose 200th birthday was also last week.

Two hundred years ago, one of the most important Americans was born close to the Tuckahoe River on the Eastern Shore of Maryland. Frederick Bailey didn’t know the exact date of his birth, so he chose Feb. 14. Twenty years later, when he escaped from slavery, he became Frederick Douglass. By the time of his death in 1895, he had become one of the greatest orators and writers of the century.

Impeaching an unfit president has consequences. But leaving one in office could be worse.

In recent months, I have grown obsessed with a seemingly simple question: Does the American political system have a remedy if we elect the wrong person to be president? There are clear answers if we elect a criminal, or if the president falls into a coma. But what if we just make a hiring mistake, as companies do all the time? What if we elect someone who proves himself or herself unfit for office — impulsive, conspiratorial, undisciplined, destructive, cruel?

White House Chief of Staff John F. Kelly was the guest for the premiere of Laura Ingraham’s new show on Fox News Channel on Monday night. During the interview, he outlined a view of the history of the Civil War that historians described as “strange,” “highly provocative,” “dangerous” and “kind of depressing.”

Two months after President Trump stirred fierce debate with a defense of Confederate monuments, his chief of staff, John F. Kelly, has waded back into the fray of Civil War history.
